how?

I do a high-res scan
and then import the bitmap into my cad program. (Rhino) Then I
simply trace lines arcs and splines over the scan. Seems to work much
faster and better that way.

I agree with John. Raster to vector converters suck. Most of the
drawings I work with fit in a normal scanner. I do a high-res scan
and then import the bitmap into my cad program. (Rhino) Then I
simply trace lines arcs and splines over the scan. Seems to work much
faster and better that way.
