Hi Michael.

Thanks a lot for the suggestion.

But...I think that the method you mentioned is not right for me.

Because this part of the sentence " if any start/end points match between the curve segments and the hole edges" it's too restrictive.
I could have more than one curve that shares the same start/end point but with different shapes.

For example :



Furthermore also this part of the sentence is not what I want to do : "...remove those then send the rest to planarsrf to generate loops."

Because I want to use my script to find not only "totally enclosed curves" but also "partially enclosed", that is the curves that intersect the boundary of
the "container".


I really don't know.

Maybe for the moment I can continue to use "Project" with "ClosestPt" and for the moment not to take into account the rare cases where it fails .

Or I can decide to witch to "Direction" mode and for the moment restrict the scope of my scripts to "TOP plane only", that also was the original idea.

I don't know.

Have you got a final suggestion to give me about these considerations ?

Thanks a lot :)
