A view is a collection of models and 3D views, that have been combined into and saved as a group. Views are useful as they enable model review, clash detection, and issue resolution to be carried out using a smaller subset of data from a coordination space, such as a specific floor of a building. In addition to combining whole models to create views, model property filters can be used to select only specific model elements, letting you focus on an even more specific area, further increasing the efficiency of your review processes.
