The problem I have is that my eyesight is failing. The only way I can see whether a plan is worth printing is to download it, this must increase your bandwidth use.
As far as I can see, (Not a pun ) Some models are what seems to be called "vector", they are very pleasant to resize, but the only way I can find out is to download it !
I would love to see some idea of the possibility of enlarging the model to my capabilities and it would reduce your bandwidth use.
