Here is an example of one piece of software that would be nice to have, but
it is not available for download....

http://gfx.cs.princeton.edu/pubs/Luo_2012_CPM/index.php

It would be cool if OpenSCAD could do that with any stl or other 3D file.

This is exactly what I wish I can do using OpenSCAD. I design a lot of
stuff myself that assembles like this, but have failed to do it to
anything non-trivial in OpenSCAD.

For me, this issue and the issues with colouring parts unless you
sprinkle render () throughout your code are the two biggest annoyances,
but they also seem to be the hardest to resolve.

You may get something similar with the PuzzleCutLib found in Thingiverse
https://www.thingiverse.com/thing:35834. A discussion on alternative

Hi Ronaldo:

Puzzlecut is what I am using. And your second link was a thread of mine. I
have an updated version of puzzlecut lib corrected for the current version
of OpenSCAD. That was problem one and it was solved. Problem two was my 3D
model which some one was kind enough to fix to work in OpenSCAD. But I can't
expect someone else to fix my models every time I want to use puzzlecut with
a thingiverse model or one from another source. OpenSCAD needs to be able to
deal this any manifold model, not just models created in OpenSCAD or that
have be corrected by an expert in 3D modeling.

Isn't that just a contradiction to what you say here:

Who's gonna take on that burden?

It's one thing to constantly need to fix a files to work with a piece of
software. It's a one time deal to correct a program so that fixing is not
needed any longer. Good software just works. At lease one hopes it works at
some point.

Well, at lease there should be some specification for the stl that will work
with OpenSCAD. There isn't one that I know of. And a utility to correct and
make any stl meet that spec so it will work in OpenSCAD without needing
expert knowledge of 3D modeling would be great. I only have two goals. One
is to take any stl and break it up using the puzzle lib. And second to
modify any stl, make bigger/small add/subtract features. That it. Perhaps
some one can suggest another free too that can do this?

It has to be 2-mainfold and have vertices no closer then the OpenSCAD snap
grid defined in grid.h that I linked to earlier, I think.

The bugs make it very difficult to work on STLs if they have a high
triangle count. CGAL also becomes impossibly slow.

Hi Nophead:

I just did a search of my OpenSCAD install driectory, and I don't find such
a file.
