Bug in Union

[oschakravarthi]

Hi,
Overall it us a great implementation. Thanks you.
When I union a lot of CSGs, noticed that few CSGs are missing in the result.

What could be wrong?

stl_boolean doesn’t perform well when doing multiple operations. The rebuilding and simplifying of surfaces that OpenJSCAD does needs to be ported for it to work better.
