Ground Plane

The ground plane part adds a basic flat surface to the simulation. The surface extends out to infinity, but it is only shown graphically as a plane part. You can position the orient the plane however you want it. Unlike in V1, you can rotate the ground plane so that it is at different angles. Also, you can combine a ground plane with other types of surfaces like a terrain, or ground planes, and fluid planes. They will stack up so that when a part falls onto one it will use the one that is highest.
