Pixelated Architect 3D takes 2D floor plan images and turns them into 3D architecture for unity. This is by far not meant for final products it's great for a base model or prototyping. You can download the editor for free as I'm creating it at armed unity. Once it's finished, I plan to release it for free in the unity asset store. There is still alot of features to add but I thought I would show what I have done so far.
