Body Constraints Form

A Body Constraint causes all of its constrained joints to move together as a three-dimensional rigid body. By default, all degrees of freedom at each connected joint participate.  A subset of the degrees of freedom can be selected to be constrained.

This constraint can be used to:

The constraint must apply to at least two joints to have any effect on the model. These joints may have any arbitrary location in space.

Use the following areas on the Body Constraints form to make the appropriate entries:

If the Advanced > Define > Joint Constraints command was used to access the Body Constraints form, the defined constraint must be assigned to the joints.

 

Access the Body Constraints form as follows:

 

Click the Advanced > Define > Joint Constraints command to display the Define Constraints form, or select the joints to be constrained and click the Advanced > Assign > Joints > Constraints command to display the Define/Assign Constraints form. Then do one of the following:

    • Select "Body" from the Choose Constraint to Add drop-down list and click the Add New Constraint button.

    • In the Constraints display list highlight a previously defined Body constraint and click the  Modify/Show Constraint button.
