@ BB hope you write that book before I'm too old to understand it ;-)

 

@MLP Dr Geep has a ruler (caliper) in one of his tuts , make some scaled cubes in poser ~ export as obj, then import to wings as size guides when you have a couple (eg 1 inch an 1 foot) then set your guides in wings (sure you have them but I dont use wings now)

have to say its a lot easier to use metric ;-) point 1 of a foot is hard math :-(
