Brian,
more on our (my) methodology. Typically we import DXF or Gerber from
our RF design/simulation tools. I prefer DXF because Gerber typically has
too many individual drawn elements making up everything. I then use the DXF
as a template and duplicate the circuit using traces where applicable and
fills where square ends are required or the copper element is square or
rectangular.
Using the DXF I can usually pop the curved line portions to the
conductor layer and don't have to enter the curves through Protel. Then I
can attach a regular trace to the end of curve for a perfect match. The DXF
rectangles and squares typically come in as fills (unless they are rotated)
and again I pop them onto my conductor layer. The fills which are rotated
come in as outlines or a polygon type outline and I will carefully replace
these with rotated fills on my conductor layer, using the original as my
guide.
