STEP Viewer opens STEP (.step, .stp) CAD files in 3D on your phone. No desktop CAD software needed. Everything is free. There are no in-app purchases. Credits only skip the ad; without credits you can still open every file after watching a short ad. Key features * Open .step and .stp files straight from your file manager - just tap the file * Measure your model: a bounding box with all three side lengths, in mm or m * Six fixed views (front, right, back, left, top, bottom), plus pinch to zoom, pan and rotate * Save the converted model as GLB whenever you need it * Large files show the estimated time and memory before conversion starts, and progress while it runs * If a file cannot be opened, the app tells you why instead of failing silently * Available in 12 languages, following your device settings Supported formats * Input: .stp, .step (STEP AP203, AP214) * Output: .glb (glTF Binary) How to use 1. Tap a .step file in your file manager, or open the app and tap the folder icon 2. Wait for the conversion - large files show progress and an estimate 3. Drag to rotate, pinch to zoom, tap the view button to switch sides License This app uses Open CASCADE Technology (LGPL-2.1). https://www.opencascade.com For questions or bug reports, please contact us by email.
