13 Sites with Free Autodesk Inventor Models

Inventor logo, Scan2CAD logo,

Inventor is a 3D mechanical design software, by Autodesk, for product design, design communication, simulation, visualization, and documentation. Its high-grade tools facilitate the creation of parts and assemblies designs ranging from simple to very complex.

It is not uncommon for beginners to find it difficult to navigate the program to create models. Also, beginners often need a sample model in the course of their learning for practice. Furthermore, professionals may find themselves on a tight schedule and without the time to start designing complex models from the scratch. It is also possible that a designer requires the CAD model of an existing product but may not want to design it from scratch.

Coming to the rescue in all these cases are websites where you can download fully designed Inventor models for use or to edit to your specifications. Most of these sites charge for their models, but would it not be nice to get some of such models for free. 

In this article, we would be reviewing 13 sites where you can find free Autodesk Inventor models for download. The models are in ipt part, iam assembly, and other native Inventor file formats. Note that this is not a ranking article, so we won’t be comparing or listing the sites in any particular order.
