Should your design ideas always be conveyed through photorealistic renders?
I think it depends on the purpose. If we are going to present the design to building contractor, the major concerns are the measurement of the size and the location of the project instead of the furniture or any other equipment in the room/ house. Then it is not necessary to show the realistic view.
If we are going to present the design to someone who are interested in the interior of the house then, more realistic view would be better.
How can schedule views be used to assist with procurement and model-based estimating?
By using the schedule views, the quantity of item could be summarized in a table and the total cost could then be calculated by custom formula.
This method allows user to have quick feedback when changing the different item of the model.
Give examples of how the building information for a specific location in the project needs to be filtered for different audiences and purposes?
One of the examples is the type of works, MEP Contractor requires fitting layout details and Civil Contractor more concerns on the structure such as wall and beam.
