Hi there!
I have a question on how to handle cut-fill for elements in my ifc file. My ifc file comes out of a modeler that makes a mess and doesn't assign correct ifcClass to elements.
In my case I have a cut to create a "river" and a location where this volume will be placed.
In my IFC I only have these two surfaces (not solid) and the original DTM is not exported (atually I can add it as a surface).
I've discovered about IfcFeatureElement which contains fills but from what I understand you need the original DTM and create a volume (I've surfaces) and apply that element as a cut (IfcEarthworksCut) or fill (IfcEarthworksFill).
I've assigned IfcGeographicElement to my surface and will add some Pset properties. Is this the right way to do it?
Thanks!
Dennis
