Reconstruction of building

Hello,
First of all thank you for the amazing work and making it public. I have a small question. I was experimenting with CoreNet for building reconstruction and none of the saved models worked. So, I just wanted to know that whether have you used any of the building data available in ShapeNet for training any of the models? And if not, then if I want to have a model that reconstructs buildings from images, do I need to take care or change any specific part of the code, except for creating a building dataset?
Thank you
