Need help with custom element tweaks

[Philippe Hurbain]

Both parts look good to me, in LDView and in MLCad...

I can't seem to figure out how to use MLCad to scale a primitive visually and I haven't understood the algorithm to calc the rotation matrix for rotations and scaling. Any tips?

I am afraid that there is no other method than the one I described here - granted, it hardly qualifies as "visual"!!!
