In working on some projects, I had a random question about scaling.

If for example I have a blueprint for something in 1/72 scale, and use that to create my 3D object, is it possible for me to just re-scale the entire object by 50% in all directions, thereby creating the same object in 1/144 scale?

Since I'm going to be using MoI for mostly modeling purposes, and a lot of drawings I have are in all different scales, it would be nice to be able to work with my drawings at their current scale.
