STEP Viewer
Fast STEP File Viewer
Free · Designed for iPad. Not verified for macOS.
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
