CATIA vs Inventor: CAD Software Compared

There are so many computer-aided design (CAD) software developed by different companies around the world to help designers, engineers, architects, and manufacturers with product development from conceptualization, design, and engineering to manufacturing.

Although the wide variety of CAD applications provide engineers, designers, architects, and manufacturers with a wide selection of tools depending on what suits them, it sometimes requires thorough research to determine the exact CAD software they need for specific tasks. Different CAD applications have different features and tools and thus one must choose wisely which application to use.

In this guide, we shall look at CATIA vs Autodesk Inventor. We look into their history, what they are used for, who uses them as well as their major differences.  

CATIA

Developers: Dassault Systèmes

First release: 1982

Current release: CATIA P3 V5-6 R2017 SP6.0 / 2018

License type: Proprietary software 

Supported OS: Windows and UNIX

History of CATIA

CATIA is one of the leading CAD software products of Dassault Systèmes, a French company headquartered in Vélizy-Villacoublay that mainly focuses on developing CAD software for use in industries. 

The first version of CATIA, which was referred to as CATIA CADCAM, was released in 1982, a year after Dassault Systèmes acquired CADAM from IBM. At that time, it was built to only run on the UNIX operating system. In 1998 the first version that could be supported on Windows NT operating system was released.

In 2014, the company also released the 3DEXPERIENCE Platform providing a cloud version of CATIA.

CATIA was first used by AVIONS MARCEL DASSAULT, French aircraft manufacture, as a 3D modeling software and also for providing NC functions for the CADCAM software they were using. At that time it was named CATI.

After the creation of the Dassault Systèmes by Dassault and acquisition of CADCAM, that is when it was renamed CATIA.

Today CATIA is mainly used for computer-aided design (CAD), computer-aided engineering (CAE), computer-aided manufacturing (CAM), 3D modeling, and product lifecycle management (PLM). The main fields where it is used include surfacing design, shape design, electrical systems design, fluid systems design, and electronic systems design, mechanical engineering, and systems engineering.

It can also be used for collaborative engineering through its cloud service.

Who uses CATIA?

It is considered a computer-aided technologies (CAx) software that offers Engineers, designers, and original equipment manufacturers (OEMs) a software suite that they can use in 3D Product Lifecycle Management.

It is used in a wide range of industries ranging from aerospace, defense, robotics, process engineering to product and packaging design.

Some architects and structural engineers also find CATIA to be a great choice in designing buildings and other structures especially due to its rendering capabilities.

There are various CATIA products built to offer solutions in different areas. The most common products are:

  • CATIA 3DEXPERIENCE – provides a cloud service for designers and engineers.
  • CATIA V5 – addresses the needs of original equipment manufacturers (OEMs) from conceptualization to supply chain.
  • Dymola – This is used for modeling and simulation of integrated and complex systems that are used in robotics, automotive, aerospace, and process manufacturing among other industries.
  • ICEM Surf – This is used for modeling curves and explicit surface geometries to enable designers to visualize complex free-form shaped CAD models.
  • CATIA Composer – This enables designers and engineers to use existing 3D design data to create a higher quality product.
  • SFE Portfolio – This is mostly used for science-based processes.
  • Electre and Catelectre– This is used for designing electromechanical models. 

Autodesk Inventor

First release: 1999

Current release: Autodesk Inventor LT 2021

License type: Proprietary

Supported OS: Windows

History of Autodesk Inventor

Autodesk Inventor is a computer-aided design application developed by Autodesk, Inc., an American multinational software corporation, headquartered in California. The company was initially known for producing AutoCAD software, before it ventured into developing a range of other applications including Inventor, Inventor Professional, Sketchbook, Revit, 3ds Max, Fusion 360, and Maya.

After the first Inventor application was released in 1999, Autodesk embarked on refining the application and it has released several versions of Autodesk Inventor to date. Every version has a code name and comes with an added or improved feature.

If we look at Autodesk Inventor 2019, for example, its code name was ‘Zora’ and it offered improved performance for undertaking large assembly, extra features of shared view collaboration, iLogic enhancements, and expanded hole command among others.

When Autodesk Inventor 2020, whose code name was ‘Senna’ was released, it had the features of the 2019 version plus several improvements on the GUI. The 2021 version is the current version is codenamed ‘Ada’ and it has a New UI Panel, improvements on the performance when undertaking large assemblies as well as enhancements for modeling.

Inventor is one of Autodesk’s most used digital prototyping applications. It is a CAD program that allows engineers, designers, and manufacturers to design 3D mechanical models, visualize, perform simulations and documentation.

Inventor is mostly used for designing, visualizing, simulating, and analysis (e.g. FEA) mechanical or electromechanical systems. Designers who want to use Autodesk products for BIM can use Revit, which is compatible with Inventor and designers can use Inventor to design some structural parts and develop them further on Revit.

Autodesk Inventor is also very common in machining shops. It is used for making 2D and 3D representations of the parts to be machined after the design phase is completed.

Who uses Autodesk Inventor?

Autodesk Inventor is mostly used in the automotive, robotics, aeronautics, robotics, and process engineering field to design, visualize, simulate, and document. 

Therefore, it is mainly used by Mechanical engineers, Mechatronics engineers, Aeronautic Engineers, System Engineers, Robotic Engineers among other mechanical and electromechanical professionals.

It has a steeper learning curve

 

CATIA and Inventor differ largely in terms of price. Compared to Inventor, CATIA is more expensive and requires more time to learn while Inventor is less expensive and very easy to use. CATIA originated from the high end of the market and it has maintained the ability to provide engineers and designers with advanced modules. On the other hand, the Inventor has majored in making CAD design easy.

In general, the CATIA user interface looks old-fashioned compared to Inventor’s easy and user-friendly user interface. It is easier for a beginner to create any product in Autodesk Inventor than in CATIA. To perform functions in CATIA, users have to work through dialog boxes. With inventor, things are quite different since functions are logically grouped 

Another difference between CATIA and Autodesk Inventor that users can’t help to note is the fact that CATIA allows users to use both linear and non-linear workflows while Inventor only allows users to use linear workflow making it difficult for designers to use the same surface of a model multiple times without moving up the EOP and copying it.  

Dassault Systèmes does not release new versions of CATIA  as often as Autodesk does for Inventor. There is almost a new version of Inventor that is released every year. But for CATIA, it releases new versions either once or twice in a decade.
