Why do new floating parts appear after I select and delete visible ones and then zoom in on the model?

The floating part removal function currently operates on a “what you see is what you get” basis, which only eliminates the floating parts that are visible in the current view.

As you zoom in on the model, model blocks get updated, and previously unseen floating parts will then be displayed.

Recommended workflow: select all floating parts> deselect the ones to keep > delete, so as to keep the larger visible floating parts and remove the others.
