eDrawings® is the only CAD viewer on iPad, iPad mini, iPhone and iPod Touch that allows you to view native eDrawings files as well as native SolidWorks® parts, assemblies and drawings files. In addition, eDrawings allows convenient viewing of DWG and DXF files. eDrawings includes Augmented Reality (AR). This allows you to view your 3D models in 1:1 scale into the real world. By simply activating the device’s camera, you can bring your virtual 3D designs in a real context and see them in situ, sitting on your desk or on your conference room table or even in the palm of your hand, through your iPad, Pad mini, iPhone or iPod Touch’s screen. Move around the room and see your design from any perspective. eDrawings is the email-enabled communication tool that dramatically eases sharing of product design information. You can load and send files via email to collaborate more effectively with everyone involved in product development, including people who are not regular CAD software users to interpret and understand 2D and 3D designs. Multi-touch gestures let you pan, zoom, and rotate models easily. eDrawings also supports configurations, drawing sheets, and exploded views for eDrawings files published from SolidWorks® and all other supported CAD software.

Features
Read full 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.
