Dreams & Diversions
My preferred way is to design by making a virtual model. Ideas can be explored , revised, refined, and evaluated for their design objectives, constructability, and cost implication.
The model is accessible by everyone, to encourage dialogs, and a flow communications.
Twenty plus years ago, it was done with hand sketches and making scaled cardboard models.
To be able to see and understand the design from different angles and points of view, how the pieces fit together and thinking things through can help make your project a real success.
