Like roofs themselves, there are many different variations of dormers. Dormers are roofs after all, right? There are two schools of thought here. We can add a dormer as an integral part of our roof by editing the footprint of the roof, or a dormer can be added as a separate entity altogether if needed. The objective of this video is to add an intricate dormer to the edge of our roof. We will begin with a pre-defined hip roof, and we're going to edit the footprint. We will then split the roof edge that we want the dormer on, and incorporate slope arrows to force rivet to add the dormer roof.
So to get started, let's jump into our rivet roof model or whatever model you want to have a dormer put in to. In the project browser, let's go to our roof level under Floor Plans. I want to put a dormer in this edge of this roof. To do that, I'm going to select my roof, I'm going to click Edit Footprint. Now, what we need to do is we need to split this line into three separate segments. To do that, let's click the split button right here or you can type SL.
Make sure that delete inner segment is unchecked. I want to come in about 20 feet on this side, and I'm going to come in around 20 feet on this side. I'm going to hit escape a couple times. Now, what I'm going to do is I'm going to select this line, I'm going to uncheck define slope. Now what I'm going to do is I'm going to add two slope arrows facing each other. Click on the slope arrow button, find the end point of this line and pick it.
Find the mid point of the line and go ahead and pick that. Now let's hit escape. Let's click the slope arrow button again. I'm going to pick the end point of this line, I'm going to pick the end point of the other arrow, and I'm going to hit escape. I'm going to go ahead and pick a window around these two slope arrows. Now I'm going to go to my properties tab, and I'm going to specify slope. I'm going to give it a 4-12 pitch, and I'm going to click apply. Once that's all set, go ahead and click on the green finish edit mode button, and Revit will make your dormer.
Go to a 3D view and spin around and take a look at it. If the wall's not attached already, select your wall, and you can attach top or base. So, knowing how to do this is going to be a necessary skill with either residential or commercial architecture
