Quick Reference

A tangent constraint forces two curves to maintain a point of tangency to each other or their extensions.

Apply a Tangent Constraint

In the example below, a tangent constraint has been applied to the circle and line on the left. The result is the block definition on the right, where the constrained line is tangent to the circle.

Manipulate a Tangent Constraint

When you manipulate a block with a tangent constraint applied, the object selected second will always remain tangent to the object selected first.

In the example below, a tangent constraint has been applied to the two circles on the left. The size and rotation of the circles on the right have been changed, but the tangency remains.
