IfcClash
========
This documentation is free software! You are free to contribute and help write
this document.
IfcClash is both a CLI utility and library that lets you perform clash detection
on one or more IFC models. Clashes are defined in terms of clash sets with
filters using the IFC query syntax.

Source installation

Indices and tables
------------------
1. :doc:`Install IfcOpenShell <ifcopenshell-python/installation>`
2. `Install hppfcl <https://github.com/humanoid-path-planner/hpp-fcl>`_
3. Optionally `install bcf <https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.7.0/src/bcf>`_ (needed for BCF reports of results)
4. `Clone the source code <https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.7.0/src/ifcclash>`_.
5. ``cd /path/to/src/ifcclash``
* :ref:`genindex`
* :ref:`modindex`
* :ref:`search`
Here is a minimal example of how to use IfcPatch as a Python module or CLI
utility:
::
$ python -m ifcclash -h
usage: __main__.py [-h] [-o OUTPUT] input
Clashes geometry between two IFC files
positional arguments:
input A JSON dataset describing a series of clashsets
options:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT
The JSON diff file to output. Defaults to output.json
Instructions on what clashes to perform are structured in terms of clash sets.
Each clash set contains instructions of collisions that we want to perform, and
can be named so it is easy to distinguish. A typical name would be "Structure
and Pipes", to describe that we are are detecting collisions between structural
elements and pipes.
Each clash set may include two groups of objects, named ``A`` and ``B``. This
tells IfcClash to attempt to find collisions between any object in group ``A``
with any object in group ``B``. Group ``A`` is mandatory, but group ``B`` is
optional. If group ``B`` is not provided, IfcClash will detect all clashes
within objects of group ``A``.
Within group ``A`` or ``B``, you may define one or more data sources of objects.
A data source must include a path to the IFC file which the objects come from.
You may also optionally provide a filter to only include or exclude certain
objects. If no filter is provided, then all objects will be used to detect
collisions.
Here's a sample JSON description of a single clash set, with both groups
defined with data sources.
.. code-block:: json
[
{
"name": "Clash Set A",
"a": [
{
"file": "/path/to/one.ifc"
}
],
"b": [
{
"file": "/path/to/two.ifc",
"selector": ".IfcWall",
"mode": "i"
}
]
}
]
Once your have your JSON description of your clashes, usage is like any other
CLI app.
::
$ ifcclash clash_sets.json
$ cat output.json
Here is a minimal example of how to use IfcClash as a library:
.. code-block:: python
import sys
import json
import logging
import ifcclash
settings = ClashSettings()
settings.output = "output.json"
settings.logger = logging.getLogger("Clash")
settings.logger.setLevel(logging.DEBUG)
handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.DEBUG)
settings.logger.addHandler(handler)
ifc_clasher = Clasher(settings)
with open(args.input, "r") as clash_sets_file:
ifc_clasher.clash_sets = json.loads(clash_sets_file.read())
ifc_clasher.clash()
ifc_clasher.export()
You can also alias it to a command:
::
$ alias ifcclash='python -m ifcclash'
Alternatively, you can package it as an executable.
::
$ python make.py
$ ./dist/ifcclash

External classification systems such as Uniclass or Omniclass are
ways of categorising elements in the AEC industry, typically
standardised or nominated by governments or companies. A system
typically contains a series of hierarchical reference codes and labels
like Pr_12_23_34.
Classifications may be applied to many things, not just physical
elements, such as doors and windows, spatial elements, tasks, cost
items, or even resources.
Prior to assigning classificaion references, you need to add the name
and metadata of the classification system that you will use in your
project. Classification systems may be revised over time, so this
metadata includes the edition date.
Common classification systems are provided as an IFC library which may
be downloaded from https://github.com/Moult/IfcClassification for your
convenience. It is advised to use these to ensure that the
classification metadata is standardised.
Adding a classification system will not add the entire hierarchy of
references available in the classification. References need to be added
separately. Typically, you'd only add the references that you use in
your project, see ifcopenshell.api.classification.add_reference for more
information.

all metadata is added correctly.

"""Adds a new classification reference and assigns it to a product
A classification reference is a single entry such as "Pr_12_23_34" that
is part of an external classification system (such as Uniclass or
Omniclass).
References can be added to almost any object in IFC, including physical
objects, object types, properties, tasks, costs, resources, or even
resources such as profiles, documents, libraries, and so on.
Classification references can be added in two ways. Option 1) specify a
custom arbitrary reference, where you have the manually specify the
identification (e.g. "Pr_12_23_45") and name (e.g. "Door Products").
Option 2) add a reference from an IFC classification library. The latter
is preferred if you are using a common classification system such as
Uniclass, as the library will be prepopulated with all the valid
classifications already.
Objects are allowed to have multiple classification references from
multiple classification systems. This means that adding a new reference
will not remove existing references.
References can be inherited from types. This means that if an
IfcWallType has a classification reference of Pr_12_23_34, then all
IfcWall occurrences of that type automatically get the same
classification of Pr_12_23_34. This means that it is more efficient to
assign to types where possible. If a classification reference is
assigned to both the type and an occurrence, then the assignment at the
occurrence will override the type classification.
:param product: The IFC object, property, or resource you want to
associate the classification reference to.
:type product: ifcopenshell.entity_instance.entity_instance
:param reference: The classification reference entity taken from an
IFC classification library. If you supply this parameter, you will
use option 2.
:type product: ifcopenshell.entity_instance.entity_instance, optional
:param identification: If you choose option 1 and do not specify a
reference, you may manually specify an identification code. The code
is typically a short identifier and may have punctuation to separate
the levels of hierarchy in the classificaion (e.g. Pr_12_23_34).
:type identification: str, optional
:param name: If you choose option 1 and do not specify a reference, you
may manually specify a name. The name is typically human readable.
:type name: str, optional
:param classification: The IfcClassification entity in your IFC model
(not the library, if you are doing option 2) that the reference is

:param is_lightweight: If you are doing option 2, choose whether or not
to only add that particular reference (lighweight) or also add all
of its parent references in the classification hierarchy (not
lighweight). For example, adding a lightweight reference to
Pr_12_23_34 will only add Pr_12_23_34, but adding a heavy reference
to Pr_12_23_34 will also add Pr_12_23 and Pr_12. These parent
references merely help describe the "tree" of classifications, but
is generally unnecessary. Using lightweight classifications are
recommended and is the default.

"""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

A cost item may have construction resources (e.g. equipment, material,

the cost item, or assigned first to a task, and the task is then
assigned to the cost item.
The cost of a resource is calculated by the total sum of all of its base
costs. If no quantity is provided, that sum is considered to be the
total cost. Otherwise, it is considered to be a unit cost, and is then
multiplied by the resource quantity. The quantity is either stored as a
base quantity (such as a volume) for a things like material resources,
or as a duration as a daily rate for labour resources.
The final calculated cost is set as the cost item's value. Any
previously existing values are removed.

Certain objects are typically "axis-based", such as walls, beams,
and columns. This means you can represent them abstractly by simply
drawing a single line either in 2D (such as for walls) or 3D (for beams
and columns). Humans can understand this axis-based representation as
being a simplification of a layered extrusion or a profile that is being
extruded along that axis and joined to other elements.
Using an axis-based representation makes it easy for users and computers
to analyse connectivity and spatial relationships, as well as makes it
easy to parametrically edit these objects by simply stretching the start
or end of the axis.
For now, only simple straight line axes are supported, represented by a
start and end coordinate. The order is important. For walls, the start
must be at the minimum local X ordinate, and the end at the maximum
local X ordinate. For beams and columns, the start is at the minimum
local Z ordinate, and the end of the maximum local Z ordinate. The first
coordinate is the "start" and the second coordinate is the "end". This
stat and end is then used to determine any parametric junctions with
other elements.
Using an axis-representation is optional, but highly recommended for
"standard" representations of walls, beams, columns, and other
structural members. A rule of thumb is that if you can draw it as a line
on paper, you can probably represent it using an axis.
