CAD Exchanger Lab

CAD Exchanger Lab is a desktop application to view, explore and convert 3D CAD data across 30+ file formats. CAD Exchanger can also show properties of the model and its elements (including PMI), measure, move and rotate its parts, create sectionings and exploded views.

System requirements


  • Intel Core processor family of 64 bit architecture, or a compatible non-Intel processor;
  • Graphics card supporting OpenGL 2.1 or later.

Operating systems:

  • Microsoft Windows 8, Windows 10, and respective Windows Server versions;
  • Linux RHEL8.x, CentOS 8.x, Ubuntu 16.04, Debian 9, or other flavors based on kernel 4.4;
  • MacOS X 10.14 (Mojave) and above.

Axis orientation

Different CAD applications may use different axis orientations. CAD Exchanger uses a right-handed coordinate system. The recent CAD Exchanger versions have the "Use OY as Up axis" option. If it's enabled, the exported model will be re-oriented accordingly. It's accessible through "Menu" > "Export Settings", and currently available for the following formats: 3DPDF, Collada, FBX, gLTF, OBJ, U3D, USD.

Model size limit

As for the file size limit for CAD Exchanger Lab, technically there isn't any. There may be some limit dependent on the PCs hardware capabilities though.

Note: we recommend increasing virtual memory for better performance with bigger models on Windows. Large models can cause trouble when there isn't enough virtual memory allocated for the system to process big files, so increasing it should help processing large models. Here's how to do this:

  1. Navigate to the "System" section of the Windows Control Panel;
  2. Open "Advanced System Settings", go to the 'Advanced' tab;
  3. Click the "Settings" button under the 'Performance' section to open another window;
  4. Click on the new window's "Advanced" tab;
  5. Increase the paging file sizes to 8000-12000mb under the "Virtual Memory" section, click "Change";
  6. Restart your computer for the changes to take effect.

CAD Exchanger SDK

CAD Exchanger SDK is a set of libraries to develop 3D applications. It is written in C++, but it has a few wrappers to provide bindings with other programming languages, namely C#, Java and Python. It allows reading, accessing, exploring, analyzing and editing the contents of 3D CAD files, writing them to a number of formats, and also visualizing.
