    Guys, I'm new to 3d design. I've been using sketchup to draw some parts. I uploaded the first one to Shapeways as a VMRL and got the manifold error message.

    I can't find any way of finding or eliminating the manifold errors in Sketchup.

    Can any of you guys help me out?

    I've attached the orignal sketchup file and the WRL.

    Hi Virtual V,

    Thanks so much :)

    I am having problems with the dimensions when uploading to shapeways. The original model was drawn using centimetres in Sketchup.

    If I upload using the millimetres or metres default, it comes out as too small or too large - the numbers are correct but the units don't translate over correctly.

    How should I correct this?

    Following up on this: It would be great -- and probably not difficult -- for SW to support "centimeters" as a scale option on uploading STL files. At least in Blender, the natural coordinates for modeling (using the default grid size, default view, typical scale of a SW object given current pricing, etc.) seem to match 1 unit = 1 cm most closely. Allowing cm as a scale option might lower an unnecessary barrier.
