Hi Jean-Paul, probably the area of Sweep that you don't like is the "morphing" aspect of the profiles.

For Sweep, areas between profiles get a kind of blend between each profile curve, with a kind of "ease in/ease out" type stepping mechanism.

That blending method is like this:




You can see that kind of weighted blending in a sweep:






That kind of proflie to profile blending is pretty much the standard way that it is done - you'll see that same thing happen in Rhino for example.

One thing you can do to reduce it from being a factor is to also use a scaling rail, which will then kind of override the profile shaping. So for example:






Maybe in the future I'll be able to change the way the profiles are blended together to avoid that kind of stepping effect, I have some ideas. But it will probably involve re-writing some pieces of the geometry library sweep mechanism.
