Revit Wont Cut Dormer Roof

I cant seem to select the hole to remove it.

Revit wont cut dormer roof.

The pick roof wall edges tool is active so that you can pick the boundaries that compose the dormer opening. Place the 3 walls in the plan view. When that edge on the dormer gets too close to the same edge on the main roof the opening cut fails. Place the cursor in the drawing area.

When i erase the dormer walls and roof i have the hole in my roof where the dormer was located. This tutorial explains the process to create a gable dormer in revit. I have a roof that i have cut for a major gambrel dormer that is identical on both the front and rear of the building. Change the visual style back to shaded to show the finished item as in.

If you make the dormer roof with a very slightly bigger overhang than the main roof it will then join to the main roof. Watch the status bar to be sure that you are highlighting the main roof. If so how do you do it. Is it possible to remove a cutout for a dormer in a roof with revit.

Select the dormer cut and then select the edit dormer opening from the ribbon as shown in figure 8. Next the walls need to be moved to the roof line to create the dormer. Structure tab opening panel dormer opening highlight the main roof on the building model and click to select it. You can also create the dormer with a two cut plumb and the fascia depth set to zero so that the dormer has a flat.

I made the dormers and the dormer openings the same way but on the rear of the building one line of the cut profile only seems to cut the roof in the vertical direction instead of both horizontally and vertically as all the other cut profile lines do. On the properties palette set the top constraint for the walls to unconnected and specify a height of 4000. Edit the dormer opening to reflect the roof modification as per figure 9. Select the wall tool and choose a wall from the type selector.

The dormer cut has been left selected to show the modification. It can be as little as 1 128. I want to eliminate of the dormers. If the 2 edges are far enough away from each other it works fine.
