Construction Aid Line > Horizontal (Construct Menu)

This command draws a horizontal Construction Aid line. "Horizontal" takes the current view into account, so it is always horizontal with respect to the screen!

The position of the horizontal Construction Aid line is determined by a reference point through which the reference straight line should run. This reference point can be entered by clicking the mouse at any point within the drawing.

After entering the reference point, a straight line running horizontally through the start point appears. This is referred to as the "Reference straight line".

The start point of the Construction Aid 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 Construction Aid line.

The end point of the Construction Aid 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 Construction Aid line.
