Detail components are pre-drawn line-based 2D elements that you can add to detail or drafting views. They are visible only in those views. They scale with the model, rather than the sheet.
For example, in the following drafting view, the studs, insulation, and siding are detail components.
Revit Architecture allows you to create a 2D detail component based on a line. By selecting the start and end of the line, you can place the detail. Suppose you want to place a plywood fill pattern in a section. By selecting the start and end points of the detail component, you can place the detail with the thickness and fill pattern that was created in the 2D detail component. For example, if the plywood is drawn at 1/2” in the 2D detail component, this procedure would place a piece of plywood along the length of the drawn line at 1/2”. If you wanted to adjust the thickness of the plywood, you would first have to edit the 2D detail component.

The following is the general procedure for creating a 2D line-based detail component family. Your steps may differ depending on your design intent.
For filled regions, select the filled region and click Modify Detail Items tabDetail panelVisibility Settings, and select the views in which the object will be visible.
