Move Set of Points > Perpendicular (Modify Menu)

This command can be used to move a set of definition points. The movement takes place perpendicular to a specified reference object.

To make the definition points more recognizable, you should turn their display on. This can be done with the Miscellaneous > Display Point Markings or by pressing the '.' key (unless you changed the key assignment).

Choose the points that shall be moved. Click on points to choose them.

Definition points in Construction Aid endless lines and beams can only be chosen if both check boxes "Point markings" and "Also for Construction Aid" in the "Additional Information" area of the "Screen Settings" dialog are active. Otherwise, they will be ignored.

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

The identified object is referred to as the "reference object"

If an ellipse part is identified, then the position at which the (part) object was identified (the ID point) affects the rest of the command. If a perpendicular is dropped on to an ellipse, then it can end at either side of the ellipse. The point closer to the ID point is used as the end of the perpendicular (see graphic).

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

The target point can be positioned on the straight line between the end of the perpendicular and the reference point. This line, the "reference line", is displayed.

The possibilities which can result from moving individual definition points are varied. The consequences are equally various and can be unexpected. Many definition points have a close relationship to other definition points and can only be moved in certain ways. Under some circumstances, some definition points can not be moved because of object parameter settings. Be sparing in the use of moving individual definition points.

Moving multiple definition points parallel to a reference object is useful, for example, if a sloping opening drawn in the plan view is to be enlarged or reduced (see graphic).
