I am not a frequent Autocad user.
I wanted to export some floorplans from Autocad 2016 DWG to a final GeoJSON file to be loaded in a Google maps JS app.
My steps are:
1)in Autocad set a location of one of the drawing points with Edit location-> From map, choosing an arbitrary SRS (Mercator, pseudo mercator, local)
2)save as DXF
3)open in QGIS setting the origin SRS, or convert with ogr2ogr setting source and dest SRS or load in https://mygeodata.cloud converter
4)view the shape: the shape is correct in both proportions and shape, but it always gets placed between Latin America and Africa ((0,0)???)
I don't know actually if i'm doing something wrong in Autocad or elsewhere but i have no more ideas left.
