Add polyline objects

Add polyline -> select layer

A polyline must be drawn. When drawing this polyline use the right mouse button menu to change the drawing direction, goto the previous polyline point (Backwards) and to finish the polyline drawing. When the spacebar is pressed, a dialogbox will popup, and the polyline parameters can be edited by hand. As many as 200 points can be edited. The coordinates typed in will be used with the current units (dimension).
