What types of building information are best portrayed in 3D views?

• Which stakeholders require 2D views, and why?

The use of the interior space of a building and the architectural designs are best portrayed in 3D views. This allows for information that is not/cannot be conveyed in 2D views to be showcased to the intended audience. Clients are usually more interested in seeing how the space is used, which means that they usually want to use either 2D views (showing the furniture, casework, and fixtures during the preliminary design stages) or 3D views (once the design has been finalized). Contractors require 2D views because they are interested in learning how the building will be built, rather than how the space will be used.

Give examples of how the building information for a specific location in the project needs to be filtered for different audiences and purposes?

Should your design ideas always be conveyed through photorealistic renders?

• How does the level of detail in the rendering and its presentation affect the perception of stakeholders reviewing your design?

Whether or not design ideas should be conveyed through photorealistic renders depends on the intended audience of the designer and the project phase. A client will be interested in seeing a more photorealistic visual of the design, rather than a contractor. An engineer may be interested in receiving similar renders to the client depending on how your design ideas will affect their realm of responsibility on the project. For example, a structural engineer may be interested in seeing how your design will affect the structural integrity of the building (depends on the engnieer), while a geotechnical engineer may not be interested in the renderings. In the early stages of a project, the design of the building typically has not been finalized yet. This means that conveying design ideas through photorealistic renders may cause the stakeholders to feel as if the designs have been finalized. As a result, they are less inclined to provide their opinion on the designs, which means that you are not considering their honest opinions in the designs. When conveying your designs to stakeholders in the early design stages of a project, it is usually better to use less of a realistic render and more of a "sketchy" perspective (similar to an artistic sketch). This shows that designs have not been finalized, and will encourage stakeholders to provide their input.

Name some applications where viewing the building and model information in virtual reality or augmented reality would be most beneficial?

• Are there advantages to using a C.A.V.E as a virtual environment versus VR headsets?

How can schedule views be used to assist with procurement and model-based estimating?

Schedule views can be used to support procurement and model-based estimating by providing the required quantities (e.g. count and area) used to perform those calculations. In addition, schedule views can be used to organize building components based on different classifications (i.e. type, level, etc), which can be used in the cost-estimating of specific groups of building materials/members.
