Views, Sheets, and Documentation
Views are the backbone of Revit documentation. Know the view types (floor plan, reflected ceiling plan, section, elevation, 3D, drafting, legend, schedule) and how view templates apply standardized visibility settings to many views at once. View range (top, cut plane, bottom, view depth) controls what a plan shows; the cut plane is the most tested setting because it determines whether doors and windows appear.
Sheets are compositions of views placed on a titleblock. A view placed on a sheet is a view port; it can be activated for editing but that is usually a bad habit. Callouts, section marks, and elevation markers create new views and are linked to the parent. Scope boxes control the crop of multiple views at once.
Traps: a view can be on only one sheet at a time unless it is a dependent view. Duplicate vs. Duplicate with Detailing vs. Duplicate as Dependent are three different results; dependent views share the model but not annotations. Crop region and annotation crop are separate. Revisions are tracked in the Sheet Issues dialog and appear in a revision schedule on the titleblock.
Rule of thumb: if two views must show the same model with different annotation, use Duplicate with Detailing; if they must stay in sync as parts of one large plan, use Dependent.
Worked example: a section marker placed in a plan does not appear on the sheet. Check whether the section was placed but its view was never dragged onto a sheet, and whether the marker's visibility is controlled by the view template.
