Explore the process of creating detailed roof annotations and quality controls in architectural design software. This article discusses how to use the annotate tab to define roof characteristics, calculate slope values, and identify key points such as drains and parapets.
Key Insights
- The annotate tab in architectural design software can be used to add detailed roof annotations including slope and elevation points, providing a detailed understanding of the roof's structure.
- Annotations can also serve as a quality control mechanism by identifying any areas of the roof without slope, helping avoid flat spots on the roof.
- Through spot elevations, it's possible to identify key points on the roof, such as drains and parapets, which can be essential in areas with height restrictions.

The next thing I want to do with the roof is I want to go in and add some roof annotations. So I'm going to jump back to my roof plan, and now we can see the different valley and ridge lines in here. And one of the things that we can do is we can use from our Annotate tab, we can use both Spot Elevation and Spot Slope to define some of the things that we have on our roof.
So I can go to Spot Slope here, and as you see, I can go through and I can add some of these values. And one of the things that comes up a lot is everybody wants to know how we arrived at that location for the eight inches, and it's simply by calculating the quarter inch slope on the valley. And so I just took this dimension from this intersection to this intersection and multiplied that times 0.25. So this dimension in feet times 0.25, and that gives you the rise that's required over this run.
So for our annotations, we'll go ahead and we'll just add these in here. And you can see it automatically does it for you. So this is pretty great.
It's also an excellent way to get a little bit of quality control on your roof slopes, because it'll identify if there's no slope along a point here. And so you can easily avoid having any flat spots on your roof. So that's adding the slopes to the roof.
Then I can add my Spot Elevations. And what's cool with these is I can actually determine where they're based upon. So it says current level, I can have it based upon the top or the bottom.

So I can identify the finished roof surface or the top of steel surface, which would be the bottom elevation of the roof, or I can show both. In this case, we'll just go with the selected elevation. So I could say select this point here, right, which is our ridge.
And I can add that point. And I'll just move this over a little bit to kind of clean it up for our dimension there. And so this is our ridge.
And we can add values in our properties here. You can see that we have a suffix value or a prefix value that we can add to this. If I wanted to add more descriptions, I have tons of options in there.
If I do the same thing, say, at one of our drain locations, you can see I can now identify the drain location at each of these points. And so I'll go ahead and add that tag there at each of our low points. And it's just a matter of going in, clicking, adjusting the tag a little bit so the entire text fits in there.
And we can do that at those locations. We can set our high points. What's cool is you can even set, you know, this is our Top of Parapet, which is important, especially if you're in an area that has height restrictions.
This will be something that your building official is going to want to see for sure. And it's pretty simple to add. Another thing is this arrow is not set in stone.
We can always change that annotation to have a different leader on there. If I went to edit type, you can see that Leader Arrowhead is a specific option here. And so I can change that to something else, like, say, Dot Filled 1/16".
And it goes from being an arrow to a dot, which is probably more appropriate for this use. And now we have a roof plan that's been annotated in not very much time.
