With the GGUCAD program you can edit all drawings and diagrams created in GGU program systems. Additionally, it can be used as a full CAD program. Up to 5 drawing levels can be used simultaneously, independently of one another. The individual levels can be presented in different colours or blanked out, to provide a better overall view. A variety of actions and preferences for use with lines, e.g. trimming etc., can be used for drawing. You can use parallels, perpendiculars, circles, rectangles, bezier splines and automatic measuring. You can cover whole areas of your drawings with a variety of functions. It is possible to use colours, lines and colour fill for areas, as well as normal hatching.
