list index out of range while generating bom

[JamesGlanville]

The stls build fine, but I get this error when the bom gets generated. This is using today's git (3554174) but I've had it before, and have never successfully built a bom. This is an untouched repo, no changes to configuration files.

./make_machine.py mendel
Generating bom ...

look at openscad.log file in current directory.Does it looks like this?

I pushed a fix but I think that bug only occurs if there is a part outside of any assembly. Since everything should be inside the machine assembly that should not happen, and indeed it does not on my PC.

Please try the fix and compare the generated BOM with the one on GitHub.

Try to run it with this patch and look at last line before traceback

I think the problem might be in my openscad version, sorry for saying the stls built ok, I don't think /all/ of them did, the last bit of openscad.log is:

CGAL Cache insert: multmatrix([[0.913545,2.49046e-17,-0.406 (124 verts)

I'm trying the latest git and sevikkk's patch, this slow netbook will take a while to check, and meanwhile I'll get the latest openscad
