inventor alternatives

Autodesk Inventor computer-aided design (CAD) software facilitates 3D mechanical design, visualization, simulation and analysis, rendering, and documentation. It has powerful features that provide designers and engineers professional-grade engineering and design solutions. Some of these features include the ability to integrate both 2D and 3D data into the same design environment, making cross-referencing and visualization easy.

It also enables the creation of virtual models, which designers and engineers can use to validate their exact dimensions, functions, and forms before manufacturing even begins. It is considered a valuable tool in CAM/CAE/CAD applications. As Scan2CAD, we’ve discussed its usefulness in several of our blog articles, including AutoCAD vs. Inventor, CATIA vs. Inventor, and SolidWorks vs. Inventor, by pitting it against other CAD software. We have also prepared an Inventor tutorial to help you navigate the user interface as well as learn the basics.

What the comparison articles made clear is the fact that Autodesk has some worthy competitors, some of which outperform it in certain applications. For instance, while Inventor makes the path to be followed when developing a 3D model from a hand-drawn concept slow and a tad difficult, SolidWorks makes it easy and fast. The same can be said about several other features, and that is why this article focuses on the top 5 inventor alternatives, which include:

Before We Start

Before we discuss the various features that make the Investor alternatives above appear on the list, let’s first briefly provide more details about Autodesk Inventor, which is easily among the most popular 3D CAD software in the market today. And that is not by accident. With a ton of features that appeal to mechanical engineers and product designers, it is easy to see the origin of the popularity. Add to this the fact that its developer, Autodesk, is a force in the CAD industry, offers more credence to Inventor’s reputation.

In terms of cost, Inventor is available in multiple packages:

  •  Monthly: $260
  • Annual: $2,085
  • 3 Years: $5,630
  • Collection: $2,720 (bundles several Autodesk products together, including AutoCAD, Inventor, Fusion 360, and more professional-grade tools)

As stated earlier, you can use Inventor for simulation and analysis. The software facilitates different types of simulations, e.g., manufacturing process (casting die press forming and molding); mechanical event and continuous event simulations; and finite element analysis (FEA), fluid analysis, and kinematic/dynamic analysis.

Nonetheless, the CAD market is competitive, and other software developers offer products with similar, if not better, features. If you are looking for such products, perhaps because the prices of the packages mentioned are too high, features aren’t appealing enough, or you simply want a non-Autodesk product, read on.
