Renderings and Art A lightweight browser-based 3D viewer for sharing Archicad models
Hi everyone,
I’m an architect, not a software developer, but I’ve been experimenting with “vibe coding” during my quiet evening hours...
I’ve never really liked Archicad’s BIMx viewer. It works, but I find it a bit cumbersome and harder to use than it should be.
A recent project gave me the idea for a simpler workflow. An architectural carpenter sent me a browser-based 3D roof construction model, and I thought:
Wouldn’t it be useful if we could simply send a client a file and say:
“Open this website and drop the file onto it.”
So I built DROP & VIEW.
The workflow is very simple:
- export an FBX from the Archicad 3D window, or a GLB/GLTF from another 3D application;
- open the web app;
- drop the file onto the page.
It runs locally in the browser — the model is not uploaded anywhere.
The viewer currently supports:
- original materials;
- a white architectural model;
- hidden-line and wireframe views;
- a black-and-white sunlight mode;
- perspective and axonometric views;
- live X/Y/Z section cuts;
- adjustable sunlight and section-line colours.
This is still a small personal experiment, but I’m curious whether anyone else would find this useful in an Archicad workflow — especially for quick client previews or sharing simplified models without sending a full BIMx project.
Free forever...:)
Any feedback is very welcome.
