Hi Mo, thanks for the tests of the Freecad surface filling module.

But yeah it does not look promising, it looks like it is afflicted by oscillations which is often a complication with this type of surface fitting calculation.

You can see them particularly in this surface:







The control points kind of wildly spike back and forth to opposite sides of the surface in a small area. This makes the surface have a kind of subtle bumpy shaping to it in those spots.

Some of the other surfaces in there are not so bad as this one but it does not really bode well for being very reliable.

There are kind of opposing forces between maintaining surface smoothness versus accuracy of forcing the surface to pass through curves. It is quite tricky to balance between these.

There will often be either oscillations or inaccurate results that aren't close enough to join up with the existing edges. Or both.

If so, make cars will be more easy here.
You could recover all users that migrate to Plasticity because of Xnurbs.
