Most real world construction projects involve massive BIM files, created using high-end workstations. Unfortunately, modern VR/AR gadgets like the Oculus Quest, Hololens and iPad have limited memory and computation power. Hence, most contemporary VR/AR apps cannot handle these large models. So you are forced to break your BIM model into smaller chunks that fit on the device!

This can be a time consuming and painful process requiring a tonne of back-and-forth experimentation to figure out a section of the model that actually works on the device. Unfortunately, since each XR device has different limitations, you need to repeat this process for different devices. Moreover, as the model gets updated, you are forced to repeat the same process for every model update. No wonder many VR/AR projects don’t go beyond the pilot stage despite the value they offer.
