Subject: [PATCH 006/429] Fixes #4261

SWIG_Python_str_AsChar and SWIG_Python_str_DelForPy3 are no longer available in swig 4.2 (see : https://github.com/swig/swig/commit/f89dd59d4b82ece899087682fdb86e94d2611513 ),
this commit fixes the build for swig versions > 4.2.

Subject: [PATCH 032/429] fix numpy typing #4579

On older numpy versions, np.ndarray was less forgiving and wasn't allowing passing 1 argument instead of required 2.

And turned out numpy doesn't yet have typing for shapes (https://github.com/numpy/numpy/issues/16544), so all matrices and other shapes specified as `npt.NDArray[np.float64]`.

Fixed type discrepancies for `get_edges` and `get_faces` and also had to fix `import_ifc` as Blender apparently has problems with storing np.int32 in custom attributes (https://projects.blender.org/blender/blender/issues/121072), tested that Blender is okay with np.int32 in other cases we had (addressing BMesh.verts[i] where `i` is np.int32).

Subject: [PATCH 064/429] blenderbim - fix bug with unassigning material

When you would unassign material (e.g. implicitly by removing the object), it might have also removed materials slots from other occurrences of the same type.

Which may had some unexpected sideffects later on - as unassigned styles saving IFC project (BBIM unassigned styles based on a assumption that it was the user decision to remove the materials and related styles).

Subject: [PATCH 082/429] Reload current shading style after editing it #4567

Examples:
1) active shading type = EXTERNAL, now after changing it's SHADING attributes and accepting the changes, it will reload EXTERNAL shading back since it's the one that's active.
2) active shading type = SHADING, after adding EXTERNAL shader will reload SHADING style to the material.

+    """Adds a new geometric representation context
+
+    In IFC, physical objects may have zero, one, or multiple geometric
+    representations associated with it. For example, a building storey might
+    not have any geometry, but simply be a coordinate in space.
+    Alternatively, a wall might have a 3D body representation in the form of
+    a cuboid. As a final example, a door might also have a 3D body
+    representation of a 3D door panel and door frame, but may additionally
+    have a 2D door plan view representation of the door swing, and even a 2D
+    elevation view of the door, a 3D box representing the disabled clearance
+    zone of the door, a 2D profile representing the profile of the door to
+    cut out in a wall, and so on. In this situation, a door will have
+    multiple geometric representations.
+
+    To distinguish between the different purposes of multiple geometric
+    representations, each geometric representation must belong to a
+    geometric representation "context". There are typically always 2
+    contexts, one for 3D representations and one for 2D representations.
+    These 2 contexts then have subcontexts for things like the 3D body
+    representation, clearance representations, annotation representations,
+    and so on. Each representation of a physical IFC product (e.g. a door)
+    must be assigned to one of these subcontexts. Therefore setting up
+    appropriate contexts is critical prior to authoring any IFC model which
+    contains geometry.
+
+    There are two steps to setting up appropriate subcontexts. First, a 2D
+    and/or 3D context must be added. These must be always called the "Model"
+    context for 3D and the "Plan" context for 2D (even if the 2D geometry is
+    not a plan view). Then, one or more subcontexts are added using either
+    the "Model" or "Plan" as their parent. These subcontexts are further
+    distinguished using an "identifier" and "target view". The "identifier"
+    describes the purpose of the representation, and the "target view"
+    describes the typical diagrammatic presentation that context's geometry
+    should be viewed in. The most common identifiers you might use are:
+
+    - Body: for the actual shape of the object
+    - Box: the bounding box of the object (useful for shape analytics)
+    - Axis: the parametric line determining the shape of the object
+    - Profile: the elevation silhouette of the object, useful for cutting
+          out holes for the object to fit into host elements
+    - Footprint: the plan view silhouette of the object, useful for certain
+          quantity take-off rules
+    - Clearance: the clearance zone of the object
+    - Annotation: symbolic annotations typically used in diagrams or
+          drawings
+
+    The most common "target views" you might use are:
+
+    - MODEL_VIEW: for 3D geometry you might see in a BIM viewer
+    - PLAN_VIEW: for 2D geometry you might see in a plan representation
+    - ELEVATION_VIEW: for 2D geometry you might see in an elevation representation
+    - SECTION_VIEW: for 2D geometry you might see in a section representation
+    - GRAPH_VIEW: for 2D or 3D line or frame or path connectivity diagrams
+          you might use for structural frame analysis, axis-based parametric
+          modeling
+    - SKETCH_VIEW: for viewing abstract high-level representations such as
+          in bubble diagrams of spatial topology
+
+    This may sound like a lot, but after a few typical contexts are set up
+    at the beginning, it becomes easy to navigate and isolate geometry for
+    different purposes. There is also the concept of a target scale, which
+    represents the zoom level detail of geometry, but this is not currently
+    supported by this API. Setting up all these contexts are also optional,
+    and you may only use a single Model context and Body subcontext for
+    simple models, but this simplification sacrifices the ability of more
+    parametric or analytical usecases.

+    layered materials, composite materials, or other names in software.

+    There are three types of material sets:
 
-         - A layer set, used for layered construction such as walls, where the
-           element is parametrically made out of extruded layers, each layer
-           having a thickness defined. Even though this is known as a layer
-           "set" it is still recommended to use it for all standared layered
-           construction as it describes the intent of the element to be layered
-           construction and thus can be used for parametric editing.
-         - A profile set, used for profiled construction such as beams or
-           columns, where the element is parametrically made out of one or more
-           extruded profiles, where each profile may be parametric from a
-           standard section (e.g. standardised steel profile) or an arbitrary
-           shape (e.g. cold rolled sections, or skirtings, moldings, etc). Note
-           that even though this is called a profile "set", it should still be
-           used even if there is only a single profile. This is not available in
-           IFC2X3.
-         - A constituent set, used for arbitrary composite construction where
-           the object is made out of multiple materials. The constituents may be
-           explicitly defined via a shape, such as a window where the frame
-           geometry is made from one material and the panel geometry is made
-           from another material. Alternatively, the constituents may be
-           represented in terms of percentages, such as in mixtures like
-           concrete where there might be a percentage constituent of cement and
-           another percentage constituent of binder. This is not available in
-           IFC2X3.

+
+    Materials are typically assigned to the element types rather than
+    individual occurrences of elements. Individual occurrences would then
+    inherit the material from the type.
+
+    If the type has a material set, then the geometry of the occurrences
+    must comply with the material set. For example, if the type has a
+    constituent set, then it is expected that all occurrences also inherit
+    the geometry of the type, which is made out of those constituents.
+    Alternatively, if the type has a layer set, then all occurrences must
+    have geometry that has a thickness equal to the sum of all layers. If a
+    type has a profile set, then all occurrences must has the same profile
+    extruded along its axis.
+
+    For layers and profiles assigned to types, the occurrences must be
+    assigned an IfcMaterialLayerSetUsage or an IfcMaterialProfileSetUsage.
+    This allows individual occurrences to override the layered or profiled

-
-        Will unassign previously assigned material.
-
-        When a material is assigned to a product, it means that the product is
-        made out of that material. In its simplest form, a single material may
-        be assigned to a product, meaning that the entire product is made out of
-        that one material. Alternatively, a material set may be assigned to a
-        product, meaning that the product is made out of a set of materials.
-        There are three types of sets, including layered construction, profiled
-        materials, and arbitrary material constituents. See
-        ifcopenshell.api.material.add_material_set for details.
-
-        Materials are typically assigned to the element types rather than
-        individual occurrences of elements. Individual occurrences would then
-        inherit the material from the type.
-
-        If the type has a material set, then the geometry of the occurrences
-        must comply with the material set. For example, if the type has a
-        constituent set, then it is expected that all occurrences also inherit
-        the geometry of the type, which is made out of those constituents.
-        Alternatively, if the type has a layer set, then all occurrences must
-        have geometry that has a thickness equal to the sum of all layers. If a
-        type has a profile set, then all occurrences must has the same profile
-        extruded along its axis.
-
-        For layers and profiles assigned to types, the occurrences must be
-        assigned an IfcMaterialLayerSetUsage or an IfcMaterialProfileSetUsage.
-        This allows individual occurrences to override the layered or profiled
-        construction offset from a reference line.

-        Because there is a strict connection point, when the parent moves, all
-        nested children must move with the parent. Another example might be a

+
+    At its simplest usage, this may be used to edit the name of a property
+    set. It may also be used to add, edit, or remove properties, either
+    arbitrarily or using a property set template.
+
+    A list of properties are provided as a dictionary, where the keys are
+    property names, and values are property values. Keys that don't already
+    exist are interpreted as properties to be added. Keys that already exist
+    are interpreted as properties to be edited. A "None" value may specify a
+    property to be deleted.
+
+    Properties must have a data type. There are lots of data types in IFCs,
+    not just simple unitless data types like integers, booleans, text, but
+    also distinguishing between types of text, like labels versus
+    descriptive text. There are also lots of unit-based data types like
+    areas, volumes, lengths, power, density, flow rates, pressure, etc.
+
+    To ensure the appropriate data type is used for properties, a property
+    set template may be used. These can be seen as "property
+    specifications". A default selection is provided by buildingSMART, so
+    that all buildingSMART defined standard properties have exactly the same
+    data types and exactly the right property names without fear of invalid
+    data or typos. The built-in buildingSMART templates are always loaded.
+    However, you may also specify your own templates. If you try to add a
+    non-standard property that does not exist in either your own template or
+    in the built-in buildingSMART template, then you have the responsibility
+    to ensure that data types are always consistent and correct.
+
+    :param pset: The IfcPropertySet to edit.
+    :type pset: ifcopenshell.entity_instance

+    :type name: str, optional
+    :param properties: A dictionary of properties. The keys must be a string
+        of the name of the property. The data type of the value will be
+        determined by the property set template. If no property set
+        template is found, the data types of the Python values will
+        influence the IFC data type of the property. String values will
+        become IfcLabel, float values will become IfcReal, booleans will
+        become IfcBoolean, and integers will become IfcInteger. If more
+        control is desired, you may explicitly specify IFC data objects
+        directly. Note that provided `properties` might be mutated in the process.

-        property names, and values are property values. Keys that don't already
-        exist are interpreted as properties to be added. Keys that already exist
-        are interpreted as properties to be edited. A "None" value may specify a
-        property to be deleted.
-
-        Properties must have a data type. There are lots of data types in IFCs,
-        not just simple unitless data types like integers, booleans, text, but
-        also distinguishing between types of text, like labels versus
-        descriptive text. There are also lots of unit-based data types like
-        areas, volumes, lengths, power, density, flow rates, pressure, etc.
-
-        To ensure the appropriate data type is used for properties, a property
-        set template may be used. These can be seen as "property
-        specifications". A default selection is provided by buildingSMART, so
-        that all buildingSMART defined standard properties have exactly the same
-        data types and exactly the right property names without fear of invalid
-        data or typos. The built-in buildingSMART templates are always loaded.
-        However, you may also specify your own templates. If you try to add a
-        non-standard property that does not exist in either your own template or
-        in the built-in buildingSMART template, then you have the responsibility
-        to ensure that data types are always consistent and correct.

-            the property set name is not changed.
-        :type name: str, optional
-        :param properties: A dictionary of properties. The keys must be a string
-            of the name of the property. The data type of the value will be
-            determined by the property set template. If no property set
-            template is found, the data types of the Python values will
-            influence the IFC data type of the property. String values will
-            become IfcLabel, float values will become IfcReal, booleans will
-            become IfcBoolean, and integers will become IfcInteger. If more
-            control is desired, you may explicitly specify IFC data objects
-            directly. Note that provided `properties` might be mutated in the process.

+
+    Tasks are typically used for two purposes: construction scheduling and
+    facility management.
+
+    In construction scheduling, a task represents a job to be done in a work
+    schedule. Tasks are organised in a hierarchical manner known as a work
+    breakdown structure (WBS) and have lots of sequential relationships
+    (e.g. this task must finish before the next task can start) and date
+    information (e.g. durations, start dates). This is often represented as
+    a gantt chart and used to analyse critical paths to try and reduce
+    project time to stay on-time and within budget.
+
+    In facility management, a task represents a maintenance task to maintain
+    a piece of equipment. Tasks are broken down into a punch list, or simply
+    a bulleted or ordered sequence of tasks to be performed (e.g. turn off
+    equipment, check power connection, etc) in order to maintain the
+    equipment. Tasks will also typically have recurring scheduled dates in
+    line with the maintenance schedule. These maintenance tasks and
+    procedures are typically published as part of an operations and
+    maintenance manual.
+
+    All tasks must be grouped in a work schedule, either directly as a root
+    or top-level task, or indirectly as a child or subtask of a parent task.
+    In construction scheduling, tasks may be nested many times to create the
+    work breakdown structure, and the "leaf" tasks (i.e. tasks with no more
+    subtasks) are considered to be the activities with dates, whereas all
+    parent tasks are part of the breakdown structure used for categorisation
+    purposes. In facility management, top-level tasks represent the overall
+    maintenance job to be performed, and child tasks represent an ordered
+    list of things to do for that maintenance. These form a 2-level
+    hierarchy. No further child tasks are recommended.

-        To state that a product is contained in a space, you will use a
-        "containment" relationship. Containment is a very common relationship
-        used to create the hierarchical spatial decomposition tree. For example,

-        Containment is critical in construction management, to know which
-        objects are in which spaces, as often you would divide your construction
-        schedule into storey by storey, or zone by zone. Containment is also

-          equipment or object types for structural steel. If you just want to
-          give something a colour, this is what you need.
-        - Rendering, this is an advanced extension of shading, which includes
-          the definition of a shader for a rendering engine. You may select the
-          reflectance / lighting model such as PHYSICAL, for PBR style
-          rendering, or FLAT, for flat shading, or PHONG for older biased
-          rendering workflows. Based on the chosen lighting model, you may then
-          specify the appropriate colour maps, such as diffuse colours,
-          specularity, emissive component, etc. These lighting models are fully
-          compatible with glTF and X3D. This should be used if your model is
-          prepared to be rendered by a rendering engine which is compatible with
-          glTF / X3D shader descriptions. If you are doing archviz or 3D
-          rendering, this is what you need.
-        - Textures, this is a special type of Rendering presentation item that
-          uses image textures instead of single colours. Textures may be either
-          mapped using a bounding box stretch mapping, or with UV coordinates
-          for mesh-like geometry.
-        - Lighting, this is used to define photometrically accurate colour
-          parameters used in lighting simulation. If you are a simulationist,
-          this is what you need.
-        - Reflectance, this is a special type of Lighting presentation item
-          which includes some lesser used photometric properties, typically
-          required for advanced materials like glazing.
-        - External, this is for any other surface style defined using an
-          external URI. This is relevant if you are using a third-party non-glTF
-          compatible shader definition such as for Cycles, Renderman, V-Ray,

+    """Assigns a type to occurrences of an object
+
+    IFC supports the concept of occurrences and types. An occurrence is an
+    actual physical product in the real world: like a wall, a chair, a door,
+    a column, a pump, and so on.
+
+    Most occurrences have a corresponding type. A type describes either a
+    common shape and set of properties of a particular model of equipment,
+    or a construction typology. An occurrence may only have zero or one
+    type.
+
+    For example, architects would typically have a door schedule for
+    individual occurrences of doors and a door types schedule for a handful
+    of door types, described by the door hardware, frame, and panel. Other
+    examples might be window types or wall types. Structural engineers would
+    have a list of column types, beam types, slab types, etc, such as a 400
+    diameter column, a 500 diameter column, and so on. Services consultant
+    might nominate a particular type of sprinkler which have many
+    occurrences, or light fixture types, and so on.
+
+    Types are critical as they communicate to the procurement team what
+    types of equipment and products need to be procured. The individual
+    occurrences of that type tell them how many to procure. Types are also
+    critical in construction as they indicate succinctly how to manufacture
+    or construct something. For example, a wall type is enough information
+    for a builder to understand the build up and construction of a wall.
+    Types are used to help break down cost plans, or isolate portions of an
+    assembly process for construction scheduling. Types are also used in
+    facility maintenance, as occurrences sharing the same type can be
+    repaired in the same way or by replacing the same parts.
+
+    An occurrence of a type inherits all the properties and materials of the
+    type. For example, a 2HR fire rated wall type implies that all
+    wall occurrences of that wall type will also be 2HR fire rated.
+
+    A type may or may not have a geometric representation. If a type does
+    not have any representation, then the occurrences are free to have any
+    representation of their own. However, if a type has a representation,
+    all occurrences must have the same representation. For example, if a
+    light fixture downlight type has a representation of a cylinder, then
+    all occurrences must have exactly the same cylinder as its
+    representation. If you change the cylinder's shape of the type, then all
+    occurrence representations will also change.
+
+    If a type does not have any geometric representation, they may have a
+    parametric material representation. This may be either a parametric
+    layered material or parametric cross-sectional profile material. If this
+    is the case, the occurrence must be constructed out of the parametric
+    material. For example, if a wall type uses a list of parametric layers
+    indicating a thickness of 13mm plasterboard and 90mm stud, then the
+    thickness of every wall occurrence representation must be 103mm. The
+    length of each wall, however, may vary. Similarly, if a beam type has a
+    parametric profile material of an I-beam, then all beam occurrences must
+    also be this I-beam shape, though the length may vary.
+
+    It is highly recommended for every occurrence to have a type. There are
+    some exceptions to the rule, such as in heritage architecture or
+    as-built or dilapidation models, where existing conditions are
+    ambiguous, unknown or are so bespoke as to have no logical type.

-"""The entry module for IfcOpenShell
+"""Welcome to IfcOpenShell! IfcOpenShell provides a way to read and write IFCs.
 
-Typically used for opening an IFC via a filepath, or accessing one of the
-submodules.
+IfcOpenShell can open IFC files, read entities (such as walls, buildings,
+properties, systems, etc), edit attributes, write out ``.ifc`` files and more.
+
+This module provides primitive functions to interact with IFC, including:
+
+- For most users, you can open and read IFC models, see docs for :func:`open`.
+  This returns an :class:`file` object representing the IFC model. You can then
+  query the model to filter elements.
+- For developers, you can query the schema itself, see docs for
+  :func:`schema_by_name`. This returns a schema object which you can use to
+  analyse the definitions of IFC classes and data types.
+
+You may also be interested in:
+
+- For model authoring and editing operations, see :mod:`ifcopenshell.api`.
+- For extracting information from models, see :mod:`ifcopenshell.util`.
+- For processing geometry, see :mod:`ifcopenshell.geom`.
+
+
+For more details, consult https://docs.ifcopenshell.org/
 
 Example:
 
 .. code:: python
 
     import ifcopenshell
+
     print(ifcopenshell.version) # v0.7.0-1b1fd1e6
+
     model = ifcopenshell.open("/path/to/model.ifc")

-    """Base class for all IFC objects.
+    """Represents an entity (wall, slab, property, etc) of an IFC model
 
-    An instantiated entity_instance will have methods of Python and the IFC class itself.
+    An IFC model consists of entities. Examples of entities include walls,
+    slabs, doors and so on. Entities can also be non-physical things, like
+    properties, systems, construction tasks, colours, geometry, and more.
+
+    Entities are defined through an **IFC Class**. There are hundreds of **IFC
+    Classes** defined as part of the ISO standard by the buildingSMART
+    International organisation. The **IFC Class** defines the attributes of an
+    entity, as well as the data types and whether or not an attribute is
+    mandatory or optional.
+
+    IfcOpenShell's API dynamically implements the IFC schema. You will not find
+    documentation about available **IFC Classes**, or what attributes they
+    have.  Please consult the buildingSMART official documentation or start
+    reading :doc:`/introduction/introduction_to_ifc`.
+
+    In addition to the Python methods you see documented here, an instantiated
+    entity_instance will have attributes defined by its IFC class. For example,
+    an entity instance which is an IfcWall class will have a ``Name``
+    attribute, and an IfcColourRgb will have a ``Red`` attribute. Please
+    consult the buildingSMART official documentation.
 
     Example:
 
     .. code:: python
 
-        ifc_file = ifcopenshell.open(file_path)
-        products = ifc_file.by_type("IfcProduct")

+
+        # Note: the `Name` attribute is dynamic, based on the IFC class.

Subject: [PATCH 121/429] fix couple silent bugs importing containers

1) we were setting OwnerHistory to the "elevation" attribute of SpatialElement (in BIMSpatialProperties.containers)
2) we were setting "elevation" attribute at all when SpatialElement doesn't have "elevation" attribute

Though those bugs were silent since PropertyGroup doesn't alarm when we add a completely new attribute to it.

It seems that IFC doesn't specify that IfcRelAggregates.RelatedObjects should necessary have a placement. E.g. FreeCAD is using IfcGroups in RelatedObjects to store hierarchy in IFC.

Example - https://community.osarch.org/discussion/2144/object-information-spatial-container

+The most commonly used utilities to help you get started are:
+
+- See :mod:`ifcopenshell.util.element` which contains a lot of useful functions
+  for getting most common relationships on elements.
+- See :func:`ifcopenshell.util.element.get_psets` to get all properties of an
+  entity, like a wall.
+- See :func:`ifcopenshell.util.element.get_type` to get the corresponding type
+  object (e.g. the wall type definition) of a single occurrence (e.g. an
+  individual wall).
+- See :func:`ifcopenshell.util.placement.get_local_placement` to get the XYZ
+  placement point of a single object.
+- See :func:`ifcopenshell.util.unit.calculate_unit_scale` to convert between SI
+  units and project units.
+- See :mod:`ifcopenshell.util.shape` to calculate quantities from processed
+  geometry.

Subject: [PATCH 134/429] explicitly specify available imported symbols

Fix LSP warnings like ""entity_instance" is not exported from module "ifcopenshell"PylancereportPrivateImportUsage" for `ifcopenshell.file`, `ifcopenshell.entity_instance` etc.

After adding py.typed in 722201a1a it's now a typed library and all imported symbols in modules are considered private by default and should be added to `__all__` if they are supposed to be generally available from imported module.

See https://github.com/microsoft/pyright/blob/main/docs/typed-libraries.md#library-interface

We were incorrectly multiplying a shape matrix in SI units with a vertex in project units. We also didn't do a final check whether or not that final resultant coordinate was far away or not (for example, origin and vertex can cancel each other out)

Subject: [PATCH 160/429] Fix #4616. You can now create a new representation
 based off any other object. This makes it easy to custom model whatever you
 want as a starting point.

Subject: [PATCH 165/429] ifc2x3 tests - prevent using removed user/application

When some test was creating an element and then removing it, it would also remove user and application as they wasn't used anywhere else.
`ifcopenshell.util.element.remove_deep2(file, history)` we use in every api for element deletion can possibly remove user and application which can be unsafe if `get_user` is returning some specific entity that then will become invalid.

Also fixed tests breaking due ifcownerhistory and user/application appearing in ifc2x3.

Subject: [PATCH 174/429] avoid confusing TypeErrors from api calls

After ab5ea4c85 it was always throwing wrong singature errors like below even if TypeError was caused by some internal issues inside API - it was adding couple extra steps to traceback making errors more noisy.

TypeError: Incorrect function arguments provided for library.edit_library
attribute 'VersionDate' for entity 'IFC2X3.IfcLibraryInformation' is expecting value of type 'ENTITY INSTANCE', got 'str'.. You specified args (<ifcopenshell.file.file object at 0x0000027EB8E6BCD0>,) and settings {'library': #1=IfcLibraryInformation('Name','Version',$,$,$), 'attributes': {'Name': 'Name', 'Version': 'Version', 'VersionDate': 'VersionDate', 'Location': 'Location', 'Description': 'Description'}}
E
Correct signature is (file: ifcopenshell.file.file, library: ifcopenshell.entity_instance.entity_instance, attributes: dict[str, typing.Any]) -> None
See help(ifcopenshell.api.library.edit_library) for documentation.

Subject: [PATCH 179/429] small optimization for da1bdc802

On large projects predict dense mesh stage can take 20s+ and reusing attribute value can save up to half of this time.
Using indices also helps but it's not that significant and sometimes it's the same time as using attribute names.

Subject: [PATCH 191/429] bim.split_along_edge fixes #4675

1) description to emphasize that active object will be the one that's cutting
2) skip non-ifc elements, previously they failed to process with error `AttributeError: 'NoneType' object has no attribute 'RepresentationType'`. Also skip objects without representations.
3) add an info message at the end

Here's a short gif in case if anyone doesn't about that feature: https://imgur.com/a/338w7jx

Subject: [PATCH 194/429] Fix bcf due xsdata update #4680

After https://github.com/tefra/xsdata/commit/93a8ca0548d1f7badb628ad9fd0327672abe140b

`parser.register_namespace("xs", "http://www.w3.org/2001/XMLSchema")` started failing with `TypeError: PushParser.register_namespace() missing 1 required positional argument: 'uri'` since xsdata added a new argument `ns_map` (previously it was always using `parse.ns_map` under the hood, now it allows to provide some external dictionary). We just restore the original behaviour with internal `ns_map` by providing it explicitly.

Specified xsdata version after that change in pyproject.toml.

Also `serialize()` is now using `parser.ns_map` as a fallback value (otherwise why we do `parser.register_namespace` if we never used the `parser.ns_map`?)

Subject: [PATCH 200/429] set_element_value - pass attr value to the next part
 of the query #4495

E.g. previously set_element_value with query "material.item.Material.Name" would fail with error "Material property is expecting an IFC entity and not a string".

But now it will detect that "Material" property is not a last key in the query and will pass `.Material` value forward and try to set it's `.Name` attribute with value.

The main goal is to make sure get_element_value and set_element_value would have a same result for same queries.

Subject: [PATCH 211/429] Fix #4633. Only update the text value of the object,
 not try to be clever with types and occurrences.

Previously, we were clever in detecting types and occurrences because if you edited a type, you wanted all occurrences to be updated. Now, we no longer need to be clever because like any other UI element, the annotations shown in the active view are updated after every IFC operation.

Subject: [PATCH 217/429] fix python 3.10 loading issue after bb8e84e

The error is below.

It was failing because Callable was checking if `ifcopenshell.entity_instance` is a callable and at runtime actually it's not, it's a module.
In python 3.11 they've removed that check and therefore it's not throwing an error. Enabling forward annotations fixes it for python 3.10.
Not sure if there is a need to ensure `ifcopenshell.entity_instance` should be recgonized by python as a class at runtime rather than a module since we need it just for type checking and type checking seems to be clever enough to prioritize module classes over submodules.

Subject: [PATCH 229/429] fix bug with cost schedules confusing 0 quantity with
 no quantities

a bit related to #4704

1) fixed util.cost.get_total_quantity
2) fixed similar issue in cost.data that calculates the final value that user will see in UI
3) changed UI, "-" is shown when there are no quantities and "0" is when quantities are there but they just equal to zero.

Subject: [PATCH 230/429] cost schedule - prohibit adding multiple quantity
 types on 1 cost item

All IfcCostItem.CostQuantities supposed to use only 1 type of quantity, so they can be added up.

Changed UI to reflect that requirement - dropdown for selecting quantity type is now only visible if cost item has no quantities, otherwise it just reuses already used quantity type.

See https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/IfcCostItem.htm

Subject: [PATCH 233/429] See #4696. Allow editing of properties that do not
 comply with the pset template definition.

Strictly speaking, the only properties that should exist in a pset should be those in a pset template. However, there are situations where this is not the case, such as when the pset template has since been modified, or if there is invalid data coming from other software, or migrating between schemas. In this case, we should still load the property, and give the user the option to edit it (or null it).

Subject: [PATCH 238/429] csv to cost schedule - support more cases of 0
 quantity #4704

Before - https://i.imgur.com/CYwSGxY.png
After - https://i.imgur.com/Wbe6Ij6.png
I'll attach example .csv and .ifc in #4704

What changed:

1) If query was provided but it didn't found any elements, then it will still autoassign quantity = 0 instead of cost item end up without quantities at all (which has a different meaning in ifc). Works both with Property provided and without it.

2) If provided quantity = 0, it will now load as quantity = 0 instead of not creating any quantities at all.

3) You can provide both Query and Quantity and they all will be added to the cost item. E.g. if Quantity = 15, Query = "IfcWall", Property="Prop" and there are 3 walls in the model each having Prop = 25 then final quantity will be 15+25*3=90. Previously Quantity would take the priority and the result would be just = 15.

Though this is still doesn't work with counting quantities due behaviour in cost.assign_cost_item_quantity.
E.g. if Quantity = 7, Query = "IfcWall", Property="" (to make sure it will just count them) and there are 3 walls in the model then final quantity will be not 7+3=10 but just = 3, as query will take the priority here.

Subject: [PATCH 241/429] simpler way to check if enum property is valid
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Well, it's simpler to use but not really simpler in implementation 😅
Thanks to @Gorgious56 for helping out
Hopefully, it's a farewell to those annoying warnings

Subject: [PATCH 247/429] improve ux for assigning cost item to product types

1) also consider active object as selected when assigning / unassigning cost item to product types. Typically types are hidden and if you select some type in outliner it will become active but still not selected. Now it will be possible to add this active object without unhiding the entire Types collection.

2) info messages to make UI more responsive

That way there will be a workaround if the wall is 0.6m+ meters thick but won't have an issue when you first added a window to a thin wall and it's opening later won't work for the thicker walls.
Mentioned in #4710

Subject: [PATCH 279/429] Deprecate old material panel in the material tab and
 reimplement material duplication in the material manager

The material duplication now 1) actually creates a new blender material 2) uses the API to duplicate. One less panel outside our scene tab.

Subject: [PATCH 280/429] Deprecate old style panel in the material tab and
 port over "unlink" operator.

All the functionality is now possible with the style manager and prevents the user needing to know how Blender materials work or wrangle nodes themselves and magically have to comply with the glTF spec.

+-----------------------------
+
+In collaboration with leading UK consultancy BuildData Group (formerly Bond
+Bryan Digital), and inventor of COBie 2.4 Bill East (Prarie Sky Consulting), an
+effort was made to preserve the original IFC mapping, as well as modernise the
+mapping with the following goals:
+
+1. For anyone delivering **COBie 2.4** data using best practices from graphical
+   BIM software, there must be *no difference* between **COBie 2.4** and
+   **COBie 2.4 Legacy**. It must not contradict any specifications in the
+   official NBIMS-US and BS standards.
+2. Update compatibility to IFC4X3.
+3. Prioritise organisational data instead of personal data with discourage PII.
+4. Prioritise bSI standardised property sets over custom ones.
+5. Prevent needless repetition of data / fallback defaults that may result in
+   invalid or unexpected data in obscure edge cases.

The default is now everything is saved which should be 90% of the usecase. If you want to discard changes, there is now a button in the top right next to the IFC mode.

Now you can drag'n'drop files to Blender and they will get loaded as projects (currently there is no safe check whether current project is saved) or you can hold ALT while drag'n'dropping and link single or multiple IFC files.

Actually, it's possible to set it up that way so multiple files won't need ALT modifier (as we can't load multiple projects, only link them) but I've kept ALT modifier for that case too to avoid confusing situations.

Blender 4.1+ only as there wasn't bpy.types.FileHandler before.

Subject: [PATCH 311/429] Initial attempt at a qto module in Ifc5D

This is a more flexible, non-Blender approach to doing QTO which allows:

 - Doing QTO without Blender
 - Doing QTO using query filters
 - Using config files for QTOs
 - Choosing your calculation engine, either built-in or creating your own

Subject: [PATCH 314/429] prioritize qto base psets over other qto_ qsets after
 70a4af2 #4740

1) e.g. in ifc4x3 previously for IfcWall it would prioritize Qto_BodyGeometryValidation over Qto_WallBaseQuantities

2) It would also prioritize general Qto_BodyGeometryValidation over Qto_BuildingElementProxyQuantities.

3) removed "Qto_" check as we do qto_only in get_applicable_names

Subject: [PATCH 326/429] Continue purging tools that were specific to base
 qtos

Base qtos shouldn't be too special, it should be based off a calculation mapping. This means we can also support IFC2X3 better (which has no base qtos)

Subject: [PATCH 327/429] fix error exporting schedule of rates #4723

Issue occurred when cost item would have no quantities but had controlled objects with quantities.

1) just added a check to ensure that cost_item.CostQuantities are present
2) removed possible None return value in get_cost_item_quantity as it actually will break process_cost_data and it's never used anywhere else
3) has_changed_name was unused
4) fix possible similar issue in cost.data (though _get_object_quantities method is unused)

Subject: [PATCH 339/429] fix removing aggregate's collections (and possible
 orphaned ifc data)

Probably have met this issue before - https://i.imgur.com/EOCSGg2.png

It occurred when you would remove e.g. IfcBuildingStorey's (or other aggregate's) collection from outliner. Deletion operator removes objects first and removing aggregate's main object is automatically removing it's collection. Then it would start removing collections and will break meeting an invalid collection.

Most of the times it was scary but harmless since all collections are probably removed either way but it's critical for batch removal as it would be never finished, possibly leaving unlinked ifc data (e.g. representations and it's items) that's not removed completely until batch removal is finalized.

Traceback:
Error: Python: Traceback (most recent call last):
  File "\blenderbim\bim\ifc.py", line 360, in execute_ifc_operator
    result = getattr(operator, "_execute")(context)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Subject: [PATCH 350/429] materials ui - avoid having multiple "Uncategorised"
 categories

Previously it would create multiple same named "Uncategorised" categories for each case when Category was "", None, "Uncategorised", which was confusing and some of them ("" and None) would expand simultaneously when you would try to expand one.

Removed `or "Uncategorised"` from ui.py as there shouldn't be a need for this since all cases are handled when items are added.

Subject: [PATCH 351/429] materials ui - make expanding/contracting categories
 more natural

Previously if you had some item active before the category you're trying to expand/cotract it would jump back to that item which was confusing. Now it sets contracted/expanded category as active to prevent that jump.

Before - https://imgur.com/a/87ZDnVq
After - https://imgur.com/a/B9WOn8I

In Blender when we reload materials in collection property it's resetting scroll position in the template_list and setting it based template_list index, so the only way to preserve the scroll position is to manipulate template_list index.

Subject: [PATCH 353/429] materials ui - fix bug when it was impossible to
 contract category

E.g. it was impossible to contract category "TEST" if there was also a material with name "TEST" (and it's category was expanded). It occurred due to a mixup of materials and categories in expanded_categories.

Also changed is_expanded default value to False as it makes more sense (previous value didn't worked for materials and for categories you probably would want it to be False by default.

+    - Aggregation: a physical object is broken up into parts, or a spatial location is split into sub locations

Subject: [PATCH 383/429] specify exported api methods in __all__

It's py.types requirement, similar to 6e2edbf

Example issue without __all__:
import ifcopenshell
import ifcopenshell.api.project

# "create_file" is not exported from module "ifcopenshell.api.project"
ifcopenshell.api.project.create_file()

Subject: [PATCH 387/429] change type of exception when setting non-optional
 property to TypeError

TypeError is more correct since error occurs when user is trying to set some attribute value with None while atttribute doesn't support None type. ValueError is typically raised when provided value has a correct type but unsupported value.

Subject: [PATCH 393/429] Consider elements with openings reloading
 representations

Before - https://imgur.com/a/MMnGMBo .
Occurrences with openings wasn't reloaded if you'd change their representation items (add/remove a style, remove a representation item). Also type/occurrences representations were not always reloading.

After - https://imgur.com/a/vBDejb8

Similar thing will be added to switch representation and to representation update to solve issues like this - https://imgur.com/a/0DFIBj2 (issue is still present now).

Subject: [PATCH 411/429] Fix #4677. Fix #4809. Major improvement to local
 session offset during project loading (see description)

This improves four things:

 1. Previously, we either used OBJECT_PLACEMENT or CARTESIAN_POINT, but couldn't handle scenarios where simultaneously both the placement and the coords were rubbish for a single object. Now we offset all far cartesian points, so it consistently works and we keep track of a per-object offset.
 2. Previously, we applied the georeferencing conversion on every cartesian point which was very slow. The new method uses a simple XYZ translation which is super fast.
 3. We now use numpy which should be much faster too.
 4. Previously, objects were selectively offset based on whether they fell outside the distance limit. Now, we uniformly treat all non-geometric elements at 0,0,0 as insignificant positionally. This fixes the issue where half the model is offset and the other half isn't, but maintains the fix for situations where the site (typically) is at 0,0,0 and everything else is map coords.

Subject: [PATCH 429/429] WARNING: Remove collection syncing. The outliner no
 longer is used to change spatial hierarchy.

This is a BREAKING change (on purpose). If you want to change containment / aggregation, use the UI panels, not drag and drop on the outliner.
