cut extrude sketch profile to a surface
the attachment is a solid body of half a fish. i would like to shell out the inside of the highlighted sketch which would make the body of the fish hollow with a wall thickness of 1mm and the tail solid.
my question is how do i do an extruded cut of the sketch to and make it finish inside the fish instead of cutting right through it?

have you looked at the shell command?

fish don't have shells, surely you need the scale command.
use the offset from surface
set the distance to 1mm
and check the translate surface option
this works for me

i used the translate surface with the offset from surface.
the shell command wasn't suitable as it would have shelled the whole body.
thanks manxjim for your help.
