I want to suggest a feature that I think would be very useful in certain circumstances. I'm not sure it would be possible, but perhaps it is.
Currently I am developing RailClone definitions that generate parametric building podiums. I use several generators to build the walls and another set of generators to build the floors, roofs and parapets. The "wall" generators need to use a spline that has "broken", or un-welded vertices so that the segments clean up nicely at corners and are adaptive. The other generators need a closed "welded" spline in order to have a clipping area for cropping the segments. As a result, I need to use two splines (one with un-welded vertices for the walls, and one with welded vertices for the rest) and it can get a bit tedious.
I am wondering if it is possible to add an option in the generators to have it assume, or pretend that the vertices are un-welded. That way, I can create one spline that is closed and welded, but check a tick box on the generators I need to have adaptive and clean at the corners.
Attached are some images of what I am doing for reference.
