The project browser corresponds to a logical hierarchy of all views, schedules and sheets. There is no one way of grouping and filtering. My strategy is creating three groups:
This category includes all the views that are specifically used for deliverable documents. These views are often finalized, dimensioned, annotated, and have specific settings that should remain unchanged to ensure consistency across the deliverables.
These views are dynamic and used extensively during the daily modeling and design processes. They are not typically meant for client deliverables but are crucial for internal use and coordination.
These views allow for more flexibility in visibility settings and object styles, enabling team members to add temporary elements, annotations, or analysis overlays as needed without affecting the project's deliverable views.
This are views which are essential for quality assurance and project oversight. They are configured to display specific aspects of the project that require regular checking and verification, such as compliance with safety standards or alignment with structural requirements.
These views are to be used for checking purposes and must not be manipulated or delivered.
There are two main ways of grouping groups in Revit, by using type names or by using parameters. I prefer using parameters as they can be changed when changing view templates but other people prefer that the view type defines the grouping.
