HI
Thank's for the replies. Generally I use moi3d as a cad tool. So I design my models so that they can be manufactured. One of the methods is making flat object with a final contour in the first step and after that bending it to the final form. Sometimes it's not easy to determinate the contour or the location of other elements (like bore holes, cut-outs) of the flat object. So it would be nice if I could model the contour first and bend it afterwards, or even better do it similar to the sweep function where I can manipulate the curves an see the result on the fly.

I attached a image and the moifile.
