Have you tried daisy-chaining together something like:
- povray in two bit or grayscale mode, piped to...
- autotrace or another raster to vector converter
Obviously not an industrial strength system, but it would get the idea
across to peeps. The result would be imprecise in size/position but the
quality of the hidden line removal should be good.

having used rendering software to create a photorealistic scene from a
3D rib=20
file. i want to use the same concepts create a utility that would
"render" a=20
view from the 3D scene is to a 2D drawing based on the location,
direction,=20
and attributes of a plan(camera). =20
unlike most of you, i have not gotten far enough along to have any proof
of=20
concept. infact i'm still working on how to build a crude modeler to=20
impliment this. the examples in the book make it look easy, then just
try=20
doing something with it. :-\
in the basic case it would be simple. the basic views(plan, top,
bottom,=20
left and right) would be created by taking one of the major axis and
reducing=20
it to zero. then converting it to something like dxf. where multipule
views=20
can be detailed and demensioned. as time goes on more advanced features
would need to be added. the ability to render isometric views, auxilery
views, section views, section cuts, and filtering
the advange is that it would not matter who's modeler or who's drafting=20
package we use. as long as they work within the unix philosiphy. =20
"each tool does one thing" and they all work together.
i could use a opencascade based modeler built with TK/TCL to model my 3D
and=20
pythoncad or qcad to detail it. those that want their 3D managed by a=20
database could do that then export the scenes for detailing.
i'm rather determined that dxf would be a roseta stone. even though we
may=20
all want a common open format, we still have a real world we have to
live=20
within. just about everyone from catia to unigraphics can read a dxf.

Oh i've slipped the surly bonds of DOS=20
