Tangent Arc Point

Creates a line tangent to an arc, circle, or ellipse, with the midpoint of the line located at the point of tangency.

1. Select the tangent arc, circle, or ellipse.
   
2. Move the mouse to adjust the length of the line, or set the length in the Inspector Bar. The line midpoint always remains at the tangent point.
   
3. Move the mouse to change the angle of the line and the point of tangency, or set the angle in the Inspector Bar.
