Creating a Mechanism and Revolute Joints

This task shows you how to create a mechanism and revolute joints.

Open the rods.CATProduct document.

  1. Select the product in the specification tree, then select Edit > Representations > Design Mode.
    Now, expand the tree to show all the design components of the product.

  2. Click Revolute Joint I_RevoluteJntP2.gif (246 bytes) in the Kinematics Joints toolbar.
    The Joint creation : Revolute dialog box is displayed:

  3. Click New Mechanism. The Mechanism Creation dialog box is displayed:
    you can now enter a name of your choice. Click Ok when done.
    In our example, keep the default name Mechanism.1
