Creating Mechanical Joints 

This task shows you how to create a mechanical joints.
A mechanical joint represents the translations and rotations that are allowed or not between two assembly components, or between an assembly component and a support.
During the analysis, only the translations and rotations not allowed are taken into account.
It is not possible to create two mechanical joints at the same location.
See also Setting Parameters as Default to instantiate a mechanical joint.
Open the BasicTaaProcess2.CATProcess document.

  1. Click the Mechanical Joint .

  1. Select the Plate Two assembly component as the first element to create the mechanical joint.

    The Mechanical Joint Definition dialog box appears.
    Eleven types of mechanical joints may be defined according to the axis definition of the mechanical joint :
