Invalid Coupler


Motion analysis won't run because a joint coupler is invalid. This error can be triggered by three different causes.

Cause 1: The listed joints cannot be coupled

Click Fix to automatically change the joint type or click Review to manually change it.

Cause 2: Only one translational and one rotational degree of freedom on a single axis is allowed

Click Review and change the listed entity so that it has freedom on or about only one axis.

Cause 3: The listed entity does not have an implicit joint that can be coupled

Click Review to manually change the entity's settings in the Property Editor to make it suitable for coupling, or delete it.
