Join Paul F. Aubin for an in-depth discussion in this video Creating wall sweeps and reveals, part of Revit 2018: Essential Training for Architecture (Imperial).
In this movie we're gonna look at sweeps and reveals. Sweeps are material that you add to a wall and reveals are material that you carve away from the wall. They both use a special family called a profile family which is just a 2D shape that defines the shape of the material you either wanna add or carve away, and then the length, or height of the wall, is actually used to determine the extent of the effect. We can add sweeps and reveals to the type of wall, which means it would apply everywhere that type is used, or we can actually apply it wall-by-wall.
So in this movie we'll look at examples of both conditions. So, to get started I'm gonna do a type based sweep and add a Soldier Course to my exterior walls. So all I have to do is select any one of my exterior walls, there all using the same type right now, so I'm gonna select this one right here, and go to Edit Type. Here in the Type Properties Dialogue, I next need to go to the Edit button next to Structure and I wanna get to the sweeps button down here, but I noticed that it's grayed out. So right here there's a small clue, It says Modify Vertical Structure, and then it says Section Preview Only so what that means is we need to first click the little preview button here to turn on a preview and you need to make sure that it's a Section Preview, so if it's a floor plan, Sweeps wouldn't be available.
But if it's Section, then those buttons are available. So, just make sure you do both of those things in order to access that button. The height of the preview that you see there is controlled by this sample height parameter right here, so I'm gonna drop that down a little bit, and make it 10 feet. And then I'm gonna Right click anywhere in this preview window and choose Zoom to Fit, and that just allows me to zoom in a little bit closer to see what we're doing here. Let's click the Sweeps button, and I'm gonna move it out of the way so that I can see the preview in the background as I work.
So you may recall that I said a Sweep uses a Profile. A Profile is just a 2D shape thats drawn to create the actual shape of the object that we wanna sweep. So, if you click the add button here, the profile is the first thing you wanna configure. And you'll see here a list of profile shapes that were loaded with this project when we first started it, and you've got things like Vinyl Base, and parapet caps, and down here toward the bottom, we have some soldier courses. so that's the one I'm gonna choose.
I'm gonna choose this very bottom-most one here, Wall Sweep, Soldier Course, three bricks Now, if the profile you want isn't on the list, you can click the load profile button here, and load one in from the hard drive. So, I've got the profile, let's click apply and see what happens. Notice it just drops that sweep in right down at the bottom of the wall. The reason for that is the from option here has two choices, and it's either base or top. If I chose top, it would put it at the top of wall. Well, I think base makes more sense in this case so I'll leave it there, but I wanna configure a distance to move it up of off the bottom of the wall there.
So I'm gonna put in six for six feet and click apply and that will move it up. That's gettin' it a little bit better but there's still some more that we have to do to it. Let's address the material next, it's currently set to By Category but if you click in there a small browse button appears. I can click that, that opens up the material browser, and then at the top I'll start typing in soldier. When I do a single material will appear, Brick Soldier Course, you can see it uses a vertical brick pattern. I'll click OK and now when we look at this thing in elevation, it will have the brick pattern applied to it.
Now the sweep is currently hanging off the outside face of the wall. So let's deal with that next. Right here, we've got an off-set parameter and you can put in either a positive or negative number. We wanna put in the thickness of the brick here. Now if we move the sweeps dialogue out of the way, the thickness of that material is three and 5/8. If you look carefully at the profile it looks like slightly thinner than that. Let's try maybe three and a half inches here. When I enter that and click apply, that actually move it further away from the wall.
Why don't we click right in front of that and add a minus sign and then click apply again, and that will do a better job and kind of push it right into the wall there. And of course you can fine tune that more if you like. At that point we're kinda configured the way that we need to go. Let's go ahead and click OK. And then I'll click OK again to see the result. One more time, and you'll see that the Soldier Course gets applied not only to the wall that we have selected but it gets applied to all of the exterior walls. If you look the windows, it looks a little odd.
So it's actually starting and stopping after each window. Let me edit Type again, go back to Edit Structure and there was one more setting that we wanted to do here in sweeps. So when I click the sweeps button, we can tell it to be cuttable. What that means is that it'll actually allow the windows to kind of notch in and around, so let me click OK, OK again, one more time, and now you'll see that the Soldier Course will go across the tops of the doors and window, but it will cut a notch in to receive those windows, and I think that looks a little bit nicer.
The only problem with this is that this small piece of wall here, which actually starts up on the second floor, is also getting that Sweep. And we probably don't want it there. The solution is quite simple, select the wall, edit Type, duplicate it, and give it a custom name. I'm gonna say No Sweep at the end of the name here. Go to edit Structure, Sweeps, select my sweep here, and just remove it, click the Delete button, click OK, OK, OK again, and now that will remove the Sweep just from that instance of the wall, but it stays everywhere else.
That's a Type based Sweep. The main advantage of it as you can see, is you only need to apply it at the type level and it appears everywhere. Sometimes you don't want the sweep to appear on all instances of the wall, so you might choose to add it directly to the individual walls instead. Well, if you go to the Wall Drop-down, we have Wall Sweep, and Wall Reveal, and both of these options would allow you to add the Sweeps and Reveals to just the individual walls you select. We've already done Sweep, so let's do Reveal in this case.
And if you look at the preview window here you can kinda see what the Reveal is gonna do. It also uses a Profile Shape, but now instead of adding the Profile Shape to the wall, it actually subtracts that volume from the walls, so it's gonna carve away. You can do reveals at the type level as well. If I edit Type on this wall, edit Structure, Reveals is available here and the dialogue looks very similar. I'm gonna cancel outta there. In this case I'm gonna do the Reveal directly on a wall-by-wall basis, and there's only one Reveal choice currently in the project, I'm gonna just accept that, but if you did edit Type you could duplicate and choose a different Profile.
The Profile we're gonna be using is just a simple square Profile. Notice that here, unlike the type based sweeps and reveals, the placement of an object based sweep and reveal can either be horizontal or vertical. Let me start with a horizontal one, and I'm just gonna click somewhere on this wall. Notice then that you can actually keep going and pick additional walls. Now I'm gonna click the Modify tool to see the result of that, and let's zoom in a little bit closer, so we can see what that did.
Notice that the reveal is there, but it's actually carving away from the material on the wall. Let's do it again, and this time I'm gonna switch to vertical, and this time I'll pick the same wall, and it will place it in the vertical location. Notice that there's a Restart Reveal right here. If I click that, it places the first one and it lets me place a second one. Then finally I'll click modify to get out of there. Each time you wanna start over again, and place the Reveal in a new location, you can click the Restart Reveal.
Sweeps allow you to add material to the mass of your wall, and reveals carve material away from the mass of your wall. With both sweeps and reveals we can add them at the Type level, where they'll apply to all instances of that wall throughout your model, or we can add then wall-by-wall using the appropiate commands on the wall drop down.
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.
