Silkscreen Overlays - DXF and multiple entities

Hello,

Presently,

1. I have a external program.
2. It calls SW application to open.
3. It creates a flat panel in SW based on the external program.
4. It then creates the silkscreen image by importing the x,y
co-ordinates onto the panel's face.
5. Watch 1000's of line entities being created in a SW sketch.
6. Extruded image is HUGE!

What I would like to do

A) I would like the silksscreened image to be represented by a series
of P-lines (Whoa! Haven't had to use that terms since '97). Can I use
the DWG EDITOR built-into SW to
a) create the series of lines and arcs.
b) Simplify the line representation by turning them into P-lines.
c) Importing the simplified representation into a SW sketch.
d) Extrud.

B) Is the SW API available to perform this sequence of steps?

Note - I've followed the thread with respect to SW2006 decals - this
wouldn't work for this specific case.
