Use relations on mates to constrain degrees of freedom between mates.

Types of relations

Onshape currently offers these types of relations:

  • Gear Relation - Relate two mates with revolute degrees of freedom
  • Rack and Pinion Relation - Relate a mate with rotational degree of freedom to a mate with linear degree of freedom
  • Screw Relation - Constrain the rotational degree of freedom in one cylindrical mate to the translational degree of freedom in the same cylindrical mate
  • Linear Relation - Constrain the linear motion between two mates to change at a constant ratio
