CAD Exchanger for PC

You're halfway through designing a part in your workshop when a client calls with questions about a file format you don't recognize. CAD Exchanger turns your computer into a workspace where you can view, navigate, and convert 3D models across dozens of formats (STEP, IGES, STL, and more) without expensive software licenses. The app handles product structures, measurement data, and internal geometry exploration, giving engineers and designers a practical alternative for file work beyond mobile devices.

CAD Exchanger for Windows PC brings the mobile app's core strengths to your desk: a streamlined interface for viewing complex 3D assemblies, flexible rendering modes, and format conversion across professional CAD standards. When you're processing files from clients, preparing presentations, or exploring exotic file types, the desktop version lets you work with your models in a persistent workspace alongside your other tools.

Viewing and Exploring 3D Models

CAD Exchanger opens files in multiple formats and displays them in wireframe, shading, or hybrid modes depending on your needs. The product structure panel lets you toggle individual parts and assemblies on and off, giving you control over what appears on screen. You can measure bounding boxes and retrieve dimensional data (minimum and maximum coordinates) for any part or the entire assembly in a few clicks. This CAD viewer and converter approach means you stay within one application instead of juggling specialized software.

Converting Between Formats

The app's conversion engine handles STEP, IGES, ACIS, Parasolid, JT, STL, VRML, X3D, and B-Rep files. Users report success converting between standard formats and importing less common types like .catproduct files, then exporting them as STEP or other readable standards. This capability appeals to hobbyist engineers and professionals who encounter proprietary formats without the full design suite installed. File size limits exist, so very large assemblies may require desktop-specific tools, but routine conversions work smoothly.

Sectioning and Internal Details

The clipping tool lets you cut models along multiple dimensions and position the sectioning plane to examine internal components and layouts. This feature helps you understand assembly logic, routing, and part relationships without disassembling the model. While users note that sectioning precision is approximate, support for slice through a model to see what's inside is useful for design review and troubleshooting, especially when sitting at your computer with time for detailed exploration.

Comparison with Mobile-Only Solutions

Onshape mobile CAD and similar remote viewers offer portability, but CAD Exchanger on PC provides a larger workspace, standard keyboard input, and persistent session management. Hobbyists and small-team designers often find the desktop version strikes a balance between cost and capability, letting you avoid monthly subscriptions for mainstream CAD platforms while retaining access to a broad range of file formats on your own hardware.
