"Snap-To" For Mac Finder?

I recall on WinDoze PCs, when you accessed a layout of several file folders or files, there was a "Snap-To" function you could click on that would perfectly arrange the icons or folders on a grid. When I go to Finder and click on a folder or group of files, they're laid out but not lined up perfectly like Snap-To would put them. I'm running Snow Leopard on a MacBookPro. Is there a like function on the Mac that will do that? Thanks very much in advance for your help. And yes, I'm one of those anal types that loves things perfectly lined up. I can't help it.
