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 on the object.

  1. Click Revolute Joint I_RevoluteJntP2.gif (246 bytes) in the Kinematics Joints toolbar or select Insert > New Joint > Revolute from the Menu bar. The Joint Creation: Revolute dialog box appears:

    In our example, keep the default name Mechanism.1.

    The Mechanism is identified in the specification tree.

  3. Select the Centered option button. 

  4. Select the lines in the geometry area:

    • Line 1 = hinge axis
    • Line 2 = wheel axis


  5. Select the planes in the geometry area:

    • Plane 1 = left inner hinge plane
    • Plane 2 = left wheel axis plane
    • Plane 3 = right inner hinge plane
    • Plane 4 = outer wheel plane
    The plane you select must be perpendicular to the hole axis previously selected

  6. Assign the Angle driven command if needed.

  7. Click Ok to end the revolute joint creation.

    The specification tree is updated.
