unit.h and geolocation.h both include ../ifcparse/express.h for the entity
walking they do, which puts the whole module out of reach of anything that
cannot link IfcParse. Most of what a viewer wants from them needs no IFC at
all: the unit conversion tables, and the Helmert parameters-to-matrix math.
Move those into unit_convert and geolocation_transform, and build them as a
new helpers_math target that `helpers` re-exports PUBLIC, so existing callers
keep working through the unchanged unit.h / geolocation.h includes. The new
target has no IfcParse or Qt dependency and so builds under Emscripten, where
the rest of this directory cannot.
One target rather than compiling the sources into each consumer: the glob in
this directory would otherwise put them in libhelpers.a as well, leaving two
copies of the same objects in any link that pulls both.

Follow-up to the scalar-only fix in #8754, per aothms's direct request on
that PR ("Please do make all int types consistent") and his own original
2023 design intent on issue #3058 ("make all integers (incl. schema
namespaces) an int64_t"). Widens the remaining inconsistent spots now that
compatibility isn't a constraint on this v0.9 branch:
- Integer aggregates (IfcTriangulatedFaceSet.CoordIndex and similar
List<int> attributes), including the SWIG to_vec_int/to_vec_vec_int
helpers, which previously silently truncated via static_cast<int> on the
Python-set path - the same bug class as the original scalar issue.
- The schema code generator (express/mapping.py's integer type mapping),
and all 12 generated schema header/source pairs regenerated to match, so
every schema-typed getter/setter (e.g. IfcOwnerHistory::CreationDate) is
int64_t end to end, not just the dynamic attribute-value path.
Instance/reference identifiers (STEP #123 ids) are deliberately left at
32-bit: they're a file-local index into internal maps, not an EXPRESS
domain value an application chooses, and no realistic STEP file has
billions of entities. The lexer's Token_IDENTIFIER parsing still funnels
through a 32-bit int for this reason - flagged as a known, low-risk gap
rather than fixed, since fixing it would mean touching indexing/hashing
code for no realistic benefit.
Verified: original PR's round-trip tests extended with aggregate cases
(IfcTriangulatedFaceSet.CoordIndex, InnerCoordIndices) at 64-bit boundary
values, in memory and through STEP text, IFC2X3 and IFC4. A standalone C++
program exercising the generated schema API directly (Ifc4::IfcOwnerHistory
::setCreationDate/CreationDate, IfcTriangulatedFaceSet::setCoordIndex/
CoordIndex) confirms int64_t end to end, bypassing SWIG. Full build
(BUILD_IFCGEOM, WITH_OPENCASCADE, BUILD_IFCPYTHON, IFC2X3+IFC4) clean.
test/util/test_attribute.py and test_file.py pass unchanged.
This contribution was produced with the assistance of an AI coding tool.
- helpers/placement: port get_storey_elevation (placement Z, falling back
to the Elevation attribute), matching ifcopenshell.util.placement.
- Add a secondary column: the storey elevation for IfcBuildingStorey,
otherwise the LongName when filled. Elevations are right-aligned.
- Columns: Name is drag-resizable (interactive) and defaults to 20% of the
width, Long Name stretches to fill the rest, and the eye is pinned to the
right at a fixed width. Header shown so the divider can be grabbed.

Build the spatial hierarchy panel from the loaded model's real IFC
spatial structure instead of mock data:
- helpers/element: add get_spatial_children (IsDecomposedBy -> RelatedObjects,
filtered to spatial elements) to walk IfcProject -> IfcSite -> IfcBuilding
-> IfcBuildingStorey -> IfcSpace.
- SessionState: relay dataSourceReady as modelDataSourceReady (the .ifc for a
sidecar hit loads asynchronously, so the tree can only build once it arrives).
- spatial_hierarchy/View: walk the active model's IFC file into a TreeNode
tree, naming nodes by Name (fallback to class), mapping site/building/storey
kinds; siblings sorted with natural (numeric) collation.
- spatial_hierarchy/Panel: tree now fills the panel height (setBodyExpanding +
Expanding size policy); right-click menu for recursive Expand/Collapse
Subtree and Expand/Collapse All.
Add the concept of an active model:
- SessionState: activeModelId / setActiveModelId / activeModelChanged; the
first loaded model is active by default; reassigns/clears on removal.
- Models panel: clicking a model makes it active; its cube icon is drawn with
the accent colour (makeAccentSvgIcon) via FederationItemModel::setActiveModelId.
- The spatial hierarchy reflects only the active model.

Add helpers to src/helpers/element: get_scalar_attributes (primitive
EXPRESS attributes only — entity refs / aggregates omitted), get_type
and get_container (ports of ifcopenshell.util.element), and a public
get_string_attribute for safe by-name reads.
Wire them into the properties panel:
- Attributes section shows the element's direct primitive attributes for
live entities, or cached GlobalId / Name for geometry-only elements.
- Relationships section shows the construction Type and spatial Container
by name (falling back to the class when unnamed).
- Placeholders are cleared once a project is loaded, so no mock data leaks.
Also: a deselect (click on empty space -> object_id 0) no longer resets
the panel; it keeps showing the last active object. Project reset/open
still clear it.

Add src/helpers/element.{h,cpp}, a schema-dispatched C++ port of
ifcopenshell.util.element.get_predefined_type: prefers the associated
type element's predefined type (IsTypedBy / IsDefinedBy), falls back to
ElementType / ProcessType when USERDEFINED, then the occurrence's own
PredefinedType / ObjectType. Attribute reads are by-name so they work
across the IfcElement / IfcType* subtypes that carry these attributes.
Wire it into the properties panel entity summary: live IFC entities show
their real predefined type; geometry-only elements (a .ifcview loaded
without its .ifc/.rdb) show "N/A". Clears the placeholder so a stale
predefined type no longer leaks once a project is loaded.
