I'm using 3DS max to design my piece. When I export to a .DAE file I get a warning about "Turned Edges". I have no idea what this means and have never seen it before. When I try to upload the file I get this message from Shapeways "Unfortunately, we were not able to process and thus print your product. The error message was: Your object has not the correct size. The size is 3.81 x 0.00 x 0.00 cm / 1.50 x 0.00 x 0.00 inch. We can only produce designs from 0.25 x 0.25 x 0.25 cm / 0.098 x 0.098 x 0.098 inch up to 70.00 x 38.00 x 58.00 cm / 27.56 x 14.96 x 22.83 inch (h x w x d). Please rescale it. " My model has correct dimensions in 3ds max of 3.81 x 3.81 x .35 cm and I have reset x-form and ran the STL check and everything seems good. Normals are correct and I'm trying to print it solid. Does anyone have any suggestions?
