Line > Perpendicular Append (Temporary Objects Menu)

This command is used to create a Temporary Object as a line which runs perpendicular to a line, circle arc, ellipse arc, or Bézier curve.

After identification, a straight line appears which runs perpendicular to the reference object. This line is referred to as the "Reference Straight Line".

The end point of the line 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 end point of the new line.
