I have this problem with my rotate tool...when i try to center pivot it gives me an error:
Warning: Cannot use 'xform' command flag '-centerPivots' to modify components
I'm attempting to center on vertices selected so that i can rotate them correctly...unfortunately my pivot always stays in the last place it was at so i'm constantly having to move the pivot manually and it really slows me down...plus it's more than slightly annoying

anyone know how to fix this?
