Parent Object: PlanarJointMotion Defined in namespace "adsk::fusion" and the header file is <Fusion/Components/PlanarJointMotion.h>
Description
This property can be set using various types of entities that can infer a direction. For example, a linear edge, sketch line, planar face, and cylindrical face. When reading this property, it is only valid in the case where the primarySlideDirection property returns CustomJointDirection. Setting this property will automatically set the primarySlideDirection property to CustomJointDirection. The entity defining the custom direction by be perpendicular to the normal direction.
To set this property, you need to position the timeline marker to immediately before this joint. This can be accomplished using the following code: thisJoint.timelineObject.rollTo(True)
