Hi

I want to use Sketchup to print out cutting lines of an object (for woodcutting).
The files are already made and imported from .stl format, this works great except for the size.
For example if a cube was 4mm wide it will be 400mm wide in sketchup after imported.

Is it possible to scale the object down to get the correct format or change it to micrometer?
400mm that would work if I could change it to micrometer instead of mm, then that would be the same as 4mm right?
