Bug: Phantom Body in Browser after Complete Cut

[mavigogun]

Attempting to define the confines of Boolean capacity, I began by Revolve cutting a sphere from another identical sphere.    Despite apparent complete removal of both Bodies, a Body is still listed in the Browser.   Suspecting the presence of micro artifacts, I created an enclosing Body and performed an Interference Inspection, with no Interference reported.    The Body has no volume.

Design attached.

Interesting test!

I also believe that there is a micro artifact left that is not visible.

CAD software internally works with tolerances and these tolerances might be different for different tools.

The interference tool might for example have a higher tolerance to avoid false positives.

The boolean combination might have a much lower tolerance so there is a mice artifact left that is just a hair larger than that tolerance.

Then the viewport (LOD) code has a very large tolerance  and that micro-artifact is simply not rendered.

Of course this is all wild speculation 😉

Examining the Body's Properties indicates no mass or surface area.

On the topic of just how closely co-located surfaces can be for Combine/Cut/Join operations, I posted the findings of a study- find it here:

Bump.
