Yeh Chirone,

I was using 'alt ~' but now it locks it into sub-d (duplicates mesh), then I have to go to outliner to delete it.

bigtom did you extrude your wrist from the halfpipe hand?? I did mine the other way around? I created the arm, extruded the wrist space up into the arm, then duplicated that inside face, extruded back out and then booleaned the half pipe to the wrist. I would be interested in comparing notes.

cheers bullet
