Chief Architect has different software programs.

SketchUp is great. 3D views. There's a learning curve.

Capable software starts at hundreds per month, or thousands per year. Start with your floor plan on graph paper. If you can't do it with graph paper, you cannot begin to do it with software. The limitation of software is the input of the user. Using software doesn't make anyone's measurements or ideas better. It's called an architect or interior designer for better ideas that are grounded in the real world doability, with a real world budget. https://shopping.chiefarchitect.com/checkout/cart/
