Funnily enough for me, to get to sleep last night I was retracing steps in favoured levels from Team Fortress 2, which I've not played in years, and was a little concerned about how vivid my memories seemed. Useless information taking up increasingly valuable neurons... . Oh well.
Sketchup[0] is a very popular tool with architects these days. You can import those models into VR with IrisVR[1] and other tools.
We did this for our entire remodel and our architect now does the same thing when designing (after trying it out on our Vive). They also use it for their customers, both as a sales tool and to help fine tune the designs.
It's not 100% perfect (yet), but we moved and eliminated cabinets, lengthened counter tops, spaced appliances differently, etc all based on VR.
Edit: fastest downvote I've seen.
Because Columbine, that's why. In the 90s, kids used to recreate their college campuses, etc. in Doom. Then Columbine happened, and such things were viewed as possible mass-murder prep.
Doom is primitive by today's standards anyway. I hear tell Unreal Engine is sometimes used for architectural visualizations, etc.
> I'm sure there are Doom levels that I haven't played in years that I could walk round confidently [1] if they suddenly became real.
Given that Doomguy moves at approximately 50 mph, it'd take real-world you quite a bit longer to explore those real-world levels.

They just apparently did not design their HS in Doom.
What do you mean by "used Doom"?
