You need to reimport the DWG. Hopefully you used XREF Management - simply detach the current DWG and attach it again with the correct drawing units (1 foot). Otherwise you will have to do it manually, by deleting the DWG and bringing back in. Either way I would back up first and use XREF Management to bring it back in, if practical..
Link is right about bringing in DWGs from people who use decimal feet by changing the drawing units to 12 inches. And you should always check that the drawing came in at the right scale before you do any work on it. I have a feeling that you did not use XREF management to bring it in and have moved things around.
If I'm not using XREF Management, I never really worry about what scale a DXF or DWG comes in at anymore, even though I try to set the drawing units properly. You can waste lots of time trying to figure out what scale something came in at with many possible scenarios.
As long as there is one known dimension in the drawing you can:
1. Make sure all of the DWGs layers are visible (nothing else)
2. Activate the Arrow tool and Select All
3. Chose Edit/Resize
4. In the Resize Dialog box check Define graphically as well as the remaining 4 Options.
5. Click at one end of the object of known length (I believe you mentioned a 48' object showing up as 4") (it could be a dimension string)
6. Click at the other end of the object of known length(in your case the "R" value in the coordinate box should read 4')
7. Without moving the mouse, type R, type 48 (length of object), hit the Enter key (Return on a Mac)
The entire DWG is now properly scaled and the work you have already done not lost (changing layers)
I even use this trick if I bring in an image (gif, tiff, jpeg) of a plan I would like to trace over.
