RE:Improved 3D toursThe one I like is the church located in Sainte-Anne de Varennes.
Look for the ruler on the upper left side. You can measure the dimension of objects and the layout of the church. If you press on the «H» you can measure the height of the building. What is missing is a tool to calculate the area. Matterport has this tool.

It will make their life a lot easier and more productive. Hopefully, UI will be working to integrate into their floor plans the surface areas of the buildings and rooms.
