Fabrication ductwork generates hundreds of duplicate IfcElementTypes

6

I'm noticing a lot of fabrication models have a lot of IfcElementType classes with an identical "Tag" (i.e. Revit element ID). Each element type only has a single occurrence. This...

Revit should export colour information associated to IfcMaterial where possible

1

Revit seems to want to export colour information using `StyledByItem` (See Geometry presentation assignment in the below chart), whereas although this makes sense in a small subset of scenarios (e.g....

ENH: Customise spatial hierarchy

### Enhancement Description Revit's spatial hierarchy seems to be hardcoded to IfcSite > IfcBuilding > IfcBuildingStorey. A large number of the projects I work on have multiple sites and multiple...

Revit shows `PLAN` GeometricRepresentationContext items in 3D view

This is the URL the popup has after I click the yellow `Click here to authorize application` button.

IfcSystem has two duplicate inverse attributes ServicesFacilities and ReferencedInStructures

1

Both have the exact same data type (and therefore contents?): ``` SET [0:?] OF IfcRelReferencedInSpatialStructure FOR RelatedElements ``` Should ServicesFacilities be removed?

Revisiting this as we are working on mapping data required by state government to IFC. There are lots of ambiguities with IfcLightFixture and IfcLamp - for example, how are they...

Am I missing something, or is there currently no way to store the rated electrical output (peak kW) of solar panels / PV systems? Maybe a new property RatedPowerOutput in...

4.1.4.1.4 Spatial Composition does not cover CompositionType for facility parts

3

CompositionType allows a spatial element to be decomposed into another element of the same class. For example, IfcBridgePart[COMPLEX] -> IfcBridgePart[ELEMENT]. However, this combination is not listed for the newer IfcFacilityPart...
