Do you find the value of VR/AR to be in the communication of design intent to clients unfamiliar with traditional 2D representations, or do your designers leverage VR/AR during the design development process as well?

Absolutely both. Internally, we'll model something, move an element, etc., and we're able to evaluate the idea until it feels right.

For clients, I don't know any other way at this point. Showing a novice a 2D elevation does nothing for them. They will nod, make comments, and play along, but until you sketch a person into the drawing, they don't even understand that the front door is ten feet tall.
