I have a dwg in CAD, it doesn't have a projection, I need to convert this to a shapefile, how can I add the British National Grid and move the drawing to the correct co-ordinates?

Hi @saqibamin
Does your DWG file currently have a known coordinate system? If so, you can use the CoordinateSystemSetter. If not, you will need to move this file into a known location through the LocalCoordinateSystemSetter before reprojecting to the British National Grid.
If you do not have known points in the file linking 0,0 on the file to a known point on the Earth's surface, you may need to do some guesswork with Google Maps. Or you could try ArcGIS where I believe there's a tool you can adjust your dwg to the correct location against a basemap.
