IFC4 Export: Tesselate / triangulate everything.

Hello everybody Smiley (fröhlich)

 

I need to know if it's possible and if yes, how to export Revit-Models into an IFC4-File with every geometry tessellated/triangulated, so that the IFC4-File contains for every object the vertices and faces (and may normals). The structure of IfcTriangulatedFaceSet ist perfect for what I need.

I want to take the vertices and faces of the objekt to process them further.

At the moment I can only export to IFC4 and the file contains too many complex information like ExtrudedAreSolid, RectangleProfileDef, BReps, Splines etc.

 

So to imagine a concrete case: If someone creates a Wall with a 90° Corner by using 3 Points, a spline and then he Extrudes this Wall. The exportet IFC4-File contains this comlplex information but no vertices of the wall's faces. It would be nice to export the Modell and to get the vertices-coordinates.

 

Greeting Smiley (fröhlich)
