Advanced Joints panel - Connectivity tab for a ConstraintMate Joint

The ConstraintMate joint - Connectivity tab defines the general mating type of constraints between two bodies.  There is a variety of types of constraints which are available under this category, however these can be broadly categorized under the following three types:

advjnt_constraintmate_conn_tab_drp_dwn_menu

Distance
Coincident
Tangent

Each constraint type further provides various geometric methods to constrain one body with respect to the other body.  For example, a general mating constraint type of Distance can be defined between two bodies (Body 1 & Body 2) in order to ensure that a constant distance is maintained between a point on Body 1 with regard to a line on Body 2.  In this case, select Point from Geometry 1 drop-down menu and Line from the Geometry 2 drop-down menu.

Note        The corresponding MotionSolve argument under the Constraint_Mate statement is DIS_POI_LIN.

The table below summarizes the various combinations of Geometry choices along with the keyword TYPE that is written to the Constraint_Mate statement for MotionSolve:
