You can make surfaces trimmed along isoparametric curves into untrimmed surfaces with ShrinkTrimmedSrf The ExtractIsocurve command is useful for creating trimming curves on surfaces. The ExtractIsocurve command creates the simplest possible curve exactly on the surface in u, v or both directions Note: Use the Int object snap for snapping to isoparametric curve Of the surface displays at the status bar. Is constrained to the surface, and isoparametric curve
Mesh > Extract Mesh from NURBS Control PolygonĬreates curves that duplicate surface isoparametric curves at specified locations on the surface.
It is possible to use the ExtractControlPolygon command to create polygon data that you can export and manipulate in a program that handles mesh smoothing. The ExtractControlPolygon command is useful if you want to extract control polygons as objects. This creates polylines and/or meshes that have vertices at the original objects’ control points. Of a curve, or a polygon mesh through the control points of a surface. Creates a polyline through the control points
