Have a look at:



Face2.GetFirstLoop/Loop2.GetNext – This will give you a list of the loop boundaries

Loop2.GetFirstCoEdge/CoEdge.GetNext – This will give you a circular list of CoEdges

CoEdge.GetEdge – This will be your boundary edge

Q:
Earl，
I don’t think so. Your mentioned way was more slowly to get the boundary of face after I compared between SolidWorks API and CATIA API.

I need get the boundary of facetedFace rapidly. How to get all vertexes of facetedFace via ITessellation interface?

Do you have any suggestions?

Hello Yanhua,



Sorry about the delay on this.  You could get the tessellation of a given face by calling Body2.GetTessellation and supply that one face as part of the argument array.  The resulting tessellation would be of that face alone.  If this is not working for you, then I will need to get an idea of what the application is that you need the boundary of a given face.
