For example, I’d like to create a “grid/mesh” of control points on a surface, move some things around, and then split or divide the surface using the control points and “lines” connecting them. I am planning to use this for a few things like walls, doors/windows, irregular curtain walls, etc. or a “cutting tool” to boolean with other objects, as shown here.
I could swear I saw some kind of split or divide command that does this but can’t find it now.
In case you would like to choose some of the available ISO’s instead of extracting the all network, the command _CurveThroughSrfControlPt may be useful.
When the rows of Cp’s are linear, you get straight lines than can then be used as Split Objects or what ever operation is wanted.
Remember that control points are only on the surface if the surface is planar. If the surface is curved most or all of the control points except for the corner points will be off the surface.
Isocurves are always on the surface. The lines between control points are generally not isocurves unless the surface is planar.
