hi michael,

thanks for the clarification. i believe i understand some more about the trailing edge being a tolerancing issue.

as far as the sweep i may have confused you. the blade is made by a sweep. then i cut away the hub portion using a Boolean op. the circular part of the blade is also made the same way. the transition is the part that i need moi for. in the old days we used to just put a note on the drawing that said blend. it was left to the guys grinding the blades out or making the dies to figure the blend out (depending on construction methods). so only that one piece is where there is a loft/blend/network type op. everything else is made with sweep.
