I have a .dwg/.dxf file that needs to be georeferenced so I can draw some boundaries on a site in Indianapolis, Indiana, USA. I'm using GQIS 3.18.2, only the .dxf file will be imported. Now when imported, the data shows up as the map figure as a whole (reading the legend etc. as data). This is floating in space. Under layer properties, I can view the extent as (-362.3947145426504903,-998.1682020468679184 : 2891.9386173585958204,1472.8011332957680679). I've tried playing around with the "brute force" method but cannot seem to land on the right one.

full extent showing data in center of map, where its supposed to be in Indiana, USA .dxf file imported to QGIS, after setting CRS at WGS 84/Pseudo Mercator (EPSG: 3857) for all layers and map.

The CAD drawing seems to use a local coordiante system with meters or feet as units. Furthermore, the map is rotated, because 56th East Street stretches East-West and Drum street North-South.

Best choice would be to ask the author of the drawing what coordinate origin they have used, and what units of measurement.

A brute force method would be to georeference the creek against aerial photos, but I assume the creek is not drawn exactly enough for that.
