# Tangent Constraint

Makes an arc or circle tangent to another arc or circle, or to a line.

- Start with a line and an arc/circle. Activate the
**Tangent**constraint and select either object (when one object is a line, the selection order does not matter).

- Select the other object.

The line is moved, in an offset direction, so that it is tangent to the arc/circle. The tangent constraint symbol is added at the point of tangency.

- If you edit either object, the tangent constraint will be maintained.

If you apply this constraint to a line whose offset will not meet the arc/circle . . .

. . . the line is moved so that its extension is tangent to the circle.

You can also make two arcs/circles tangent to one another. In this case, the first selected object will move to meet the second selected object. If the arc does not meet the other arc/circle . .

. . . the arc is moved so that its extension is tangent to the arc/circle.
