There are two ways to create a roof for a structure:
● The Roof Face command converts any closed 2D object into a roof face object.
● The Create Roof command creates a roof object by selecting the object(s) that the roof will be based upon (including walls, polygons and polylines).
Use the Roof Face command to create hybrid (2D/3D) roof structures from any closed 2D object. This is an easy way to create a slab or flat roof. You can also use this command to create a uniquely shaped roof, such as a gable roof over a round structure. Roof faces created with this command can be connected to other roof faces; roof faces can contain elements like gables and skylights.
The Create Roof command creates a roof object with multiple faces based on specified parameters. A great variety of roof types can be created by this method, and they can include roof elements such as gables and skylights. Once the walls of a structure are complete, select the walls that the roof will be based upon, and specify the roof parameters. Alternatively, select a polygon or polyline as the basis for the roof.
The roof can be created in the same design layer as the wall structure, or in a different layer. If the walls and roof are on different layers, create a viewport to view the walls and roof together.
