Scaling problem

I have a large site model in 1:1. I worked in meters. now I need to scale it down in order to make it fit in a digital router. The first thing I did was to change from meters to mm in my preferences. Then I use Scale (3D).
The surface gets really destroyed, unusable. Any suggestions?

It’s impossible to guess without an example file and parameters you’re using that illustrates the problem.
