Use bushings to create connectors or constraints with specific degrees of
freedom.
Select bushing type.
Bushings connect two parts together. Grounded bushings connect a
single part to a fixed point.
Set stiffness values to either 0 (free) or Rigid.
Note: The directions in the Stiffness tab
reference the local coordinates for each bushing, not the global
coordinate system. You can change the global coordinate system in
the Coordinate system tab.
Use enforced displacement to create constraints with specific degrees of
freedom.
Set displacement to 0 to constrain all displacement in specific
direction(s) on faces.
