Show HN: Overlay map tiles onto Autodesk's 3D BIM Viewer

gubets — Tue, 24 Mar 2026 08:59:46 +0000

https://github.com/infra-plan/bim-tile-overlay

We manage infrastructure using BIM models in Autodesk Viewer. We needed to show aerial imagery and street maps underneath the 3D models, synced to the camera in real-time, so that we can give some context to the shown infrastructure.

The hard part: coordinate transforms. A Revit model's internal coordinates are in feet, rotated, translated, and offset from a local CRS projection, which itself needs to be converted from WGS84. The library ray-casts the camera frustum onto a ground plane, converts the hit points to lon/lat, determines which XYZ tiles to fetch, stitches them into a canvas, and maps the result onto a THREE.js plane, all updating on camera change. ~500 lines of JavaScript, MIT license, one peer dependency (proj4).

We would love to hear community feedback! The reason we decided to open-source is quite common: we couldn't find something similar to this that would not require a significant change to our workflow.

Hope others will find benefit from this library.

Show HN: Pure Rust IFC/BIM Viewer in the Browser via WebAssembly

holg — Mon, 02 Mar 2026 09:56:54 +0000

I built an IFC building model viewer entirely in Rust — Leptos for the UI, Bevy for 3D rendering (WebGPU/WebGL2), parser. It compiles to a single WASM binary (~5.8MB Brotli), no C++ geometry kernel or JS runtime involved.

  The demo loads the BayArena stadium with 324 floodlights carrying real EULUMDAT photometric data embedded in the IFC file.

Click any fixture to see its polar light distribution, beam angles, and color temperature. Press L to toggle photometric lighting mode it spawns actual light sources derived from the fixture data. Source at https://github.com/holg/bimifc

Tad – Free early stage BIM software for architects

limenleap — Tue, 05 Mar 2019 14:25:34 +0000

I would appreciate if architects (of the building variety)use TAD free from www.teamtad.com It is a very different approach from conventional BIM software; and it was in use since 1989. I would deeply appreciate any feedback. Thanks!
