I appreciate all the ideas. This site is awesome.

"The DeltaCAD can work with DXF files"

We like it because the engineer, or designers can send us the file on DXF, no problems so far, we had auto cad and it was bulky, and some of the files would corrupt, depending the version, for the $45 it was well worth it.
