[IFC-Viewer] Some IFC-Viewer do not support IfcCsgSolid with Cylinder and Cone. Why?

edited March 2023 in General

So there is this ifc file from bSI https://github.com/buildingSMART/Sample-Test-Files/blob/master/IFC 4.0/BuildingSMARTSpec/geographic-referencing.ifc

Here is this file opened in XBim Xplorer:

Also those IFC-Viewer could open it:

  • FreeCAD
  • BlenderBIM
  • BIMCollabZoom
  • CAD Allplan

Those that could not open it:

  • Solibri
  • BIMVison
  • Dalux
  • ACC
  • Navisworks Manage

I am not sure what the problem is, even if the ifc entity exits since before IFC2X3. Here below links to the IFC2X3 documentation.

IfcCsgSolid
https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifcgeometricmodelresource/lexical/ifccsgsolid.htm

IfcRightCircularCylinder
https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifcgeometricmodelresource/lexical/ifcrightcircularcylinder.htm 

IfcRightCircularCone
https://standards.buildingsmart.org/IFC/RELEASE/IFC2x3/TC1/HTML/ifcgeometricmodelresource/lexical/ifcrightcircularcone.htm

Is there still a way to see it in all the ifc-viewer?
