In Revit Architecture 2011 Essential Training, author Paul F. Aubin shows how to create compelling architectural designs using the modeling tools in Revit. This course covers the entire building information modeling (BIM) workflow, from design concept to publishing. It also covers navigating the Revit interface, modeling basic building features such as walls, doors and windows, working with sketch-based components such as roofs and stairs, annotating designs with dimensions and callouts, and adding 3D geometry. Exercise files are included with the course.
Construction documents incorporate many kinds of symbols. Revit has dedicated tools for text, dimension, tags, and keynotes. Any other kind of symbol we can use generic annotation families. Such families can represent any symbol where you require. Let's go ahead and have a look. I am in a file called Symbols, looking at a first floor plan, and we have a couple of symbols that are already in the file based on the template that we started with. On the Annotate tab way over at the right we can find Symbol tool, and again as I said these are just generic annotation symbols, and there is a couple of them that are loaded in here.
Let's start with the North Arrow. Pretty simple north arrow. I am just going to place that somewhere down in the corner of the drawing. Now if I click on it, you may be expecting the North Arrow to kind of actually know what direction north is, and that wouldn't be that unreasonable expectation for somebody using a program like Revit. But it turns out that North Arrow is just a generic annotation symbol. It doesn't actually have any 'smarts' built into it. So you literally have to select it, go to rotate, and then put in some sort of an angle here for whatever north is.
So let's say that north was 20 degrees. We just put in 20 degrees and we press Enter. Now it turns out that when you click the Symbol tool, there actually is an option here where you can check say Rotate after placement. That takes you right into the Rotation option after you place a symbol. Okay, let's look at another example. Let's look at the Centerline symbol, a really simple symbol. I am going to kind of place it over here towards the top of the plan, click Modify, zoom in, like so.
So we've got these two dimensions here where it's an equal dimension. Let's go ahead and select this symbol. We will click Rotate again. Type in 90 degrees, and then use the little move handle that's on there and just drag it like so, and that tells us we've got a Centerline right there. I am going to do ZF for Zoom to Fit. So there aren't anymore currently in this project. So we will go over here to the Insert tab, and we will click on Load Family. That takes us to our Library folder like we've seen in previous movies, and I am going to go to the Annotations folder, and scroll down a little bit.
We'll get a couple of graphic scales right here. I am going to go ahead and choose this one, 1-8. Click Open. Go back over to my Annotate tab, click on the Symbol tool, see the Graphic Scale is listed there, and I will go ahead and place it right about here. Now it's a little tough to judge the actual scale here, but if you zoom in on this, if we were to actually measure these points, it is accurately telling us the distance.
Let me go ahead and Zoom Previous. And it might be easier to kind of see if we go ahead and open up our Floor Plan sheet. So here is our Floor Plan sheet. We will zoom in. This is our first floor plan, and you can kind to see the graphic scale there with the north arrow. So it looks a little better in context when you see it surrounded by the rest of the drawing and how it sits on the sheet. It makes a little bit more sense. So those are just some different symbols that we can add in to our projects.
If you don't have a 'smart' symbol for the test that you are trying to do, you can basically create these generic annotations which again they are not terribly smart, in the sense that they don't react to things and they aren'y linked to anything, but they do the job of giving us symbol that we need. There are a few other types of items that you might want to look at. We've got Spot Elevations, Spot Coordinates, and even Slope symbols. So no computer design program would be complete without the ability to add various symbols required by architectural documentation and Revit is no exception.
In this movie we saw just a few simple examples of the Symbol tool in action, and we can use those to put the finishing touches on our various drawings and plans.
