Constrain a circle, arc, or line to be tangent to another circle or arc. If one object is moved, the other constrained object adjusts to maintain the tangency. The objects do not need to be tangent to one another when you place the constraint; the first object moves to become tangent to the second.
To constrain a circle, arc or line to be tangent to a circle or arc:
Click the Constrain Tangent tool from the Dims/Notes tool set.
Multiple dimensional constraint tools share the same position on the tool set. Click and hold the mouse on the visible tool to open the Pop-out Tools list and select the desired tool.
Click the circle or arc to constrain.
The cursor switches to the bull’s-eye cursor.
Click the circle, arc, or line to be constrained.
A green tangent constraint is drawn at the tangent point of the two objects.
