Speckle Viewer Not Showing IFC Slab

I noticed that the speckle viewer was not displaying the IfcSlab objects in my scene. I’m able to reproduce with a slab with an edited profile in a minimal IFC file.

In 3dviewer.net it displays properly:


Hey @zicklag could you share the URL with the project you uploaded the IFC to?

Hi @zicklag

I’ve taken the .ifc file you shared and uploaded it to speckle: Viewer - IFC Slab - Speckle

I had a look and it seems the geometry for the slab is invalid. This makes me believe it is a parsing/converting issue. We’ll have a closer look and hopefully get to the bottom of it
