Once youve put the files in your plugins folder, you just select the geometry you want to subd and smooth then go tools->catmull clark subdivision.

what i did is, 1 put the plugins in my plugins folder, 2 create a box, and pull it up into a 3d cube, 3 select all, then go to tools, and catmull clark, when i do this, these three little dots appear, very small dots, but nothing else happens?

yeah this happened to me but what i did was select the box and erase and found the subdivision was inside the box!! i guess the three dots were the points of the subdivision poking thru.
hope this helps.
