What is a 3DX file?

A .3DX file is a 3D model or assembly file. Different software companies use this extension. Most commonly, it is a 3D XML model file created by Dassault Systèmes for their 3DEXPERIENCE platform. In other cases, a .3DX file is a Rhino 3D Model File created by Robert McNeel & Associates.

How to open 3DX files?

You can open Dassault .3DX files with CATIA, the 3DEXPERIENCE platform, or 3D-Tool. You can open Rhino .3DX files using Rhinoceros 3D. Because the extension has multiple meanings, you must know the exact creator software to choose the right desktop program.

Identify and view files online

If you do not know the source of your file, we recommend viewer.online/3dx to identify the actual format of the user's file. viewer.online/3dx analyzes .3DX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.

Best practices and troubleshooting

File extensions can be ambiguous. If an application fails to open your 3D model, it is likely because the file belongs to the alternative format. Inspecting the file structure is the fastest way to troubleshoot.

Summary

Because .3DX files use the known ZIP format, viewer.online/3dx can safely open and display them online, eliminating compatibility problems.
