How do you create a roof using Revit?

Creating a roof in Revit is commonly accomplished by selecting the Roof tool and choosing the 'By Sketch' option. This method allows users to create custom roof shapes by sketching their outlines directly in the drawing area. The sketching approach gives users the flexibility to define various types of roofs, such as gabled, hipped, or shed roofs, according to the architectural design requirements.

When using the 'By Sketch' option, users can draw the boundary of the roof and specify the slope or pitch. This is essential for creating roofs that accurately reflect design intent, allowing for detailed customization. Additionally, once the sketch is completed, the properties of the roof can be modified to meet specific needs, making this method a powerful tool in architectural modeling.

While the other choices may involve aspects related to roofs, they do not encompass the fundamental process of creating a roof in Revit. The extrusion method is indeed one way to create certain roof forms but is not the only method available. Visibility settings are more about how elements are displayed rather than creating them, and duplicating an existing roof type can be useful for replication but does not involve the initial creative process of designing a new roof shape. Therefore, the most comprehensive and common method for creating a roof is
