Subdiv works on polygons that have a maximum of 4 vertices, but if I have a (fairly) complex model in which some of the faces/polygons have more than 4, I can manually go through and trim them all till subdiv is happy (which can take ages) but is there a script or command - or even a standalone app - which will find those polygons and do the job in 1/1000th of the time?

I know it's been talked about a lot but I thought I'd ask here first rather than scroll through the forum history ;)

Cheers in advance
