[OpenSCAD] Export Wireframe

This might be a silly question but is there a way to export the wireframe as
an STL file?

An STL file only contains triangles so I don't see how that would be
possible unless you mean the wires should be rendered as cylinders.

Basically what I am wanting do is the when using the wireframe mode in
OpenSCAD I was wanting that as a STL file but sounds like that is not
possible. Guess I will have to come up with something else.

You can pull the normal STL file into other programs and tell them to
render it in wireframe mode. I.e. wireframe is a an alternative way of
rendering a mesh. It isn't a file format as the information is exactly the
same, you just draw the edges of the triangles.

That's okay, will come up with something else. I was hoping openscad could
do it since it has the option to batch mode from command line, I have like
1,000 or so files I was looking at doing this with. No worries, did not
think I would be able to but I figured it was worth asking but also a long
shot.

Thanks, I have not really used Blender much, maybe I will give it a try and
see what I can come up with.

I personally would go with blenders wireframe modifier.
Blender can read STL Files. Blender can be scripted.
I mean, the result will be similar to what fred_dot_u has described
using meshmixer.
It will depend on what software you prefer.

If you just want png renders with wireframe switched on from the command
line then I think that has just been added to the latest snapshot, or will
be soon. All the view options have been added.

I think the likelihood of this not being a suitable answer is high, but it
might provide some useful information anyway:

Meshmixer is free and Angus (Maker's Muse) is pretty good at explaining
stuff. He converts the Stanford Bunny into a low-poly model, then converts
the edges to rods/tubes. The result is a wireframe looking model that can be
exported as an STL file.

An STL file is just a "triangle soup", with no connection between the
triangles. If you draw every triangle as a wireframe, then each edge
will be drawn twice (i.e. "2-manifold").

If you export as OFF, then the triangles are connected and it is
possible to identify each edge and get a proper wireframe
representation.
