You need to get a 3d program, and learn how to pull the points to make a morph. I could not learn magnets to save my life. There are some links to free or fully functioning demo versions of a number of 3d programs. I use rhino, but, am on a pc....with rhino you can just draw a line, select your points and move them to follow that curve. i started doing morphs with anim8or....a free program, but, as i said, i am on a p.c. go to the modelling forum and check out the links to programs in the banner....i am sure one at least will be good for a mac.....then, go to www.anim8.com and check out the morph tutorial, there....really simple and straight forward regardless of what you are using.
