TFTPad is a free 3D viewer that visualizes 3D models from TFTLabs JSON3D Gallery. Within TFTPad, interact with 3D models using the intuitive touch interface. Select a model in the public JSON3D Gallery (or among the 3 sample models installed with the application) and load it. Pinch to zoom, single finger drag to rotate, two finger drag to pan and double tap on the screen to fit all the model. To visualize your own 3D models on your device with TFTPad : - create your free account at http://json3d.tftlabs.com to get your own JSON3D Private Gallery, - upload your 3D files which will be converted to JSON3D and become ready for visualization and sharing from a Web browser or from a Mobile/Tablet with TFTPad. - whenever you are ready, transfer to public JSON3D Gallery for unrestricted sharing. As a free application, JSON3D Gallery supports only following CAD formats (up to their latest revision): - CATIA V5 / Dassault Systemes - SolidWorks / Dassault Systemes - JT / Siemens - Pro/Engineer - Creo Parametric / Parametric Technology Corporation Upload size in free JSON3D Gallery is limited to 10 Mb. TFTPad and JSON3D Gallery are part of TFTLabs line of products and technologies, focused on 3D communication and interoperability on the Web and mobile. TFTLabs products work directly on 3D data from all native or generic CAD formats (more than 20 formats) up to their latest revision. The whole technology for import and visualization is owned by TFTLabs and built upon the JSON3D file format. TFTLabs choosed JSON (JavaScript Object Notation), part of ECMAScript/Javascript ISO Standard which is the only standard for HTML5/Web applications, to build up 3D Web technology upon so-called JSON3D format. As such, JSON3D is open (textual), customizable, optimized for compressed Web transmission/usage and compatible with Mobile/Tablet.

About

AI CAD

Features
Read full description

Turn an idea into an editable CAD model using the way you naturally work: take a photo, sketch a concept, or describe what you need in plain language. AI CAD helps transform your input into practical 3D geometry that you can inspect, refine, and share. DESIGN WITH AI • Start from text, a reference photo, or a hand-drawn sketch. • Refine dimensions, features, and shapes through natural-language instructions. • Continue iterating without rebuilding the model from scratch. INSPECT YOUR MODEL • Explore your design in an interactive 3D workspace. • Switch between front, top, and side views for clearer technical inspection. • Work comfortably across both iPhone and iPad. PREPARE FOR REAL WORK • Create designs for engineering concepts, prototyping, manufacturing, and 3D printing. • Share CAD files directly with teammates or move them into your existing workflow. • Use a multilingual interface designed for global engineering teams. From the first idea to the next revision, AI CAD makes computer-aided design more direct, visual, and conversational.

Verdict

The call

The clearest difference is in-app purchases: TFTPad at none against AI CAD's 4. TFTPad also leads on iOS requirement (6.0 vs 13.0). AI CAD's advantage is update cadence (weekly vs every 6 weeks). On price, ads and device support there is nothing between them.
