Hi
I have a face with a hole. I need to sample the surface with points. My problem is that if I use IUVSurface_DG.GetPoint(uv) and uvs are evenly sampled in the IUVSurface_DG.GetRanges().GetRange(0 and 1) the points cover the hole also. I need sampling of the face only.
What is the way?
Thanks

Re: Sampling of a surface
Hello
Ranges of a face are basically ranges of the surface which defines geometry of the face. This includes the hole. Holes means there is a curve in uv parameters which excludes the related curved polygon out of the ranges rectangle.
Unfortunately, there is no way currently to check if a uv is inside the trimmed area or not. You could use the method described in the Point to face projection thread. If a uv point has distance greater than a tolerance (e-4 should be enough) it means the uv point is outside of the trimmed area and the 3D point is outside of the face.
