Hi Walt,
I would load the dxf file with the modified building in QCAD and
move/translate the data there. After saving the modified dxf file, this
should import in QGIS at the correct location.
You will need two reference points from the existing building structure
- you could for example export the existing data set from QGIS to dxf
and load it in QCAD as a reference or write the coordinates of two
points out manually in QGIS.
Regards
Jochen

I've received a 3D AutoCAD file from an architect that i managed to
convert into 2D .dxf format and import into my QGIS project, but it is
out-of-scale and out-of-place, so i guess i need to add some
georeferencing coordinates to the file.
This should be easy enough, since it's an accurate representation of a
building that's already in the project -with an additional wing tacked
on- so i'm thinking i could just use a few corners of that existing
buildings as ground control points, and map them to the corresponding
corners on this .dxf model, then maybe all other co-ordinates could be
automatically generated by some tool, if i could just find the right
one for the job.
Is there in fact any such easy way to do this thing?
