The CAD Models app provides access to thousands of drawn and rendered parts from more than 300 catalogs of leading global manufacturers. The downloadable 3D CAD models are compliant with the most important international standards and are available for all current CAD systems, such as: CATIA®, Autodesk® Inventor®, SolidWorks®, Creo/trade; Parametric, NX™, AutoCAD®, Solid Edge®, etc. The preview within the app provides users to rotate 3D parts and zoom.

I see at least a couple of possible classroom applications. First, these files could be used as resources when introducing basic drawing techniques such as isometric and orthographic. A teacher could select a few interesting or challenging parts for students to view and try to draw using the techniques they are learning. Second, these standard parts could become a valuable library or resources for higher level design projects. Students could use a combination of this library of parts in conjunction with their CAD system to model more advanced systems.
