It's unclear from the article what Gravity Sketch offers that absolutely requires VR to get the several orders of magnitude improvement that is claimed:
> "If you wanted to make an interior and an exterior, you're still talking months," versus approximately 20 hours in the VR tool, he says.
If Gravity Sketch were on a traditional 2D screen instead of in VR, would the designers still accomplish in hours what used to take months? Conversely, if the VR visualization were to be added to the tools and processes that currently take months to prototype a model, would a similar boost in productivity be observed?
