Selecting attic
You can select this function when you are adding the eave line of a basic roof. Set the roof parameters in a database view.
Basic roof
Normally, you do not select the structure and parameters of a basic roof until you add the roof. In this case, you can use the parameters to define the eave height. In special cases, you can select the roof parameters already when adding the eave line. An example of such a special case is a hip roof with slopes of different pitches. In this case, you need to use the function to define the eave overhang on different slopes.
