For my purpose I am designing a large structure (Old Barn that recently collapsed) and will be doing all the wiring myself. Gaining perspective on the wiring paths will help me create an electrical schedule. It's mostly a visual aid for myself so I can plan all my circuits out. Will be creating a networked smart-home assignment to manage the detached structure from my home. It may be a virtual structure to you but it is an actual project for me, complete with building documents.
