A simple idea, when navigating the model, keymap WASD keys to allow for 'flying' around the model.
I would imagine that there are lot of developers like myself who have a hobby in video games and this would be an intuitive feature to add to Infraworks.
In that same vein, it would be great if you could add a digital avatar in 3rd person to quickly navigate the environment. It would help a great deal in evaluating the proposal from the perspective of an individual user, helping UX designers provide a better product. I would look to a product like UE4, a game design engine for a great example of this.
As a premier developer of design software to create games and simulations, you should really look towards those products for ideas on how to better improve the user process.
