what you want blue prints or something ???
you will never find a top,side and front shot of a transformer unless you make them yourself.

dude I did find this for you though - but it seems to be the transformers after the movie only though

if you want photos of a transformer just image search the one you`re wanting to make - as there are plenty of toy sites with pics on them
