I've got a question about general scaling of a given model. If I have an 6" figure, (along the lines of a Star Wars Action figure or so) at what scale would I have to build, to have the figure match the model? I've been fiddling with the math for a while, and I just cant get it to come out to a reasonable scale. Anyone?

You would have to assume that the 6" action figure is a rough real world scale height of 6'-0". The GI Joe figures of the 60's were 12" tall and are 1:6. So 1" = 1'-0" or 1:12.
