	Through Edge		Through Edge
	Through Cyl/Con/Rev		Through Cyl/Con/Rev
	Through Point		Parallel to Plane
	Angle to Plane		Tangent to Face

 

Angle to Plane	Through Datum Axis		Tangent to Face	Through Point
	Through Edge		Angle to Plane, 05 or 905
	Through Cyl/Con/Rev		Tangent to Face
Angle is 05	Through Point
Angle is 05 or 905	Tangent to Face	Offset from Plane	Offset from Plane

 

Offset From Plane (only one geometric constraint)

Through Three Points (three constraints)

NOTE: A "Through Point" constraint can only be specified by putting an edge in the object_tags array and an appropriate mid/end modifier in the point_select array.
