looking for some help/pointer(s) closing an object with complex edge surfaces. starting with a water tight object, I “milled” a slot in the object’s model leaving a “naked closed edge”. haven’t not found a “close it” tool! a surface patch from 4 edges looks promising but don’t know how to extract the “curve” from the surface model which is a must given its non-standard form……. any help or thoughts on how to proceed would be greatly appreciated!!
