Focus Tangent

The Focus Tangent option allows you to generate slip circles which are TANGENT to a line segment. To create a Focus Tangent:

  1. Select Add Tangent Line from the Focus Search sub-menu in the Surfaces menu.

  2. You will be prompted to enter two points defining the tangent line. Enter the points graphically with the mouse, or enter x,y coordinates in the prompt line.

  3. After the second point is entered, the tangent line will be added to the model, and you will automatically exit from the Focus Tangent option.

An example of a Focus Tangent, and the resulting analysis, showing all generated slip circles, is illustrated in the figure below.
