I want to import DXF/DWG files in QGIS, therefore I use the import function. The problem is, that I have to know the crs of the CAD file. Is there any way to get the crs in QGIS, because I have no access to a CAD programm.
If QGIS does not read it than you'll have to play the CRS dwg guessing game:
- Add control layer in Q that you know the CRS
- Add in the dwg or dxf file
- In Q change the project>properties>CRS to any possible CRS the dwg might be in (this is assuming you have knowledge of the geography of the dwg/dxf file). If the data aligns with the control layer then you've finished the game and figured out the CRS it was in!
