RBD Pin Constraint

Constrains an object to a point in space using a pin-like connection.

See also: RBD Object, RBD Hinge Constraint, RBD Spring Constraint, RBD Angular Constraint 2 more , RBD Angular Spring Constraint, Parent Constraint

This tool can be used, for example, to simulate something swinging from a point. For example, a pendulum swinging or a tire swing at a park.

You need to create an RBD object to apply this constraint to before you can use this tool.

Using RBD Pin Constraints

  1. Click the RBD Pin Constraint tool on the Rigid Bodies tab.

  2. Select the object to constrain and press Enter to confirm your selection.

  3. Select the position for the pin constraint and press Enter to confirm your selection.

    Note

    You can hold Alt to detach the constraint from the construction plane.

For specific parameter help see the RBD Pin Constraint dynamics node help.

Moving an RBD Pin Constraint

  1. Click the Dynamics Select Mode button on the selector and handle controls toolbar.

  2. Click the constrained object in the scene view.

  3. Click the Dynamics Select Mode button and turn on the Dynamics Modifiers checkbox.

  4. Click the constraint you want to edit and press Enter to display the transformation handles.

Switching to the dynamics level
