Hi Michael,

Here's a little example of vanishing style when using the fillet command.



I find the behaviour a little bit strange. When I add a fillet on the right little sphere, MoI seems to simplify (merge ?) surfaces from every existing other fillets, so I'm losing my style definition.

I don't often create styles that way (in the middle of a fillet surface), and there are workaround like separate the object based on style before adding new fillets. Still it's a little bit odd in that scenario.
