Taking a look at Sweep again

[optigon]

There might be something I can do about aligning the sweep axis in most cases; I'll take a look.

I will try explaining the modification I want to make to Sweep by using Sweep Free as the example.

Sweep|Free uses the camera position to determine the Sweep Axis. Each time the camera moves the plane of the Sweep Axis changes. Try it and you will see.

I propose to replace the Sweep Rotation mouse button option with an option to rotate the Sweep Axis.

I may be wrong, but I think it will give the user better control for organic modeling.
I also believe that it will still be possible to make twisted seashell shapes using Repeat D args, even though the twist happens at the base.

Let's give it a try and see though.
