Wondering if there is any software to help planning divisions in a specific building (in this case a school/University), their dimensions, objects inside/inventory (such as tables, chairs,...).
Ideally, but not limited to, the following requirements:
3D, but 2D would also do the work. It would be helpful that one could define the location of, let's say, a desk and a chair in a specific division.
OpenSource.
Ease of use, or relatively low learning curve.
I believe that with the architectural plan of the building I could do this in Blender/Unity/Unreal, but I am looking for something less time consuming.
