Hi! I made a model using Inventor, with the dimensions I wanted it to be. In the archive containing the model I specified "inch" for the units, and converted it to stl format in order to it could be accepted and uploaded with any problems. Then I uploaded the model to shapeways and I had to choose the units of the model, so I indicated "inch", the units I had been working with. My problem is that once the model has been correctly uploaded to "my models" the dimensions that are indicated there are not the same that the model really has, they are completly different. This is the first time I upload a model to Shapeways, so I would thank you a lot to help me, because I don't know if I'm doing something wrong.
