Thomas, Is there a way to do this other way around? i.e. if I have mesh information how do I convert it to Solid. I think that's what Chris was asking too. I've tried to do it (here <https://gist.github.com/1351019>), but the solids I create do not behave correctly in subsequent boolean operations on them.
Any hint will be appreciated.
