Join Paul F. Aubin for an in-depth discussion in this video Understanding sweeps and reveals, part of Revit: Rendering.
- In this movie we're gonna continue looking at customizing our wall types and we're gonna look at wall sweeps. Now, we're gonna look at two examples of how to create wall sweeps. One is at the type level so it will apply to all instances of a particular wall type and the other is wall by wall or at the instance level. Now, when we built the wall type initially, we worked over here on a wall off to the side and you could continue doing that with the wall sweeps but I think in this case, I'm gonna actually delete that and work directly on the walls themselves. So I'm gonna zoom in slightly and orbit the view to get a slightly better look and then select this wall to get started.
So I've got the wall selected and I'll go to edit type. Now as we discussed in the previous movie when we added the stucco to the wall, in order to edit the structure and work on the vertical structure, we need to expand the preview, and then make sure that it's in a section preview in order for these buttons to become available. I'm also going to zoom in here at the bottom just by rolling my wheel. Because we're gonna be working down here at the bottom of the wall, and I want to be able to get a better look at that.
And then I will click the sweeps button here which will display the wall sweeps dialog and now I can begin adding sweeps to this wall. Now, sweeps are based on profiles. A profile is a 2D family that just creates an outline, and then that outline shape is actually swept along the length of the wall. That's why they call it a sweep so it actually extruded along the wall's length and becomes a 3D solid. So, if I click add here, it will add a profile or a sweep to this wall.
The best way to see what that did is to click the apply button and then watch the preview window in the background. And notice that we've got this little square shape that's now been added to the wall. Now, the reason it was added down here at the base of the wall is because this from setting here can either be measured from the base or top. So we're gonna leave it at the base. This distance here measures from that setting. So, if you do a positive number it will actually move it up, and a negative number would move it down. But I'm gonna reset it back to zero.
You can assign it to either the exterior or interior of the wall. And in this case, I'm creating a masonry band so the exterior is appropriate. The offset setting is within the thickness of the wall so if you want to move it outside the phase of the wall or within the thickness of the wall, you can use either positive or negative numbers here. So notice that a positive number would shift it away from the wall and a negative number would move it within the wall. Now, I've got brick material here.
It's currently 3 5/8 inches in thickness. So what I'm gonna do is make the offset equal to that and because I'm going within the wall, I need to use a negative number. So I'm gonna do -3 5/8 inches to kind of shift that within the thickness of the wall. Now, I don't want this simple square here. So I actually want to use a different profile. If you open up the list, there's a whole bunch of profile families already loaded into this project file.
Now, if you want a profile that's not on this list, you can click the load profile button down here and browse out to the hard drive to find another one. But I'm going to use one that is on the list here. The Wall Sweep CMU Course 6 Blocks so that's gonna create a tall sweep that's actually six concrete blocks tall, and I'll click apply and you'll see that will change the shape of that simple square to reflect the shape of six concrete blocks stacked on top of one another. Finally, over here on the right side, I want to check this box to make this sweep cuttable.
In other words, if I put a door or a window within this wall I want it to be able to cut through this horizontal band that I'm creating at the bottom. You can assign it a material so I'll click the browse button there for material. Up here at the top, I'll type CMU to search for all of my concrete masonry unit materials, and I've got one here concrete masonry units split face which seems like a good choice and I'll click okay. Let's okay again. You'll see it preview here in the window, complete with its material.
Notice that it is cutting the brick and removing that layer of brick beneath it. I'll click okay one more time and then again, and it will now apply it throughout the model. Because I did edit type, it applies it everywhere across all instances of this wall type within the model. Now that's a very effective way to add a wall sweep when you want the same condition everywhere on all instances of the wall. But in some cases you just want to add sweeps to particular walls, and rather than having to edit type duplicate and make lots of different copies of the wall, you have another option here where you can actually add the sweep wall by wall instead.
So when I choose this option, wall sweep, over here on the properties palette I'll be able to choose from the different sweep types that I have available. Now there's two already in the project. I'll use the wall sweep trim which is just a simple trim board and the way that this works is you highlight the wall that you want to add it to and when it's at the height where you want it to be placed, you click to add that first wall. Now, notice that if I turn the corner and add the next wall, it will match the same height.
And more importantly, it will actually create a single continuous sweep that includes all three of those walls. Now at anytime I can click this button here to restart the sweep over again and it will finish the one that I was working on and allow me to add a second one. Now notice that if you click where there happens to be doors and windows penetrating your wall, the sweep will actually start and stop at each opening. So it's being interrupted by those inserts which is another handy feature.
So I'll go ahead and place a couple more trim boards there and then I'll restart again. Now another feature that we have here on the ribbon is to change the orientation of the sweep. So it doesn't have to be horizontal, we can make it vertical, and then you can click on any wall that you want to place it on and create that vertical sweep. Now I'm gonna click the restart button one more time and you can actually go over to the properties palette. Use your edit type button here and using a similar technique to what we just discussed with the wall type, you can actually duplicate and create custom sweep types, so let's do that now.
So I'm gonna click duplicate here and I'm gonna call this one Precast Cap and I'll click okay. Now I'm gonna configure a few settings. I do want it to cut the wall, I do want it to also be cut by inserts. So same as we saw here where the windows will be able to cut around it. It doesn't need a setback that would actually occur at the windows. It could actually set it back from the window opening but I'm gonna leave that at zero. What profile do I want to use? Well, I'm gonna open up this drop down list here and choose a different profile this time.
This one called Seal Cap 4" High. Now I created this family. It's pretty easy to do. It's just a simple outline to represent the shape of that profile. If you want to learn more about creating profile families we do have movies on that in the family editor course here at lynda.com. So you're welcome to jump over there and take a look. Let's give this a material and in this case I said I wanted it to be precast. So let me type precast here at the top and it will display all my concrete materials.
I'll select a concrete precast right there, click okay. And this is probably my favorite settings of all in these individual sweeps here. Sub category of walls. If we open up this list, there's a few choices but I'm gonna leave that on Wall Sweeps Trim. And what's gonna happen is that the wall sweep will actually get a different category than the wall itself. So I'll show you that in just a moment but meanwhile let me go ahead and change the orientation here back to horizontal.
And then place one there maybe and right there and perhaps right here as well. And then let's go ahead and cancel out of there. Now I'm gonna zoom in and show you the result. So, that was a little chamfered shape there. You can see it really clearly right here this little chamfered shape that represents the precast cap. Now, let's talk about that sub category of walls. Why is this important? We talked about different kinds of models in an earlier movie designing tent models versus rending models.
Well, sometimes when you start adding all of these details to your modeling for rendering, the folks working on the model for construction documents or for other purposes may not want to see all of these extra detail. Well, the really nice thing about the sub category of walls feature is I can go to visibility graphics, VG shortcut, scroll down and locate the walls category, and notice that Wall Sweeps Trim is a sub category of walls and I can turn it off.
And when I click okay, that wall sweep is gonna disappear. So I've just simplified what's being displayed here in this view. So now just the folks who are doing the rendering can go to VG and turn on that wall sweep when they want to see it for rendering and everyone else can turn it off if they don't need to see it. So that's why I'm really fond of that feature. So, wall sweeps can be added directly to the wall type if that's appropriate but you cal also add them individually wall by wall.
And so, however you add them there are way to add a lot of details to the model in a very quick and efficient way to represent anything like moldings or stone bands or any of those little details that really start to make the wall come alive and make it a more interesting overall design, and certainly to make your renderings pop and read better.
