Hi,

I'm having some troubles with extrude-sop and negative inset value, because of intersecting polygons. Is there a way to to fix the problem or a better way to achieve a simular effect?

thanks

yep this is an old unresolved problem; do a search for inset…
in this case though you can probably get away with scaling instead.
also there's a LW plugin called bevel++ that seems to handle the problem, if you have LW.
