Grids are the second type of datum that Revit has. They organize the project. These two reference planes right here, this one is the position of grid line A and this is the position of grid line one. And so to draw a grid, it's very important that you pay attention to the direction that you draw grids in because Revit recognizes what your first click is and what your second click is, and what that first and second click can potentially have ramifications later on in the project. So for example, if I go to "Architecture" and I click on "Grid" and then I start to draw a grid line. Now, I'm going to snap directly to this reference plane so that I know that I'm placing this grid in the correct position and... the first click that I make is essentially the tail of the grid and the second click is where the bubble occurs. Now because the grids are set up in that way on this project, you want to make sure that you're drawing all of your grids consistently in that same direction so that that bubbles all appear at the same spot.
Now, notice that this one is number one and this one is number five. This one is number five because remember, I built all of those extra grids and then I deleted them. Revit keeps track of how many grids you build and so if I want to go back and make this one number two, all I have to do is click on the five and then change that to a two. Now, if you have a lot of these grids, it can be a little tricky to draw them or it can be a little tedious to draw them one by one. So we can just copy them but before I copy them, I want to make sure we've got the two grid bubbles up here aligned. I want to make sure that I have the tails of the grids aligned which I don't. So I'm going to pull them on this point, I'm going to pull it up until I see how it has that alignment line there, then I know that the bottoms of the grids are now aligned.
Now, I can just copy the rest of the grids. So I'm going to go ahead and I'm not going to worry about dimensions right now. We're going to worry about the specific locations of these grids after we place them. So I'm just going to use the "Copy" command which is this right here. I'm going to click on "Copy" and because I had the grid already selected, it's going to just copy that but I want to do it multiple times so I'm going to click on "Multiple" right here. Now, that "Multiple" will stay selected until I close Revit. You don't have to click "Multiple" every single time. And then as I do this, you can see that it renumbers the grids or it numbers the grids sequentially.
So I know that according to the handout, I need six grids that go across the top of the project like that. But now I need to get them into the right orientation. So the first thing I'm going to do is click on "Grid 2." Now, when I click on "Grid 2," you can see it has what are called, "temporary dimensions" that appear and most of the time the temporary dimensions will go to the next adjacent grid or the next adjacent object. However, if it doesn't, if it goes to some other object... Let's say for whatever reason, I wanted to measure "Grid 2," not from "Grid 3" but from "Grid 4." I don't want to do that but just as an example. What I can do is click on that "grip" right there and just drop it on level four, and now it's measuring from "Grid 4" instead of "Grid 3." So that's just how you can use these temporary dimensions.
So now we're going to do the same thing but going in the other direction, and we're going to draw another grid. So I'm going to click on "Architecture grid" and once again, I'm going to use this reference plane so that I know exactly where the grid should go. I'm going to start over here because I want the tail to be on this side and you can see it automatically numbers it number seven because I already have six grids. So what I need to do is click on that seven and change it to capital A. Now, Revit will recognize what I'm trying to do and when I copy this, using the "Copy" command, it automatically letters it B. Temporary dimensions over here, so I'm going to click "20" and then the dimension from B to C should be 20, and then from C to D is going to be 20. Now here, E needs to go beyond D so I'm just going to click on it and drag it down, and then we'll define this as 10 feet and that establishes the grids for the project.
