Create 3D rendered view of a 2D floor plan
It is very useful that Visio can create 2D floor plans, import CAD drawings, and link Excel data to shapes.
However, a greater functionality would be including a view window (or separate windows with URL for posting in SharePoint site) showing the 3D rendered model of the 2D floor plan.
Here is an example from another software company.

We were promised this once, https://bvisual.net/2018/09/28/immersive-mixedreality-is-coming-to-visio/, but I think Microsoft need more people to vote for this before they can will bring it to market!
