There is some discussion in archives on this CAD program so somebody may be able to help.

I downloaded a few free CADs, then found Siemens Solid Edge 2D. I've found it really easy to use.

Imagine a rectulangar piece with a number of equal "sine wave" type curves, joined by tangent lines, along the top edge. The piece has square sides and base. Like a ruler with wavy lines on one long edge only.

I need to be able to STRETCH it to a number of different lengths - in the horizontal dimension only, retaining the existing vertical dimension. The piece will retain the same number of curves, but stretch them all equally. The radius of the curves will remain the same, the arc distance increases. as does the length of the tangent lines.

There is a tool where the piece can be stretched, but only by lengthening one selected part within it.

I've hunted through the program, but can't find anything. So if anybody can help, it would be really appreciated.
