---

This command is used to construct a single MP_Constraint object.

rigidLink $type $rNodeTag $cNodeTag

---

$type	string-based argument for rigid-link type:
	bar only the translational degree-of-freedom will be constrained to be exactly the same as those at the retained node
	beam both the translational and rotational degrees of freedom are constrained.
$rNodeTag	integer tag identifying the retained node
$cNodeTag	integer tag identifying the constrained node

NOTE: The constraint object constructed for the beam option assumes small rotations

EXAMPLE:

rigidLink beam 2 3; # connect node 3 to node 2 via a rigid link-beam.
