What ever happened to logic? Imagine how useful it would be to have a logical and rational progression of scales to allow for reasonalbew choices for layouts in existing spaces. Wouldn't it be nice to have the choice of 1:24, 1:36, 1:48, 1:60, 1:72, 1:144 and so forth. That's what happens when you let toymakers start something. BTW - what the devil is HOe scale?
