You can critique the design of your product on your computer using Autodesk's Design Review. With the Design Review you can rotate the 3D image of your product, zoom in, and tell us what you think about the design.
The Solid Model of your product is converted into the DWF format, and then uploaded to our server for your review. Once you've approved the design, we can start the prototyping process.
For the security of your product information, we provide a Non-Disclosure Agreement Form that allows you to easily generate a Non-Disclosure Agreement (NDA). An NDA is simply an agreement that restricts our use of your information. While we have no interest in profiting from your product information, an NDA is a written agreement that states that we will not disclose your information to anyone you do not want the information disclosed to. It also states that we will not profit from your information in any way.
Click here to generate an NDA. You'll need to sign it and send it back to us. The last paragraph on the NDA explains how.
