How can I use an AutoCAD file (*.wmf) as the graphical background?
In order to use an AutoCAD drawing as a background information source, proceed as follows:
Select the parts of the AutoCAD drawing you are interested in use the AutoCAD export function with the wmf option. Note, the exported wmf file will have the same layout as the window size you had during exporting. The colours will remain as they were in your AutoCAD drawing. If you need to change the colours you have to change them prior to exporting.
In order to learn how to use the background functionality refer to the User Manual, Chapter "Network Graphics", Subsection "Layers".
