CAD Exchanger: View & Convert 3D CAD data

CAD Exchanger allows to view, explore, and convert 3D CAD data across 20+ key CAD formats, including native (SOLIDWORKS, CATIA, Siemens NX, DWG, etc), neutral (JT, STEP, IGES, IFC, etc) and kernel (Parasolid, Rhino, ACIS, etc) formats.

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

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

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 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. 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 applications.

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 assemblies on mobile devices you can still get shorter loading times and great application responsiveness even on mobile devices.

Due to limited performance and memory of mobile devices, imported 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 We will be happy to respond and make the product better with the help of your feedback.
