Lock Part

Use the Lock Part command to create, edit, and delete assembly constraints between connected ports. Locking parts assures that components remain attached. For example, you can lock the clocking angle of a part so that the angle remains constant.

Assembly constraints

You can use several constraints with the port to port assembly constraint. The Lock Part dialog box allows you to create these constraints when Assemblies Constraints are active.

The Lock Part functionality has been modified to reflect the functionality available in the Assemblies Constraints dialog box. The constraints are bidirectional.

Building constraints

The behavior for the non-DCM3 and DCM3 version of Lock Part; the operations below also apply to the Place Part dialog box, which builds mating conditions (and now Assemblies Constraints) to parts placed onto other parts:

Operation	Mating condition	Assembly constraints
Lock Engagement	Port → Port Engagement Mate	Touch constraint between the two ports. Parallel constraint between the alignment vectors of the two ports.
Lock Rotation	Port → Port Rotation Mate	Touch constraint between the two ports. Parallel constraint between the alignment vectors of the two ports. Parallel constraint between the rotation vectors of the two ports.
