Features & Capabilities

CAD Assistant is a powerful offline viewer and converter for 3D CAD and mesh models, optimized for Android tablets and smartphones. It supports a wide range of formats including STEP, IGES, BREP for CAD models, and STL, OBJ, PLY, glTF, and JT for mesh data. Users can navigate complex assembly structures, hide or show components, inspect properties, and export models into various supported formats.

The extension offers intuitive multi-touch controls for seamless 3D manipulation, multiple viewing modes such as wireframe, shaded, and shrink views, and color-coded scalar data visualization with interactive color scales. Designed for efficient integration with Android file systems, CAD Assistant allows opening, saving, and sharing files directly from local storage or via Android apps. It requires OpenGL ES 3.0+ for optimal performance and is ideal for professionals and enthusiasts needing a robust mobile CAD viewing and conversion tool.

User Reviews

CAD Assistant is a well-regarded app for viewing 3D CAD models on Android, praised for supporting many file formats and useful features without ads. However, users report compatibility issues with the latest Android versions that prevent file opening, a somewhat confusing interface, and limitations in material differentiation in section views. Requests for feature improvements include better file saving options, enhanced material and measurement features, and improved selection controls. Overall, it's a valuable tool especially for quick mobile CAD viewing and 3D printing preparation.

Pros

Supports a wide range of 3D CAD file formats including step, igs, stl, and obj.
Useful for quick viewing and checking of 3D models on mobile devices without needing heavy CAD software.
No ads and offers many display and viewing functions such as section views and lighting control.
Helpful for 3D printing preparation and sharing models easily.
Developer is responsive and fixes issues based on user feedback.

Cons

Compatibility issues with newer Android versions, especially Android 13, causing app to not work or open certain files.
Interface can be confusing and some features lack explanation, making it challenging for new users.
Inability to differentiate materials or properly visualize connections in section views for complex assemblies.
Problems saving files to external storage like SD card and missing features like importing custom backgrounds or adding material properties for volume and weight calculations.
Limited support for some file extension variants (e.g., .stp) and difficulty selecting small parts due to picking issues.

I was using this app since last 3years. This application is every much help full, but now I am facing issue that In updated Android this application is not working... getting an popup saying that this app is not suitable for the Android 13 application is too older..will be look in this issue and fix it, this application is really helpful full for me that's why ...

This is a very good app for viewing STL files for 3D Printing. Its also great to use the Section View to see the interior of models. I was wondering if there was any chance of adding support for 3mf files from Bambu Labs printers and slicer? It would then also work with OrcaSlicer 3mf files too. Many example files are on the BL MakerWorld web site. Thanks for a great app!
