Accurate Scaling with CADspan

Hi there,

I've successfully done a 3D print using CADspan with Sketchup, but had to manually set the size of the model on the printer. I really need the STL file when sent to the printer to be an exact size.

Most of my models are small, so I set the drawing scale to millimetres, and need the print to be exact.

Am I missing a step somewhere?

Any help much appreciated.

thanks
