It has been a quick change - about 20 years ago, we saw a *manual* version of LiDAR that was a one of prototype, that cost about $500K, to only a few years later having a company that used automated LiDAR to get full 3D models. Now the outside of the building can be done with 8 photos with your phone, in a few hours, and a 2 figure subscription.

Can Matterport give us CAD drawings?

Yes its amazing how much it has changed in just coupe of decades and how cheap it has become.

Matterport can export as point cloud, OBJ, 3DS and FBX format. So not a true CAD model but a mesh representation of it (DataCAD can import OBJ or 3DS files)

It still has its advantages. Here is a case study you might like: Architectural firm cuts AutoCAD as-built modeling time by 50%, is able to accommodate 15% more business:

Thanks for the link - the video shows that they only had to take overall dimensions, and they scaled the MatterPort file to match, and then traced it is CAD. They don't use the cloud of points, really. But still, very interesting leap in technology and method. MatterPort apparently stacked the plans correctly, and "found" several unexpected features in the building.
