I uploaded two sketches from AutoDesk Inventor 2013 that are designed in millimeters. I exported the files to STL format, and uploaded them to Shapeways selecting millimeters as my scale. My objects (both circular), which have a 50mm diameter show up as being a 0.5cm objects. This *should* be 5cm. The length, width, and height for both objects is off by a factor of 10 for both files. Is this a website bug, or is my sketch really going to come out a factor of 10 times smaller than it should when I print it?
