I'm an architect and I have been building a cheap/robust 2d LiDAR setup and stumbled across this. Works great. Sometimes the Quest to PC wireless pipeline seems to freeze or lock up when refining on PC (refining on the unit fails often for large scenes) so just make sure to save your scan before refining and just reload it. For your info: using Quest 3 (latest PTC firmware from September 2026), PC has RTX 3080 32gigs ram Windows 11. Imported OBJ into 3ds Max 2027 and scaled up by 3937% to get it to real scale (mm to inch conversion).

Thanks a lot for the detailed feedback and for sharing your setup! Really glad to hear it’s working well for your architectural workflow.
The PC refining freeze with larger scenes and the OBJ scale/unit mismatch are both very useful reports. We’ll look into improving stability for large scans and making the exported scale more consistent.
Also, great tip about saving before refining, appreciate you sharing the workaround!
