Tangent > Object - Point, Vertical (Draw Menu)

This command draws a vertical line which ends tangential to a circle, an ellipse, or a Bézier curve. "Vertical" takes the current view into account, so it is always vertical with respect to the screen!

Any circle, ellipse, or Bézier curve which exists independently or as part of another object can be identified as a reference object. This can also be the arc of an ellipse segment or a circle arc within a surface.

The position at which the object was identified (the "ID point") affects the rest of the command. If a vertical tangent is placed on a circle or an ellipse, this can occur at the left or the right. The line will end at the tangent point which is closer to the ID point (see graphic).

If a contour section consists of several Bézier curves, the ID point must be placed on the respective Bézier curve that contains the desired tangent point.

After identifying the object, a straight line appears which runs vertically and is tangent to the identified object.

The end point of the tangent can be entered by clicking the mouse anywhere in the drawing. A perpendicular is dropped from this position to the reference straight line to determine the tangent's end point.

The line is assigned to the current layer. In addition, it contains a reference to the current pen.
