I'm new at this software, Home Designer Pro 2020, and I need someone to guide me to get a room layout in this odd shape. I manage to do the outside wall, for some reason I cannot upload the .plan file so I upload a .dwg file, I cannot change that shape. This is gonna be a two family under the same roof, 3fl and roof as a 4th fl. I have the ideas in my head, I just don't have the knowledge enough in this software. Could someone guide me or give me some ideas on how to proceed from this point onward? I've attached what I did so far, and pictures of what I want to achieve, thank you for your help in advance.
