Move / Copy Objects > Perpendicular (Modify Menu)

This command can be used to move or copy all kinds of objects in the drawing. The movement can only be perpendicular to a reference object.

The objects to be moved or copied must be chosen first. Click on objects to choose them.

Any part of an existing object can be identified as a reference object. This can be a side of a rectangle, the arc of an ellipse segment or an arc within a surface.

The identified object is referred to as the "Reference Object".

If an ellipse part is identified then the point at which the object was identified (the "ID Point") is important. If a perpendicular is dropped onto an ellipse, it can end on either side of the ellipse. The point nearer to the ID Point is used as the perpendicular’s end point (see graphic).

The reference point for the movement can be entered by clicking the mouse anywhere in the drawing. A perpendicular is dropped from this point to the reference object.

The target point can then be placed on the line between the reference point and the foot of the perpendicular. This line, the "Reference line" is displayed.

The target point for the movement can be entered by clicking the mouse anywhere in the drawing. A perpendicular is dropped from here to the reference line to work out the target point for the movement.
