                 You can of course easily add others if necessary.
                 When Line is selected from the Draw menu on the first layer a thin chain line can be
                 drawn. Constructional details with thin continuous lines are drawn on the second layer.
                 Hidden detail is shown by thin dashed lines. The fourth layer is used for thick finished
                 outlines.

                 Colours can be selected for each different line style. As well as making it easier to
                 interpret the linework, it is also a pleasure to construct it in interesting colours.
