This command is equivalent to the Tangent option in GEOMCONSTRAINT.

Following are the valid constraint objects and points:

• Line
• Polyline segment
• Circle, arc, polyline arc, ellipse
• Combination of circles, arcs, or ellipses

A circle can be tangent to a line even if the circle does not touch the line. A curve
can be tangent to another even if they do not physically share a point.
