You can create a number of closed boundary curves that define small areas on surfaces. If you set the Bounding Curve parameter to Yes, you can limit the cuts to these areas. When these areas are cut, the tool center does not go past the curve.
Lines, arcs and splines can join to form the boundary curves. If the curves are not drawn on the surface, the curves are projected on the surface to form the boundary. The curves are projected in the construction view.
Use the Select Point menu to indicate the direction of the cut.
Use the Select Chain menu to indicate the beginning element.
Chain all the boundary curves and click Done.
The best performance
occurs when Maximum Feed Between is smaller
than the shortest distance between two separate boundaries, but larger
than the Step Size.
The Maximum Feed Between is on the Options tab.
The Step Size is on the Cut
Control tab.
If a flow surface is used and the surface is a trimmed surface, you
must select the bounding curves to trim the complete surface.
