Tangent Constraint
Use the Tangent Constraint to constrain two edges to have a point of tangency. For each edge, you can optionally specify an adjacent vertex as the point of tangency.
Add a Tangent Constraint as follows:
1
Click the Tangent Constraint () toolbar button.
2
Select two edges (and optionally a vertex adjacent to each edge), or a vertex having exactly two adjacent edges.
3
Click somewhere on the canvas to place the tangent symbol.
The Settings window for Tangent Constraint contains the following sections:
•
First Edge: Change the selected edge. To set the point of tangency to a vertex, from the Point of tangency list, choose Vertex, then activate the Vertex selection, and select a vertex adjacent to the edge. With the default setting for Point of tangency, Anywhere, the tangency can be applied anywhere on the edge.
•
Second Edge: Change the selected edge and point of tangency similarly as in the First Edge section.
•
Help Points: Change the help point coordinates for the selected edges. The help points are used as the initial guess when computing the intersection of the edges if a vertex has not been selected (see Help Points).
