Description

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

Requires credits to view files, have to watch ads for more credits. Don't waste your time like this developer is trying to make you do.

Developer Response

Everything in the app is free. Credits only skip the ad - you can always view files without them. We also fixed a bug where credits were deducted even when the conversion failed. Sorry for the confusion.

Install, delete. Makes you pay to look at a file. Awful stay away

v1.0.9

not working for stp files

Developer Response

Sorry about that. The latest update shows what went wrong instead of failing silently, shows progress for large files, and lets you open .step files straight from your file manager. Please try again - if it still fails, the screen now tells you why.
