Open the PointSurface_without_Joint.CATProduct document.

Automatic switch to Design mode:

If you work with the cache system in visualization mode, you no longer need to use Edit > Representations > Design Mode beforehand as the switch to design mode is automatic (an eye appears as you point the product in the geometry or specification tree). All you need to do is click.

When you create joints, you can define the mechanism within the same dialog box. Remember though, that you create a mechanism independently from the joints by selecting Insert > New Mechanism... from the menu bar.

  1. Click the arrow within the Revolute Joint icon in the DMU Kinematics toolbar (Revolute joint is the default joint type).

  2. Undock the Kinematics Joints toolbar:

  3. Select Point Surface Joint . The Joint Creation: Point Surface dialog box is displayed.

  4. Click New Mechanism. The Mechanism Creation dialog box is displayed:

    In our example, keep the default name Mechanism.1.
  5. Select Surface 1 either in the geometry area or in the specification tree.

    The current selection field box is automatically updated with your selection.
  6. Select Point 1 either in the geometry area or in the specification tree.

  7. Click Ok to end the point surface joint creation.

    The specification tree is updated.

  8. Open the PointSurface_with_Joint.CATProduct document to check your result.

It is impossible to create point surface joints if the parts involving the joint are not well positioned.
