Question
A
A dormer is basically only another roof attached to an existing roof. You can create the opening in the roof with the Opening command in the Modelling menu.
Use the following steps:
- Create a model with an attached roof as a dormer and with walls attached to the dormer.
- Go to a plan view where you can see both the dormer and the attached walls.
- In the Modelling menu select Opening...
- In the resulting dialog box, select 'Pick a roof to be cut by a dormer opening'.
- Pick a roof in which you want to make an opening.
Revit will switch to the sketch mode and prompts to select the boundaries for the opening. Valid boundaries are - the attached roof, wall faces and model lines. In this case we select the wall faces and the attached roof.
- Select Finish boundary.
