Houdini 16.5 Shelf tools

RBD Hinge Constraint shelf tool

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

On this page

This tool is useful for simulating anything that needs a hinge-like constraint, such as a swing.

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

Note

This constraint will not work with packed primitives. However, you can achieve the equivalent using a constraint network, such as the one created by the Glue Adjacent shelf tool.

Using RBD Hinge Constraints

  1. Click the RBD Hinge 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 hinge constraint and press Enter to confirm your selection.

    Note

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

  4. Set the direction for the hinge using the handle in the scene view or by setting the Constraint Direction parameters in the parameter editor.

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

Moving an RBD Hinge 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

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

  2. Click the constrained object in the scene view.
