The Ultimate
Architectural Diagramming Tool

No, you do not need to install any heavy 3D software or plugins. You can simply open Archi Diagram directly in your web browser.

Yes! We offer a powerful Free version. While it has some limitations (like a maximum of 15 placed symbols and limited sunpath months), it is absolutely not useless. The Free tier is incredibly robust and packs more than enough power to instantly generate context maps and jumpstart your professional architectural presentations.

While our beloved SketchUp plugins (Sun Diagram, Dynamic Symbols, Shadow Slice) are designed for deep, integrated modeling workflows within SketchUp, the Web App is a standalone platform focused on rapid presentation, instant map context generation, and accessibility from any device (even an iPad!).

Absolutely! You can upload your own 3D project models in .glb, .gltf, .obj, or .fbx formats (exported in Meters). Even better, once imported, you can edit materials, change colors, adjust opacity, and toggle wireframe edges directly within the Web App.

Yes, but to maintain a clean architectural aesthetic, the Web App's Dynamic Symbols library provides highly simplified, abstract versions of these elements (like ghosted trees or basic massing blocks). You can also drag and drop professional wind analysis arrows and 3D text pins to annotate your diagrams instantly.

You never have to manually rotate your 3D model! Just use the True North (North Offset) slider in the Location tab. This seamlessly rotates both the Sunpath and the precise 1:1 Satellite Map background around your fixed model, perfectly aligning the real-world map with your project's orientation.

Yes, the app handles this fully automatically! Based on your location, it detects the exact local timezone and DST rules. The UTC offset for specific months is even visually represented directly on the 3D Sun path diagram, ensuring 100% real-world accuracy for your shadow analysis.

The map uses a strict 1:1 real-world scale and loads a high-resolution 1280x1280 pixel image. To cover a larger physical radius (e.g., city scale vs. block scale), simply decrease the Zoom Level (zoom out) so that each pixel covers more real-world meters.

Absolutely. You can render and export high-quality JPGs (up to 5K resolution), PDFs, and Cinematic Video animations directly from your browser without needing any third-party rendering software.

Yes! By logging in with a Google or Email account, you can securely save your projects to the cloud. Free accounts get 10MB of storage, while Pro accounts get 100MB. You can also share your projects publicly with a simple link!
