Creating a roof for the porch

Now that we have the main roof over our house drawn, we now need to have a roof that’s going to cover up this front porch area as well as a little bit of the main body of the house. Let’s start by zooming in on this portion of the house. The reason why we didn’t do this all in one roof surface is the fact that this roof comes over here, comes out, and then dives in underneath the big main roof body that’s covering the majority of the home. That’s something that one roof inside of Revit just isn’t capable of doing.

It can’t curve in and wrap itself back underneath itself. It requires at least two roofs in order to be able to accomplish that task. Now our next thing that we need to do is start to draw in the outlines of where this roof is going to be covering. So to begin with, underneath the Home tab here, I’m going to be coming over and selecting on the word Roof. You can pick on the word or just on the roof. If you pick on the word, you’ll get a variety of options, including Roof by Footprint and that’s what we’ll be using.

We’re going to select the exact same Roof options that we had before with the main body of the roof, and that’s going to be a Wood Rafter 8-inch. Also make sure your Base Level’s at TOP, and the Base Offset is going to be -8 inches. Now we’re going to draw in manually each location where these lines are going to need to be, where the roof is going to need to be. So I’m going to select on the word Line right here. Next I’m going to draw in a line from right here, and I’m just going to draw it up.

I think it’s going to be a 2 feet 1 inches, just straight up here. Now in truth I might be able to just draw it up right here to this edge, it’s hard to say if that’s going to clean up the roof. I like to kind of cross them over just a little bit if they’re going to be touching, so that I know for a fact I can get these two roofs to join together at the end of the process. Next, come over and make sure that that dimension right there is currently being covered up by Intersection and Horizontal; it ends up showing up as being 2 feet.

As long as it shows up as being 2 feet, you know that you’re in the right location and you’re in a great starting point. Now this next one is going to actually have a defined slope associated with it. So it’s going to slope up from this point up and then from over here on up. But we’re going to define that slope after the fact because we can and we’ll just kind of speed this process along. I’m going to type in 10 foot 5 inches when it’s going straight down. So go ahead and type in the 10 foot 5 inches.

Next, move over to your right, 26 feet. Come straight up and tie this roof directly into the wall. So bring it right up to the wall, because that’s where it’s going to actually tie into. Now move over, and how far we want to draw this line over to the left, is going to be 13 feet. Why? Because that’s the exact middle of this roof, that 26 feet that we just drew. Now we’re going to bring this down and just have it line up with that first purple, magenta, whatever color line that is, and just make sure that it’s lining up fine.

Now we no longer need this line right here, so you can go ahead and delete this very first line that we drew. But the second line that we drew which we’ve oftentimes in the past have deleted as sort of a reference line for the spot that we’re going to be starting our drawing at; this can be of use for us because it’s in the right location already. So select on that line, grab onto the blue dot, and just pull it over. Once it’s one continuous line as you follow it around, we need to do one more thing before clicking on the big green check mark, and that is, select on this line on the left-hand side and this line on the right-hand side, and we need to define the slopes for each of those so the roof will slope up appropriately.

Once you’ve done that, just clicking over here and telling it the slope isn’t going to be quite good enough. We need to actually go in here and in each location select on the line and either click where this text is at and turn it into a 4’/12" slope or select on the line and click where this text is at and turn it into 4’/12" slope. Either one works; it’s filling in the same information, just in two different locations where it can be done. Once you finally have this together, come up to the big green check mark, and select on the big green check mark.

Now if we take a look at it in the 3D view by coming up to the little 3D house, and we spin our building around to take a look at it, You’ll see that our two roofs are now lining up, but they are crossing over each other, which means we’re going to need to join them together next. Now that’s easy enough to do. It doesn’t matter which roof you select on; just pick one of them and there’s a command up here on the Ribbon, it’s called Join. Select on the Join tool and then pick one roof, whichever one, doesn’t matter, and pick the other roof, and you’ll see, they automatically join together.

Now it’s not a perfect cleanup but it’s pretty darn close, and it’ll print out well and just look good overall whenever we’re doing presentations and that sort of work. It also takes away some of the extra little material that didn’t need to be there. Now if we spin this around a little bit more, we can see that in fact this roof does wrap in underneath the main roof, and that would have been an impossibility if we had drawn this with just one roof. Also we will come back in and actually clean up this wall, this wall, the walls on the underneath side here, as well as adding some extra structure here in order to finally finish off our front porch.
