I was working with the Clipping Plane function and thought having the ability to create a Section curve while in Clipping Plane would be useful, might be a part of section tools. This is a function within PowerShape that I found useful.
Hi Dave- this will be in V6. For now, I can’t remember if SecionTools has anything in it but you can use the ClippingPlaneCurves script from here:
