I tried a program out called GrabCad, compatible with a lot of ADesk 3D stuff. Didn't like it or need it so I deleted it..
Since then I've recieved a lot of emails from this company, I've used thier unsubscribe feature many times, they've tried to call me, they've sent me more emails...
I'm still working on some way to make it all stop.
If you use it and like it, more power to you. I'll never touch anything associated with this product or company ever again.
It should be called GrabYourEmailAndNeverLetGo but that would be too hard to remember..
