BIM OOTB

Zero install. Here's what's on your machine:
Building data — cached in your browser's internal storage (IndexedDB) so buildings load instantly on repeat visits. Nothing is installed. No files on your desktop or downloads folder.
Progress — which buildings you've explored is saved in your browser (localStorage). Survives tab close.
To start fresh — Clear all cached data — removes everything, back to zero. Or just clear your browser data for this site.

This is an experimental project. Learn more at BIM Designer Browser
