General Information

This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert Inventor to CATIA, if you'd like to know more about the formats, please check out the following links:

Converting and Optimizing Inventor Files to CATIA

There are various ways to convert between Inventor and CATIA. With RapidPipeline, you can easily convert and and optimize Inventor files, at scale. It supports CATIA, as well as many other file formats (examples: 3dsMax, AutoCAD, Creo, FBX, glTF, Navisworks, OBJ, PLY, Revit, Solid Edge, SolidWorks, STEP, STL, USD, USDZ, VRM), at high quality.

Below you can find a video explaining how to convert your files:

What are Inventor and CATIA files commonly used for?

The Inventor file is a format mostly used for Professional 3D CAD software for mechanical design, simulation, visualization, and documentation.
The CATIA file is a format mostly used for Advanced 3D design, engineering and manufacturing applications.

0 - Basic morphing capabilities available through parametric modeling and feature-based design changes.
1 - Supports rigid body animations for mechanical assemblies, motion studies, and presentation purposes to demonstrate product functionality.
2 - Limited support for skinned animations, mainly through assembly motion simulation rather than character animation.
3 - Basic animation capabilities for assembly motion studies, presentations, and design validation rather than complex character or organic animations.
4 - CATIA supports various compression techniques for geometry data, particularly in the 3DXML format, though not as extensively as dedicated compression formats.
5 - Basic physically-based rendering material support through appearance properties for realistic visualization and presentation.
6 - Limited per-vertex color support, primarily through part coloring and display properties rather than detailed vertex color manipulation.
7 - Uses proprietary Inventor file formats but provides extensive import/export capabilities for industry standards like STEP, IGES, and other CAD formats for interoperability.
8 - While CATIA files are proprietary, the software supports many industry standards and has openly published the 3DXML format specification.
9 - Textures can be included with material definitions but with limited embedding capabilities compared to graphics-focused formats.
10 - Basic UV mapping support through material assignments, focused on mechanical visualization rather than complex mapping workflows.
11 - CATIA supports procedural materials and textures through its advanced material system, though primarily focused on engineering applications.
12 - Basic texture compression is supported, mainly for visualization and lightweight formats like 3DXML.
13 - Limited texture transformation support mainly through material properties and visual styles for presentation purposes.
14 - Basic texture mapping capabilities primarily for visualization and rendering purposes through material assignments and appearance properties.

Limitations of Inventor Files to CATIA Conversion Workflow

The following limitations should be taken into account when converting Inventor files to CATIA format:

What's the best way to get Inventor files into my 3D applications, and are there alternatives to using CATIA?

Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to Inventor and CATIA files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.

Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).

If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.

Therefore, our expertise will help you to reach your goals faster, at scale, and with the least possible friction, since we are focused on maximum interoperability.
