I have a similar problem with stellation mode, where trying to select one cell selects something far away. Sometimes, zooming in prevents this problem from happening, but it's an inconsistent fix.

Is it possible to include a feature that restricts stellation planes to the area inside existing faces? For example, this feature could stop a small stellated dodecahedron from stellating into a great dodecahedron.
This could make net generation easier for extremely complex models.

The one specific case I remember is Sidphippixhi down a dodecahedral axis at a depth of ~0.127322. I've seen this elsewhere, but don't remember which polychora do this.
The slice does seem to be itself degenerate.

Sometimes, slicing a polychoron to certain depths (usually where vertices are found) and setting that section to the base model will result in it having "no symmetry", regardless of the symmetry of the axis sliced through. Is this something that can be fixed?
