I’ve a profile curve made to form a surface. When I offset it, it generates many more control points than seems necessary. Even after running simpliflyCurve the points remain. What is the method one uses to eliminate this?
There is no way to retain a constant offset and the same control point structure, that is why Rhino adds so many control points. You can try loosening the tolerance in Offset, but you will not have a constant offset distance as a result. Otherwise, you can rebuild the offset curve, leaving and locking the original offset, then tweak the result’s points to be “close enough”…
