CAD Exchanger – Work with your 3D models

[App] CAD Exchanger – View & Convert 3D CAD models

CAD Exchanger  CAD Exchanger allows to view, explore, and convert 3D CAD models across 30+ key CAD formats, incl. native (SOLIDWORKS, CATIA, Siemens NX, DWG…), neutral (JT, STEP, IGES, IFC…) and kernel (Parasolid, Rhino, ACIS…) formats.

Whether you are on a shop floor, at a business meeting, or just outside your office you can still work with your 3D models and share files with your partners.

Free mobile version of CAD Exchanger complements more feature-rich commercial desktop and Cloud versions. All of them run on CAD Exchanger SDK, our own CAD formats conversion technologies which you can use to build your own 3D mobile, web and desktop apps:

Available operations with 3D CAD models:

Product structure navigation to access parts and assemblies
Basic properties editing such as color and name assignments
Switching between B-Rep and polygonal representations
Sectioning and exploded views creation
Access to basic dimensions data

Product structure navigation

Product structure navigation allows you to show or hide model’s individual parts and sub-assemblies and get instant access to the measurement information in a few taps.

Flexible view capabilities

Depending on your goals you can choose B-Rep geometry or polygonal mesh representations for your CAD drawings. You can visualize 3D models in wireframe, shading modes or combinations of the above.

Sectioning and exploded views

You can explore internal details and component layout of the models with the help of sectioning views, which allow to cut the model in several dimensions and choose the sectioning plane position. Or just visually explore your 3D model and understand the underneath of the design with a help of an exploded view.

Colors and names editing

You can assign or modify colors and names of the parts and assemblies to make your 3D model more visually appealing, easy to navigate through and for efficient BOM (Bill of Material) generation in the downstream apps.

Access to basic dimensions data

Build a bounding box of a part, an assembly or a whole model in a couple of taps. With the visual evaluation of the occupied space you will also receive accurate information including dimensions, minimum and maximum corner coordinates.

Excellent performance

CAD Exchanger is empowered with patented parallel computational algorithms. Although you can hardly work efficiently with very large 3D models on mobile devices you can still get shorter loading times and great application responsiveness.

Due to limited performance and memory of mobile devices, imported CAD files are limited in size. The list of exported formats as well as some functionality is also limited (e.g. no distance and and angular measurements are available). Desktop and cloud versions (which you can find at are free of these limitations.

We hope you will enjoy working with CAD Exchanger. If you face any issues with CAD Exchanger please contact us via support[at] We will be happy to respond and make the product better with the help of your feedback.

CAD Exchanger user reviews :

Best mobile app ever used for catia v5. Thanks for creating such a wonderful app.
  • Thanks a lot for such a positive review. We appreciate it!

It’s a really handy app. But I hope they’ll add F3d files soon

I have tried with different smartphones and now I could not export the file in another format (months ago it was working good). Is there a problem with the new update?.
  • Hello! Starting with version 3.9.1, our app has become free, however, the number of formats available for export has been reduced. To export to other formats, please use our Desktop or Cloud solutions.
All good and working, except measuring tool is missing. Though it has equiped with Box Measurement, I think a simple Point to Point mesurement tool would have added more charm.
  • Hello Aaditya. Thank you for your comment. Measurement tool is available in our Desktop and Cloud applicaiton. We are still considering adding measurements in CAD Exchanger for Android

Perfect CAD tool. Need same application to open Ansys, Abaqus, other CAE applications like Altair Hyperview.
