# ImposedMotion Command

This command is used to construct an ImposedMotionSP constraint which is used to enforce the response of a dof at a node in the model. The response enforced at the node at any give time is obtained from the GroundMotion object associated with the constraint.

```tcl imposedMotion $nodeTag $dirn $gMotionTag ```

nodeTag

tag of node on which constraint is to be placed

dirn

dof of enforced response. Valid range is from 1 through ndf at node.

gMotionTag

pre-defined GroundMotion object tag
