Please add a license

Please add a license so I can consider adding three.cad to the wiki.osarch.org software directory.

I suggest a copy left reciprocal license like GPL 2 or 3

Hi, have you considered adding a license to evaluate commercial use? It still needs some features but without a license it is too risky to further develop.

@DuncanLithgow apologize for the delay. I was forced to use a GPL 3 license because the app links to this project
