I would like to import CAD-drawings into TikZ to add some annotations/arrows/... . My CAD-software is able to export drawings as DWG/DXF and PDF.
I could of course import the drawing as a picture and overwrite with TikZ, but what I want to achieve is to control line styles of the drawing inside the TikZ code to have a maximum of consistency in the document, even when i change the picture size!
What I already tried was to import the PDF into Inkscape and ungroup it into its seperate lines. But unfortunately I cannot find the TikZ-export feature everybody is talking about.
Do you have any ideas, how I could do it?
