Join Paul F. Aubin for an in-depth discussion in this video Adding columns, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] In this movie we'll discuss both architectural and structural columns and add them to our building layout. Now, we have some column grids already in the project, and these were set up and positioned in the previous few movies. And what we're gonna do is, use those to help us position where the columns need to go within this project. Now, as I said, Revit has two kinds of columns for us to choose from. So, if you look at your Architecture tab, there's a drop-down here on the Column button, and we can either create structural columns or architectural columns.
I'm gonna show them both to you, and I'm gonna start with the architectural column. Now usually when you place a model element, one of the first things you wanna do is go over to the Properties palette and look at the type selector. So here at the top of the Properties palette, on the type selector, there's a drop-down, and you can see that we have a single family currently loaded in this project called Rectangular Column. That family contains three sizes. Now, I'm gonna select the default size of 24" x 24" column, but you could certainly choose one of the other sizes if you like.
Now, you can place columns anywhere in space. I could click to place it free-standing, completely in the middle of the space if I wanted to. But if you look again at the Properties palette, you'll notice that the, under Constraints, the first check mark says Moves With Grids, and that's checked. And that's a good thing to keep checked because what'll happen is, if you snap it directly to the intersection of some existing column grids, and then I'll click my Modify tool to cancel or press Escape twice. Now, I'll show you what happens if we move one of these grids.
Notice that if I move either grid 3 or B, it will move the position of the column as well. So that's what they mean by Moves With Grids. Let me do Control + Z to undo that, and let me select these two columns and delete them. So let's place some columns a little bit more carefully now. So back to Architectural Column. And one other additional feature that is really useful when placing architectural columns is, that if you happen to be nearby existing wall geometry, then when you place that column, the column will actually merge into the surrounding wall geometry.
So what I'm gonna do is just place several of these columns at the perimeter of the building, at each of the grid intersections, and then when I'm done I'll click the Modify tool to cancel. So now I have an architectural column at the perimeter of the building going all the way around. Now, the best way to think about the architectural column is it's really like the column wrap or the enclosure around the structural column. So, it's not required that you do both structural and architectural columns, but I like to because I like to think of the architectural column as the finished drywall or the other finished materials that are surrounding the column.
And then, the structural column is the steel and the concrete that's actually holding up the building. Now I have another file here that I wanna show you what it'll look like when later we get things more refined. Here, I have a brick wall. Here is an architectural column, and here is a structural column. And this architectural column is merging into the two surrounding walls as you can see, but notice that it's actually inheriting the materials as it moves around the shape of the column. So this is what I mean by the architectural column is really kind of like a column wrap enclosure.
So let's continue placing the columns, and we'll go to structural columns next. So, if I go to the drop-down here, choose the Structural Column command, you're gonna see the column appear on you cursor. And we have some similar controls to what we had in the architectural columns. We have a type selector here. This time we have a W-Wide Flange-Column that's in our W-shape, and there's two different sizes, a 10X49 and a 10X33. I'll just accept the default of 10X49. Moves With Grids is available here, and it's already checked, just like the architectural column.
So, if you place at the intersection of two grids, then that grid will control the position of those columns. If you look at the Options bar, there are some options for Height. Now, often it will default to Depth, meaning that the level you're on will actually be the top of the column, and it will draw it going down from the current level. And that can be a little frustrating because then, it will prompt you that you can't see the column. So, I'm going to change this to Height, and then I'm gonna tell it to go up to Level 2.
Now if you wanted, you could choose any of the other levels here. So it could go up to Level 2, it could go up to the Roof, or you could even set it to Unconnected, and put in whatever value you want it to be. But in this case, I wanted to go up to Level 2, and that way if later we move the height of Level 2, it'll also change the height of the columns. Now once again, you could click and place these one-at-a-time on the screen, but with structural columns there's a faster way. Over on the right side of the ribbon, you have a Multiple panel, and on that panel are two Multiple placement options.
This one on the right is At Architectural Columns. So I'm gonna choose that, click and hold down my mouse, and drag from left to right. Notice that before I let go of the mouse, it's highlighting only the architectural columns within that selection window. And when I release the mouse, it will ghost in a small piece of steel at each of those locations. Assuming I'm satisfied with that selection, I click this green Finish check-box right here to complete the modification, and I now have a structural column at the location of each of my architectural columns.
Now the other placement option is At Grids. So here, you do a crossing selection instead, right to left. And any grid that it touches will be selected. And here it will find the two grid intersections between those sets of grids. And assuming that I'm happy with those placement options, I click Finish, and it places those pieces of steel. Now I'm gonna click Modify to cancel the command and show you one last feature. Structural columns have direction because of this eye shape.
So we could run the eye running vertically or horizontally. Well, the architectural columns, it didn't matter because they were square. Well, when an object has direction, if you tap the Spacebar, it will re-orient that direction in 90-degree increments. So, that's the easy way to flip those columns and run them in the other direction. So, we have both architectural and structural columns, and it's possible to use only one or the other. But I like to use both in my projects because, as I said, I like to use the structural columns for the actual structural material that's holding up the building, and the architectural columns for the wrap and the enclosure that finishes out the architecture.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
