We work with fairly big meshes in Rhino/Grasshopper and have noticed that on some meshes the IFC-object is missing faces. It seems that there is a limit of about 23 000 faces? Where does this limit come from, is it intentional from you, limit of IFC-standard itself or a bug?
We have tried creating the IFC-objects with components FaceBasedSurfaceModel, TessellatedFaceSet and ShellBasedSurfaceModel which all create the same result. What are the differences of these components anyway, is the geometry always the same but the IFC type different?
We are using Rhino 7 and ggRhinoIFC version 220.127.116.11 from Package Manager, but the problem exists with earlier versions of ggRhinoIFC too.
