Hi Michael,

>>>It is, but this should only make a difference in a few particular instances, it isn't something that you should need to do on a regular basis or anything.

On such a simple boolean, I am more surprised than anything that it had not been reported during beta, had it?

>>>Please let me know if you run across this more frequently.

It would depend if I starting looking. Like on the simple example shown, I simply revolve the sphere. Various rotations will give various results. It is repeatable. But I mainly see such problems with 3d mesh.

>>>in this case the bug is not in my own code but in the geometry library that I'm using.

Does the library get updated with bug fixes?
