UrbanAna - Urban Design & Planning Extension for Sketchup

Thank you for the idea. While our current focus is primarily on the urban planning aspect, we are always open to exploring new possibilities and expanding our capabilities. You can stay updated on our progress by checking our fronta.work/roadmap.
Regarding the use inside an architectural building, I recommend checking out an interesting product from SketchupLabs called SketchUp Spaces, which is currently in the public beta phase. You can apply to try it, and I think it will suit your needs.
