Convert Surfaces into Volumes

After the sketch roof has been edited as desired, the surface of the sketch roof is converted into a roof volume. After this, the roof becomes a packed basic volume that can be managed with regular roof functions. Sketching functions, on the other hand, are no longer available. A sketch roof is converted into a roof volume such that the sketch surface becomes the top surface of the basic volume.

1. Select the sketch roof.
2. Right-click to open the context-sensitive menu.
3. Select Convert Surfaces to Roofs.
