IFC with no materials fails to load

Open simon-gd opened this issue 3 years ago • 3 comments

A simple IFC file that doesn't have properties or materials doesn't load. Since it seems to open fine in BIM Vision, I assume that the IFC is ok, but not 100% sure. Might be worth investigation Screenshot 2021-11-30 09 51 34

This zip contains two version of the model, the original (slightly larger) and a smaller one that was run through Solibri IFC Optimizer (I was hoping that would fix any IFC issues the file might have, but it didn't.

Hi, the problem is that the IFC does not contain any IFCSHAPEREPRESENTATION with the identifier "Body", so IFC.JS does not construct any geometry. -> #82=IFCSHAPEREPRESENTATION(#13,'Facetation','SurfaceModel',(#81));

If you replace "Facetation" by "Body" IFC.JS will read this geometry

Is it solved?

image By changing all 'Facetation' by 'Body' you obtain this
