Issues Adding Roofs

Question

Hi, 
 I'm having some problems adding roofs to my model. After extending the walls up to roof level large cutaways appear in the side of the building. I have created the roof in three parts accoring to which level it should attach to. The cutaways seem to appear on the interface between roof sections. See image for more info 
 Is this something I am doing wrong?

Hi Kfir, 
 From your screenshot, it looks like there may be two reasons for this: 
 1. Rooms that are not covered by any roof have not been excluded when setting up your roofs. For each roof, please select any irrelevant rooms as below, and then click on Set up Exposed roofs

2. You have yet to set up your intermediate floors/ceilings. This will set up the adjacencies for your internal floors and ceilings, so that the software can tell what rooms are above/below. Again, please make sure to exclude any irrelevant rooms before clicking on the Set up Intermediate floors button.
