A background drawing can be added by pasting it from the clipboard, for example from a PDF document, or as an image (png, jpg, tif, bmp). Then the shaft geometry can be drawn as a polygon. Scaling of the background graphic is also possible. Alternatively, the shaft geometry can consist of several shaft segments. The mouse (left mouse button + SHIFT key) can be used to adjust the lengths and diameters of the shaft segments to the required size.
