Is there any asset or tool to make 3D buildings/interiors?

Hello there!

I’m working on a project and I would like to create my own buildings and their respective interiors so I can
have different layers for each floor to navigate through them and show what elements they have (computers, chairs, doors and so on…).

Any help would be much appreciated, thanks!

I can recommend Construction for building creation, Octave3D for prop placement.
