Your guitar - small that I can make.
Simply, I can't brag: God doesn't resolve!
My task - to help all!

My design electro-acoustic bass based on a contra-bass.
I hand-coded the sound-box as a bezier patch. I CSG'd the C-holes out of
the soundbox but I couldn't add depth because I couldn't csg the sides o
f
the C-holes. I was thinking maybe this patch would make it possible.

Could you not subtract the a scaled down version to create the resonance
chamber?
I am assuming that the thickness of the upper and lower surfaces need
not be detailed modelled to get a realistic sound body.

It just ends up looking like a shadow. I need to do the walls/edges of the
c-holes and they need to match.

Right now, the C-holes look like they are painted on...
How about replacing the patch with an hight_field?
Do a render of only the front face using an orthographic camera and a
black to white gradient. Use +fng16 on the command line when using
version 3.7.
Add some slight bluring to get some beveling/rounding. May be done using
some focal blur or by post processing.
Use water_level to remove the outside part.
As it may be to thick around the openings, you can now use a difference
around the C-holes to get just the correct thickness.
For the back face, you can still use the bezier patch, or you can use
another hight_field made without the openings.

What about putting a thin box inside the soundbox behind where the C-holes are
then simply cutting a hole in this box as well?
