I'm having a problem that is universal to any shapefile that I'm trying to convert into a DXF with QGIS.
I've used the "Export DXF" option in the toolbar as well as the "Save As" option when right clicking the layer and neither will work. If I use the "Save As" the data will successfully export into a DXF file. The problem is when I try to open that DXF in AutoCAD. All of the information is there, but it's at a microscopic scale (1100 feet turned into something like .003). If I measure the same distance in the original shapefile in QGIS, it's spot on. I also just tried opening the DXF back into QGIS and that lines up perfectly as well.
I also tried scaling the drawing in CAD (not perfectly precise but just to get something workable) and it wouldn't scale correctly. If I choose two points and then specify a length it doesn't come anywhere near matching that length. It's almost like it's a difference between the "Length" measurement in the properties menu and the units being used to perform the actions (although I don't know of any units that scale to 1:5,000.
Does anyone know why this happens or how to work around it?
