Ok i'm still somewhat new to maya, but i've been giving it all my time. I started on the Cartoon dog tutorial bout 3 days ago to see if i could do it but i ran into a few problems. Specificly when i tried to merge my converted polygon pieces, I would do exactly as it showed, but mine only disapeared. I seem to have tried everything in my power to remedy this problem but no hope is in site.

The error message I got after ctrl + z was: No vertices were merged. Tolerance too large - no geometry left after merge

eternaly greatful for any help
