Creating a Bi-Tangent Line

This task shows how to create a bi-tangent line by creating two tangents (on two different elements).
Create two circles.

  1. Click Bi-Tangent Line from the Profiles toolbar (Line subtoolbar).

  1. Click a first element (first tangent). For example, click a circle.

  1. Click a second element (second tangent). For example, click another circle.

The bi-tangent line appears between both selected elements.

The bi-tangent line appears as well as the corresponding constraints provided you activated Geometrical Constraints .
Tangents are created as close as possible to where you clicked on the circle.
At this step, create a  point.
At any time, you can select a point type element. The line will go through this point and a coincidence constraint is created on this point.
