Scaling

[rpavlik]

Tables and chairs appear too short, and the big green drill press (or whatever) near the RP machine looks too large.

If models have accurate sizes in SketchUp, and are exported with the default scale to meters, then no scaling should be applied. (And, the default exporter also requires no rotation, at least for the default SketchUp coordinate system).
