Changing range affects generated mesh

[GameJazz]

Hi
No plans to do so, because doing so will go against other constraints. For example, imagine someone sets a constant mesh resolution of one polygons row every meter, then sets the length of the partial extrusion to 1.5 meters (out of a 2 meters spline). The 2nd row will be only half meter long. If the extrusion is on the full spline, the second row will be 1m long, and will not match the shape of the 0.5m long row. If we apply what you suggested, the shapes will match, but the total extrusion will have 3 rows, the first one of 1m length, and the two other of 0.5m length each, breaking the constraint of having 1m long rows.
I hope my explanation was clear.

Correctly me if I am wrong, but I don't think it would violate the other constraints? If my understanding is correct, instead of basing the full extrusion on the partial extrusion, we can base the partial extrusion on the full extrusion. For example, in this image, black is the full extrusion, blue is the current implementation of a partial extrusion, and red is what I am hoping to get for the partial extrusion. It is based on the full extrusion.
