I dunno where you could find all the commands for 3D.
here's the biggies off the top of my head
SOLIDEDIT
SLICE
EXTRUDE
REVOLVE
LOFT
SWEEP
REGION
INTERSECT
SUBTRACT
UNION
ALIGN (using this in 3D is much dif than in 2D so it warrants repeating)
.x
.y
.z
(yea, point filters aren't 3D exclusively, but they're uber important in 3D, imo)
that's about all I can think of off the top of my head.
