Adds extra edges when preview smoothing?

[Anonymous]

Hello,

I ran into a bump while modeling a video game controller. When I go to preview smooth, Maya adds these weird edges that cannot be selected to the face of the model. Anyone know what this is all about?

Thanks in advanced!

you got some dirty modeling there, look in close up and double check your geo...maybe extra vertices floating around...keep all quads as much as possible.

there's a weird edge across too that is pintching right above

Thanks for the reply! Yeah, I extracted then combined and merged vertices...turns out there were some edges that didn't combine correctly.
