Tweakie,
Looks like an interesting program. I noticed that some folks asked if it can provide calc's and it does not.
Back in the day, when doing some mechanism designs at work, the program would have saved a lot of hard thinking.
Good grief I still recall the mechanism courses we had to take and all the calc's required to design the individual parts. Surely should come in handy for quick and dirty robotics stuff thus no need to do it in 3D and simulate.
