Hello,

Could you please tell me how you solved it? Is there an Open Cascade function that already exists to compute the centroid of a face?

I know how to compute the centroid of a polygone, but not when some edges are circles, ellipses, and so on.

Answer from anyone would be appreciated. Thanks

Miguel

I'm not sure, but i think you may try using the triangulation. The polygonOnTriangulation gives you the aproximated linear polygon of any surface.

You could try calling BRepGProp::SurfaceProperties and then get center of mass. This is a general approach for any type of geometry.

Thanks a lot.
The two approachs work well. Thank you guys, it's very nice of you.
