Is there somewhere that would tell me How you would do sweep in 2 portions with diiferent params for each?
Is this the second rail thing? Or, how is the second rail used?

I think this is what the original thread was getting at and I would like to know also.
Thanks.

Also, I think this is what was confusing me before. In the Carrara program, they have a sweeping tool that does the scaling rail, also with symmetry (your keep height check) and they ALSO do the cross-section lofting in the same area. Yours is split into 2. (yet dual functionality in both. sweet!)
