When comparing Inventor® vs Fusion®, it’s important to consider the different functions of each software. Inventor is a computer-aided design (CAD) program used to create 3D models and digital prototypes, while Fusion is a 3D modeling and computer-aided manufacturing (CAM) program used for product design, engineering, and collaboration. Though both can be used for 3D modeling, Inventor is better suited for creating models from scratch, while Fusion is better for manipulating existing models.

In terms of digital prototyping, Inventor is more accurate and realistic. Fusion, meanwhile, is meant to be more flexible, intuitive, and easy to use. When it comes to collaboration, Inventor has better tools for managing versions and revisions. In terms of price, Inventor is also the more expensive of the two. This article will further compare Inventor vs. Fusion and examine the characteristics and advantages of each one.

What is Inventor?

Inventor is a software program made by Autodesk® that is used for 3D mechanical design, documentation, and simulation. The company provides annual updates with new features and enhancements being added with each release. Inventor is used by engineers and designers to create and refine three-dimensional models of physical objects. These objects can then be used in simulations to test their performance, or they can be constructed using a 3D printer or other manufacturing methods. Inventor is frequently used in the automotive and aerospace industries, as well as in other areas where precision and accuracy are essential.

What is Fusion?

Another Autodesk® product, Fusion is a powerful 3D CAD, CAM, and CAE tool that enables engineers and designers to quickly turn their ideas into products. It helps you get from concept to fabrication faster thanks to an intuitive user interface and integrated workflows. Fusion enables you to design, simulate, and fabricate your products in a single program. The software combines parametric modeling with freeform 3D sculpting and solid modeling to give you the freedom to explore your ideas and create beautiful, complex designs. With its integrated simulation and analysis tools, Fusion helps you optimize your designs for manufacturability and performance.

Inventor vs. Fusion - Use Cases and Applications

Inventor is used by engineers and product designers to create prototypes, illustrations, simulations, and animations of their products. Fusion, on the other hand, can do the same things but in a more limited scope than the more advanced Inventor. The use cases include sculpting and parametric modeling, among other capabilities. Fusion is used mostly in the architecture and engineering fields for creating three-dimensional models. It also works well for illustrations and animations of products.

Inventor vs. Fusion - System Requirement

The system requirements for Inventor are as follows:

  1. Operating System: Windows® 8.1 64-bit, Windows® 7 SP1 64-bit or Windows® 10 64-bit, macOS® 12 Monterey, macOS® 10.15.7, macOS® 11 Big Sur, or newer, Catalina 
  2. CPU: Intel® or AMD processor with 64-bit support.
  3. RAM: 8 GB, 16 GB, and 32 GB + RAM ( depending on the type of laptop)
  4. Storage: 40 GB + for installation.
  5. Graphics Card: DirectX 11 compliant, 4 GB GPU with 106 GB/S Bandwidth
  6. Browser: Google Chrome™ or equivalent

Fusion, on the other hand, has the following system requirements: 

  1. Operating System: 64-bit processor, Intel® Core i
  2. CPU: 4+ core processor, 3 GHz minimum
  3. RAM: 8 GB of RAM
  4. Storage: 5 GB available space
  5. Graphics Card: DirectX 11.0 compatible, 2GB video memory recommended
  6. Browser: Latest version of Microsoft® Edge, Safari, Google Chrome, or Firefox

What is the Operating System of Inventor and Fusion?

Inventor is only compatible with the Windows® operating system while Fusion is compatible with both Windows® and macOS®. This compatibility makes Fusion a more versatile program for users who want to use it on either type of computer.

What Are the Minimum Memory Requirements for Inventor and Fusion?

To run Inventor or Fusion smoothly, your computer will need at least 8 GB of RAM. If you have a computer with less than 8 GB of RAM, you may experience performance issues such as slow rendering times and lagging. For the best possible experience, 8 GB of RAM or more is recommended. It is also important to have a processor that is capable of handling the software (at least a 3rd generation Intel Core i5 processor or equivalent). 

What File Formats Do Inventor and Fusion Support?

Both Inventor and Fusion can import and export a wide range of file formats. This allows users to easily share data between different programs and platforms. Table 1 below shows the supported file formats for both software:

Inventor vs. Fusion - User Experience

Due to Inventor’s complexity, its user experience is not as streamlined as that of Fusion. Inventor has enough features and options to make it overwhelming for users who are not familiar with similar software. By contrast, Fusion is much more user-friendly and intuitive.

Learning Curve of Inventor and Fusion

The learning curve for both Inventor and Fusion can be quite steep but is generally milder for the latter. With a little bit of patience and perseverance, it is possible to become proficient in both programs. In terms of which program is easier to learn, it depends on the individual. In general, Fusion tends to be more user-friendly and has a more intuitive interface. Inventor, on the other hand, is more powerful and can be used to create more complex designs. Ultimately, every user’s experience comes down to personal preference and their aims for the software.

Is Inventor Easier to Learn and Use Than Fusion?

No, Inventor is not generally easier to learn than Fusion. Inventor is a parametric modeling application, while Fusion is a direct modeling application. Inventor is designed to model objects using constraints and parameters, while Fusion allows users to directly manipulate geometry without having to set up constraints or parameters. Fusion is faster and easier for some users to learn, while others may find Inventor's constraint-based modeling approach to be more intuitive.

Inventor vs. Fusion - Application Stability

When it comes to lag, crashes, and latency, both Inventor and Fusion have their fair share of issues. Lag is the delay between when you input a command and when it's executed by the software. Latency is the delay between when you input the command and when you see the results on the screen. Lag and latency can both be frustrating when working on complex designs. Crashes can also be a problem with any software, but they're especially costly in CAD applications. If your computer crashes while you're working on a design, you may lose all of your unsaved work. However, both applications are improving in these areas and as of now, there isn't a clear winner. In the end, your decision depends on your needs and which application is more stable for you.

Inventor vs. Fusion - Customer Support 

Inventor and Fusion are both Autodesk® products and users may contact customer support to resolve product-related issues. Customers can choose from phone support, email support, or web support from customer care personnel.

Inventor vs. Fusion - Community

Fusion and Inventor both offer community support, with the latter being more geared toward professionals. In addition to Autodesk® resources, there are numerous online forums for users who want to talk about issues or ideas. Blogs which post about software development topics like programming languages are also common and updated regularly.

Inventor vs. Fusion - Price

When it comes to Inventor’s cost, there are three pricing options or subscription plans available to regular users. Inventor LT is the most affordable plan and costs $50 per month. Inventor Professional comes next, costing $100 per month. The most expensive Inventor plan is Inventor Ultimate, which costs $250 per month. Fusion has a single subscription plan, and it costs $60 per month. While the monthly Inventor LT is cheaper than Fusion, it doesn’t have all of the features that are included in the Fusion subscription. It’s important to note that Inventor is only available as a monthly subscription, while you can also purchase Fusion as a yearly subscription. If you choose to go with the annual subscription for Fusion, it will cost you $495 per year, making it significantly cheaper than the monthly version.

Other Alternatives to Inventor and Fusion

Other alternatives to Inventor and Fusion are CATIA, and Solidworks®. Each piece of software has its advantages and disadvantages. It is important to choose the software that best matches your needs. CATIA, for example, is very powerful CAD software but can be difficult to learn. Solidworks® is a popular choice for many engineers and designers.
