Abstract: Aspects of the present disclosure relate to a virtual collaboration environment. In examples, a collaborator accesses the virtual collaboration environment using an extended reality device (e.g., an AR or VR headset). Properties may be presented within the virtual collaboration environment.  For example, a three-dimensional model may be viewed from various angles and at varying distances. Further, properties may be updated during a collaboration session (e.g., using a computer-aided design application). In some instances, the perspective of a collaborator may be shared with other collaborators, thereby enabling the other collaborators to perceive properties from the same or a similar perspective. As another example, a collaboration session may be recorded, such that the session may be viewed at a later point in time. The recording may enable a collaborator to move freely within the virtual collaboration space and/or from the perspective of other collaborators that were present during the recording.
