I pulled the file up in blender. Each dimension in sketchups Dae according to blender was mm.354 x 3 x3. . So the DAE possibly might have scaled a Sketch up unit to a mm. I am guessing SU's basic unit of measurement might be a mm. Try it with a stl model imported to nettfab. Check the dimensions. Net fabbs dimensions usually agrees with SWs.
So if you want your basic unit in Sketchup to be regarded as an inch, when you browse your file to upload to SW, change the bottom selection to inch. It would not have mattered anyway, the model needed doubles removed, some face normals flipped, and two verts merged. Easy to fix
As for a test. create a 1 x 1 x1 cube in sketch up, export as a STL, then check dimensions in Netfabb. Or just PM me the file, lol.
