There is a way to reduce points from this surface?
I don’t know why but ShrinkTrimmedSrf don’t shrink this points.
I need to export to IGES and use in a cam software, but it is so heavy that the cam software don’t even open 
And this is only one of many surfaces
I would use the ! _Split command with the “Isocurve” and “Shink=Yes” options on about 20 different areas of the surface, then repeat that on the opposite direction with another 20 splits. Then, I would apply ! _ShrinkTrimmedSrf to the newly split small surfaces. That whould reduce the total control point count by about 3-5 times.
