|2D/3D CAD Systems|
Free personal edition of their commercial 3D CAD modeler. The unique feature about CoCreate is that it does not use a history based modeling philosophy. Assemblies are limited to 60 parts. Every 3 days it requires a new license, if you're connected to the internet it does this automatically, otherwise you'll have to log-in to your account on their website for the license.
