RoofsRoofsThere are three 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 objects that the roof will be based upon (including walls, polygons, and polylines).
● The Slab tool can be used to create a flat roof.
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 can be connected to other roof faces, can be connected to a set of walls after creation, and can contain dormers and skylights.
The Create Roof command creates a roof object with multiple faces based on specified parameters, and associated with a set of walls. A great variety of roof types can be created by this method, and they can include dormers 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 Slab tool creates a flat roof that can be drawn manually or by association with existing walls. When used in conjunction with the Slab Drainage tool, the resulting flat roof can have appropriate roof slopes, valley lines, and drains.
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.
Roof objects and roof faces include the ability to define roof components, associate roofs with walls and configure geometry clipping, and specify the section view where roofs and walls meet. The roof appearance and properties can be saved as a roof style.
