A long discussed issue.

I always propose the following simple trick - that btw should work in Bryce too.

Define a cube in your modelling program that surrounds your whole "world". Then, with every item you export export this cube with it. And import this combi then into Vue (or Bryce). Whatever the scaling might be, it will then always be related to the same item - the surrounding cube. After that delete this cube simply and all should be where it is supposed to be.

But on the other hand, Vue has in its preferences an option saying that you can switch the auto resize and center off - should work as well.

The problem you might stay with is the size of your Vue native content - vegetation etc. This you have to do manually. Vue is an illustration program, not an architectual simulation one.
