Removing and Adding Tangents

Effects > Garbage Masks > Manipulating Vertices and Tangents >

You can also use the Break option to remove tangents from vertices by clicking the vertex while in Break mode. When you remove a tangent, the curve defined by the tangent is removed.

The shape of the border line differs depending on whether adjacent vertices are broken:

If adjacent vertices are unbroken, the border line curves as it approaches the vertices.
If adjacent vertices are broken, the border line is straight as it approaches the vertices.

You can create a garbage mask composed entirely of straight edges by removing the tangents from all the vertices:

To remove the tangent of a vertex, select Break and click the vertex.
To add a tangent back to a vertex, select Auto and click the vertex. Alternatively, using the Break option, click the vertex and “drag” the tangent out again.
