Converting Assembly Constraints to Joints Reference

Automatically create standard joints from assembly constraints.

Note: When Automatically Convert Constraints to Standard Joints is active, you can still manually add spatial joints. You cannot convert assembly constraints for one joint at a time.

Access:

Ribbon: Dynamic Simulation tab Joint panel Convert Constraints

The rules for adding a joint are the same as the rules for the Insert joint feature. If the child component is grounded and has no constraints, an open kinematic loop is created. If the child component is grounded and already joined with another grounded component, a kinematic loop is closed.

Select two parts	Specifies two components so the software determines which constraints between the two components can be converted into standard joints. Only assembly constraints between the two components appear in the Mates field. The first component selected is the parent component . The second component selected is the child component. The existing assembly constraints between these two components appear in the lower part of the window.
Mates	Display the mate constraint between the two components and specifies which to use in creation of a standard joint.
Joint	Displays the type of standard joint, including an animated illustration, that the software can create from the selected mate constraints. If no mate constraints are selected, the software creates a spatial joint (six degrees of freedom), by default.

The following table indicates standard joints and the various assembly constraints that the software can convert into them.

Joint	Constraints
Revolution	Insert (circular edge, circular edge) Mate (line, line) and mate (plane, plane) perpendicular to offset or not Mate (cylindrical face, cylindrical face) and mate (plane, plane) perpendicular to offset or not
Prismatic	Combination of two mates (plane, plane) that are not parallel
Cylindrical	Mate (line, line) Mate (cylindrical face, cylindrical face)
Spherical	Mate (point, point) Mate (spherical face, spherical face)
Planar	Mate (plane, plane)
Point Line	Mate (line, point) Mate (line, spherical face) Note: The central point of the sphere remains in the plane.
Line Plane	Mate (plane, line)
Point Plane	Mate (plane, point) Mate (plane, spherical face) Note: The central point of the sphere remains in the plane.
Spatial	No constraints
Welding	Combination of three constraints or two inserts
