Best Practices for Running 3D Contact Models in MotionSolve
MotionSolve can detect and handle contact between graphic entities that represent solids.
The graphics may be defined in three ways: 
- Analytically for simple shapes such as spheres and frusta
 - As CAD geometry in their native format
 - As triangular meshes
 
Regardless of how they are created, all geometry (except for sphere-to-sphere and sphere-to-mesh contact) is eventually converted to a mesh and contact between meshes is computed during the simulation.
This section summarizes contact strategies that will help you experience successful simulation.
