Tesselation/CGR Details from CATPart_CATIA_API

I need to read the tessellation/cgr/visualisation details from a CATIA V5R18 Part file using CATIA V5R18 API.

Visualisation details such as:

  1. Number of Vertices
  2. Number of Triangles
  3. Number of Strips
  4. Number of Fans
  5. Number of Normal
  6. Bounding Sphere Centre and Radius

These details I have read from .cgr files using CAT3DRep/CATRep/CATSurfacicRep, but I am not able to read the same for .CATPart files.

From .CATPart with the help of CATIVisu I got CAT3DBagRep type, when I queried from PartFeatures. But to get Visualisation details I need CATSurfacicRep.

What interface should I query and from where should I query?

I am not sure about R18 but for R22 and R23 if you have the CAA documentation there is an example located at: C:\Program Files\Dassault Systemes\B23\CAADoc\CAATessellation.edu. This example code has everything you need to get the tessellation data except normals and bounding spheres. I used this example code when I was teaching myself how to make a tessellated nurbs surface and it was quite useful for testing.
