STEP View 3D

This is a great 3D STEP (ISO 10303, PDES, stp )data file viewer. Even if you use CAD software like CATIA, ProEngineer, SolidWorks, NX, etc. which might not save STEP file directly, you can certainly use the CAD software to export your model in STEP foramt and use the app to view it. With help of this app, you can take your 3D STEP files with you no matter where you are, at home or traveling abroad, and view them with your phone (or tablet) in any way you want.

The app provides many 3D features including rotating model with finger movement, zooming in/out, changing color, etc. You can also load multiple files together.

STEP data files can be added to the app's external storage folder called 'afanche'. Just connect your phone (or tablet) with a PC and copy your models to the 'afanche' folder of the device. After that, you can use the app to load the models you saved in the directory. If you have files in system 'download' folder or any other folder of your device, you can use the app to find and open them as well. You can also use the app to open files from email(attachment) or web (by downloading). The app supports third party file management app, for instance, DropBox.

The app is not just a STEP data file viewer. It is also a file organizer. You can put project files in different sub folder so that you can easily find them. The app provides you file sorting features so that you can find your model quickly. You can sort by file name or file creation time. If you need share model with your friend, coworker, client or partner, you can use in-app email feature to send your model out as email attachment.

The app also provides native support for multimedia including image, video and audio. This way, you can manage picture or video of your project and STEP files together. The app provides features for you to have a peek at the raw data of data files in ASCII (text) or binary format.

The app provides you snapshot feature so that you can take a snapshot of your 3D model, and draw your remark on it and send it to your coworkers through email.

The app is part of ATView3D 3D visualization tool family developed by Afanche Technoologies.

More info about STEP format from Wikipedia:

STEP can be used to exchange data between CAD, computer-aided manufacturing, computer-aided engineering, product data management/enterprise data modeling and other CAx systems. STEP is addressing product data from mechanical and electrical design, geometric dimensioning and tolerancing, analysis and manufacturing, with additional information specific to various industries such as automotive, aerospace, building construction, ship, oil and gas, process plants and others.
