This utility allows you to draw a line or polyline starting in a perpendicular direction relative to an existing curved object. To use this utility, load the LISP code and type Perpl at the AutoCAD Command prompt. Next you will be asked to select a point on an existing entity object. The default operation is to start the Line command; however, you can type Polyline to have the program switch to polyline mode. The line or polyline will be started at the point selected with the direction vector set to move away from the object. All you need to supply is the distance for the first segment. The Line or Pline command then continues as it normally would.
