Hello Alex,
This sounds promising, but then so did the other plug-ins.
Where do I find the OGR2OGR functionality? I found some
help information referring to it but nothing about how it is accessed.
Not sure why I would need to create the control points from
the raster georeferencing as I already have them from fieldwork or
other sources. What I do need is a function or tool to rubber sheet
the un-projected coordinate list onto a projected layer containing
the control points.
My CAD program is not able to do this. I tried manually
shifting and rotating but that is a very sketchy process at best. My
testing so far indicates that the transformation to UTM will require
both scaling and rotating.
Thank you, Cheers . . . . . . . . Spring Harrison

My trick, is convert the vector an image in QGIS (Save Image)
Georeference the image, saving the control point list out to a file.
You can then use these control points (gcps) with ogr2ogr to transform
the original vector.
