So far I have made several scrap models, and sketched numerous pages of concept ideas. I have moved on to construct a quick digital using Rhino. The model is a rough idea of what my final building is going to look like.
What should I upload in this Develop Solutions step?
Consider uploading images (JPG, GIF) of your rough digital model. It's ok if your model is still a work in progress. Show an axonometric or perspective view with people, which will help others understand the scale of your library.
