[python] Re: freecad

It does seem to have gravity and more

"Users can specify constant gravity of arbitrary magnitude and direction."
I didn't see toroids in the mix, so tires might need to be layered cylinders.
There is a link to another CAD
http://www.alibre.com/xpress/software/alibre-design-xpress.asp
there, which is free for small projects, and looks like might do toroids with motion constraints. 

After Jürgen's comment, I'll think I'll go outside now...

I just found this free CAD-Software with motion simulation. It is available for Win, Linux and Mac Os. :) 
It could be useful to simulate python physics.
