This is probably a silly question but I am going to ask anyway.

I have created a library that allows me to basically generate 3D cubes with
some holes through the cubes and I can pass various parameters for width,
length and thickness of the cube. I was looking at having some pieces laser
cut out of metal but the company requires flat 2D SVG files. Without
rewriting my library is there any way to generate a SVG from what I have?

I'm not so sure about the not-rewriting part, as some code is necessary to
accomplish your objective.

The projection() feature will allow you to create an outline as if one had a
parallel light beam directly over the model and traced the shadow. One can
translate, rotate, scale as desired to develop the necessary section of the
model to outline.

The summary is located in the wiki manual
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/3D_to_2D_Projection
and is quite easy to understand.

Experiment with various locations/rotations and cut=true or cut=false.

The export menu entry supports SVG files. I was able to create a couple test
files and open them in Inkscape.

You can use projection() to convert a 3D object to 2D and then export an
SVG.

That is exactly what I need!!!!! And only adding 1 line of code!!!!!
OpenSCAD never ceases to amaze me with what you can do with it.
