I would like to know if I can do this with Unity:

Can I create a visualization software where a user could create a room, change the size of walls, add models that are inside a database?

Thanks.

Sure thing. If the database of models is built into your app, then it’s simple. If you want to load external models, then it’s a lot trickier, since you’ll need to write a parser to load some 3D format.
