What function does the 'Detail Line' serve in a Revit project?

The 'Detail Line' function in a Revit project is specifically designed to create 2D geometry that does not influence the overall model or its scheduling. This means that when you use detail lines, you can add additional annotations, symbols, or graphical elements to your views without altering the physical components of the model itself.

Detail lines are particularly useful for adding specific information to a drawing, such as reference lines, sketches, or other visual aids that enhance the clarity of the documentation. Since they are purely 2D and do not represent any physical object in the project, they will not affect calculations, schedules, or other elements that are integral to the model's performance and coordination within the Revit environment.

Using detail lines allows a designer or architect to provide important visual context without complicating the model or introducing elements that could affect performance or reporting functions of the software. This aids in maintaining a clean and manageable model while still conveying necessary information in the documentation.
