I'll have to install the 30day trial. I had installed the no save version. It is hard to explain. I have an airfoil. I import the points and then make curves from the points. The leading and trailing edges are made with arcs. When I try to do a two rail sweep it won't sweep the arcs. Its ok with the splines. Give me awhile to install the other version and make a file that may help to clear it up some.

On a side note I'm having trouble with the trim. It doesn't seem to work for me. I found a work around, but just wondering why I can't get it to work.
