Perpetual License CAM

Not important, it just does not belong here, only Open Source stuff does.
I allowed it at my own risk, to help you till you set up your own website and forum.
I have yet to figure out if it would be OK to present it in the "CAD/CAM" section after your site is up and running. Either way, support must be on your side, not on ours.

Do not delete your replies, that is really, really not polite.
If you do need to edit it, leave the original content, unless it poses a risk/danger, and add the corrections/additions/etc.

I understand, in that case you can delete it. If some customer posts a question in future in a different thread, I will reply, but no more promotion and I'm also grateful for the opportunity the forum provided. We really wish we could go open source. We will at least make some of the larger suite of products open source. Our target is to make engineering software of all kind extremely affordable.
