[Qgis-us-user] Shape File in Wrong Location

Hey Tom,
What version of QGIS and on what OS?

Several things to look at:
1) The CRS of the source file
2) The CRS and on-the-fly projection settings of the QGIS project itself 
3) The CRS of the output shapefiles

The trouble sometimes with CAD files is that they can be created in unprojected space. I have run into this on multiple occasions, especially with older drawings. Does the AutoCAD file (DWG or DXF?) render where it should when viewed with OSM layers? Does the AutoCAD file have a projection system defined?

Another thing you can look at is the .prj file associated with your output shapefiles. You can open this in any text editor. It will have the projection definition for that layer. 

Let us know...

Best Regards,
James

They had an engineer provide an AutoCAD drawing several years back that have a lot of the system intact, but along with a lot of other info I don’t need. I imported the whole thing into QGIS and exported various layers I need as shapefiles. I then added the shapefiles to a QGIS project that includes an OpenStreetMap layer. Nothing showed when zoomed in to the community, so I “zoomed” out and out and finally found found the shapefiles rendered completely outside the OpenStreetMap layer (i.e. its a little rectangle) and to the right (east) also about 4-5 times the size of the entire OpenStreetMap layer showing the whole world.
