🚀 Big Update: Faster Loads, Smaller Files!
Our latest update is ready — the new GBKF1000 format is now fully integrated into our CAD Viewer.
✅ Load times are significantly faster
✅ Tests show up to 90% smaller file sizes
✅ No action needed — it's all automatic
⚠️ Note: OBJ support was temporarily disabled during the migration. It’ll be back soon.
Enjoy the upgrade — more improvements are on the way!
We're thrilled to share the first prototype of our custom CAD binary format (GBKF1000), designed to reduce file sizes by up to 80% and improve loading times in our WebGL viewer.
Also, As part of our commitment to open source, we're also releasing parts of the project as free software:
GBKF Core specification: https://rsm92.dev/gbkf
C++ library: https://github.com/rsm-gh/gbkf-core-cpp
Python library: https://github.com/rsm-gh/gbkf-core-python
We’ve updated our domain! You may not notice at first, but we’ve moved from www.cad-viewer.org to cad-viewer.org.
This change helps us deliver cleaner, simpler URLs—since the "www" prefix is not necessary.
We apologize if you’ve recently experienced any connection issues. Over the past two days, we’ve been upgrading our infrastructure to support HTTP/3 and IPv6 — bringing faster performance, improved reliability, and future-proof connectivity.
