The latest Version (188.8.131.52) of OSM IQ supports the export of OSM data to Dxf. Since CAD systems have typically limited capabilities to transform data, you can choose the target coordinate reference system (CRS) during the export.
Converting OSM to Dxf can be done in a few steps:
- Navigate to the area of interest and download the OSM raw data
- Choose a tag or a tag / value combination that you are interested in
- Click Export and you will get a list of suitable CRSs (a pre-filtering is done based on the extend of the OSM data)
- Use the OSM data in the CAD system of your choice
