Learn the step-by-step process of utilizing Revit Structure to complete the placement of slabs in a building structure, with a particular focus on the equipment room. The guide also delves into adjusting wall heights and placing structural slabs.
Key Insights
- The article provides a thorough guide on using Revit Structure to complete the placement of slabs, emphasizing the method of splitting boundaries and trimming lines to create a continuous loop for the slab.
- The guide highlights how to adjust wall heights in Revit Structure, using the example of an equipment room where the wall height had to be readjusted to match the underside of an architectural slab.
- The process of placing a structural slab is also detailed in the article, including selecting the appropriate slab and setting the height offset based on architectural specifications.

Hello and welcome back to the Revit Structure video series. Now that we've put the openings in our equipment room and the front of our structure, let's finish putting in slabs. Okay, let's go to the equipment room and let's finish out the slab.
Okay, so let's tab until we find the floor slab, which is there. Pick it. What we're going to do is we're now going to go to the Modify | Floors tab.
It's a contextual tab. It comes up when we pick the floors. So let's go to Edit Boundary, pick it, and here we have the boundary highlighted in purple.
Okay, let's go ahead and split that boundary. That way we can work with it in a moment. Let's go to pick lines and start picking the locations of the slab that we want to have for our new equipment room.
Let's start here. Let's go here, here, here, and here. Okay, what we want to do is, since we have a contiguous line here, let's split that one also.

Let's pick that here, and we have one more line to pick right there. Okay, now we can go to the Modify panel, to the Trim/Extend to Corner command. You see the TR there.
That's a shortcut. You can type in TR and have the same command come up. So let's pick it and start trimming our lines.
Let's pick here and here, here and here, here and here, and on and on until we have one continuous loop for this slab. Let's hit okay. Okay, and there you see we have our new slab in our equipment room.
Now that that slab is set, let's cut a section through the vault, take a look at what we need to finish up for the top slab cap of our equipment room. Let's pick that. Let's adjust it.
Let's pick our section. Okay, again, let's adjust our section. Let's make it a workable size, zoom all, ZA.
Let's make it a workable scale. Again, I like quarter inch. And let's go to a fine look on this, and let's go to VG, which is our Visibility/Graphics Overrides.
Go to our Revit Links, pick that, half tone it, make it a background. Go to our host view, custom. The detail level is already fine.
So let's go to the discipline here, make it architectural. Is it okay? Okay, again. There we have the architectural background.
Oh, we noticed that the architect's model has the top of that wall actually lower than the original eight feet that we had anticipated. Okay, let's go ahead and fix that. Let's take a measurement in the Modify panel > Measure Between Two References because we don't want to place a dimension, we just want a measurement. Let's pick that. Let's go from our finished floor to the underside of the slab.
It's seven feet, three inches. Okay, let's escape out of that, go to modify. Let's close this tab.
Okay, so what we want to do is we want to readjust our wall height. So let's pick the walls at the equipment room and it's seven feet three. Now remember we're one foot down to the base offset and our unconnected height is the total height of the wall.
So what we want to do is we want to make this wall eight feet three. Okay, now that we've completed that, let's take a look at our section again. Okay, our wall now matches the underside of the architectural slab.
Now we want to place our structural slab here. So let's close this and in this foundation plan, we won't see that slab actually being drawn and we will fix that in a moment. But we do want to draw it here because we want the underside of that slab to be referenced from elevation zero or the basement level.
Okay, let's go to structure. Let's go to floors because that'll give us the slab that we require. Let's pick that.
And here we see we have a 5" Concrete Slab. Well, it's carrying some load from the earth above. So let's take a look at what we have that's thicker.
We have a 6" Concrete Slab, but let's use our 9" Concrete Two-Way Slab that we used at the level to be consistent. Okay, let's pick that. Now we have level zero and a height offset from our level, which is level zero, should be seven feet three because that's what the architect has specified for his clear height.
So let's pick that. Okay, 9" Concrete Two-Way Slab. Now, again, I like using pick lines, so you can use what you're accustomed to.
Actually, easier would be drawing a rectangle. So let's go there. Okay, we have a rectangle picked, so we'll pick our far corner and we'll drag it down to our lower corner here, the intersection of that wall, place it.
Okay, you can see we have an outline, which is a boundary line for our slab above. And again, you see the three lines here, that designates our span direction. And we want our slab to span in the short direction.
We will go up to the modify, create floor boundary, which again is a contextual tab. And we'll go to the mode and finish edit mode. And we'll pick that.
And our slab is in place. Let's look at that in our 3D model. Again, let's go to our Project Browser, 3D view, pick it twice.
Let's take a look at what we have. Let's swing around to the back of the building. Let's zoom in.
And there you have your slab, which looks like it's embedded in the wall because the top of the slab is at the same elevation as the top of the wall. So let's get out of this and make an adjustment. Let's pick our section.
Let's go here. And since it gave our floor line, the top of wall, let's adjust it up nine inches. So from seven feet three, we'll adjust that to eight feet.
And there you have it. Our cap slab is in place, our walls are in place, our floor is in place and the foundations. So let's get out of this detail.
Let's get rid of the section, delete it. Let's take a look at our 3D model again. Let's zoom in.
And there you have it. You have your new equipment room. And then to front, we have our opening for the new basement access.
Let's zoom all. Let's close this. Let's zoom all of our basement.
And that's it for this video. See you in the next one.
