This free download:
Is available to any active maker, CAD enthusiast, or design challenge competitor interested in using CAD to bring their ideas to life.
Is intended for personal use, and may not be used for commercial purposes
Has a license that does not expire
Note: Files created in this edition cannot be opened in commercial versions of Solid Edge and 2D drawings are watermarked, but your designed parts and assemblies can be 3D printed so you can easily create prototypes.
I don't think OS CAD has anything to do with it, IMO.
