License infringement? (by Poon)
I stumbled across a 2D CAD for packaging.

http://www.rulessoftware.com/

The appearance is exactly the same as solvespace, and it uses slvs extension file.

If I recalled correctly, GNU GPLv3 requires disclosure of source as well as being released under same license. I believe this rule software is sold commercially. Is this considered a license infringement?

The interface of Sample Maker 2D looks indeed almost identical to Solvespace. And you're correct about the GNU GPLv3 license and the possible infringement. In theory it could of course also be that Solvespace is infringing the Rules Software license although the slvs extension makes that hard to believe.

May have been a scam by said Michael Collins. He took the Solvespace, customized it for a particular industry, and then...

AlphaCorr acquired Rules Software in 2008.
