FormIt

FormIt is an architectural modeling software that enables you to sketch, collaborate, analyze, and revise early-stage design concepts.

You can design with your team in the same model, in real-time, visualize the solar impact of heat gain on the surfaces of your model, create beautiful visualizations with the Autodesk standard material library, and more. Also, the program supports iteration with Revit to connect your design concepts to BIM without remodeling.
