Showing sketches as geometry

I'm not sure if I've worded the subject well or not...

I import silkscreen and drill pattern sketches for PCB designs into
SolidWorks to double check the design for mechanical fit and interface
components. I would like to be able to show this sketch as a
silkscreen on the surface of the PCB but have other geomety (such as
the components and enclousers) be able to obstruct viewing of the
sketch. (i.e. I don't want to see the sketch through the housing or
from the backside of the board.)

 

Sounds like you could use a sketch picture?

 

Sounds like a job for decals.. Photoworks>Decals You can also use
transparency channels to hide background colors and only show the
circuit paths on top of the geometry. Decals when applied to a face are
normaly covered up by subsequent geometry, as opposed to Sketh images
that are always visible. I believe that this is the only viable
solution.
