GGU-DIRECTSHEAR: "Pen colour and width" menu item
For reasons of clarity, different colours are used as default for graphic presentation of the different lines, as well as the type of dashing. With this menu item you can alter the preferences to suit your wishes.

The pen width, line type and dashing can be edited for the listed lines and, after clicking the appropriate buttons, the pen colours be adapted.
On monochrome printers (e.g. laser printers), colours are shown in a corresponding grey scale. Graphic elements employing very light colours may be difficult to see. In such cases it makes sense to edit the colour preferences.
