Explore the complexities of modeling and adjusting the elevator core in Revit Structure. Learn how to modify structural walls, footings, and foundations to accommodate an elevator pit and ensure constructability.
Key Insights
- The tutorial focuses on adjusting the elevator pit, which is located five feet below the finish floor. This requires moving the footings down to ensure the constructability of the pit.
- Detailed steps are provided on adjusting the parameters of columns and walls, which are attached to the footings and foundations. These changes allow the foundations to be at the same elevation as the elevator pit.
- The final part of the tutorial demonstrates how to adjust a perpendicular wall and its attached foundation, thereby ensuring that its elevation matches the rest of the elevator pit. It also provides a 3D view to visualize the modifications made in the structure.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Hello, and welcome back to Revit Structure. Let's get started. In our previous video, we had finished modeling the equipment room and placed openings in our structural walls that had been provided for us by the Architects Relinked model.
We have one other area we need to look at before we finish this basement. That is the elevator core. Let's zoom in on it and take a look at it.
At the elevator core, we have a pit, which is five feet below finish floor. Well, what we need to do is we need to bring these footings down for constructability of this pit. Okay, let's get started.
Let's cut a section. We're going to cut a live section, save the project. Let's cut a live section from this grid line to this grid line.
And we find this in the View tab under Section. Let's modify this section to accommodate our needs. Okay, let's pick it.

Let's flip it with the right-left arrow. Let's move it back so we can encompass the area that we need to work with. Stretch it out so we can see all of our elements.
Let's pick it twice, and there you have it. Okay, what we're going to do is we're going to compress this window so that we're looking basically at the area we need to work with. Let's bring it up to a scale we can work with.
And let's change its visibility to Fine. Let's zoom all, ZA, and there we have it. We don't need the architectural background, so let's type in VB.
Let's go to the Revit Link tab, and let's turn off the visibility by unchecking it. Let's hit OK, and there we have it. The first thing we want to do is we want to get this foundation to the same elevation as this, and this elevation to that same elevation.
Okay, let's start by picking a column and checking its parameters. Because this foundation is attached to the bottom of this column, when we change the column, it'll change the footing. Our base level offset is at minus one.
We want it at minus five to match the elevator pit, so let's put in minus five. And we get a dialog box telling us that an attached structural foundation will be moved to the bottom of the column. That's correct.
Let's hit OK. Here we have it. The column foundation is now flush with the top of the pad.
Now, we want to get this foundation to that same elevation. Well, this foundation is attached to our wall, so let's tab until we find our wall. There it is.
Let's pick it. Okay, what we want to do is we want to edit the profile, so we'll go to the contextual tab. We'll go to the mode panel, and we'll go to the edit file tool.
Let's pick that. We see now that our wall is in purple, as we have done previously with floors, we can do with walls. Okay, let's create our wall.
Let's pick line to the top of the footing, and let's draw a line from the end of that line up to, up two feet, over to the grade beam, and then up. Okay, what we're going to do is we're going to trim this wall here to here. Trim this wall from here to here.
What that will do is it will create the footing to follow along our wall line, since it is attached. Let's go to our contextual tab here under mode. Let's check it, because that's what we want.
Okay, there we have it. We have a step slab down to the top of our elevator pit slab. Now, we want to do the same with this one.
So again, let's tab until we find our wall. There we have it. Let's again go to our contextual tab, our mode panel, edit profile.
This one will be a little easier, because what we want to do is we want to just bring it to this point and this point. Now, let's trim here, here, here, here, here, and here. Well, we have restrictions on this, so we need to create an offset, because we can only go two to one.
So let's draw a line from this point, four feet, up two feet. Okay, let's trim those lines up, because we have to have a closed loop here, here, here, and here. Now, what will happen is since our foundation is attached to our wall, it will follow the line of our wall.
Let's again go up to our contextual tab, our mode panel, and click the finish to edit mode. Okay, there we have it. We have the foundation set with steps to match our wall.
Okay, we have a wall here that is perpendicular. Let's go back to our plan. Let's rotate this.
Let's pick it, pick the rotate command in the modify panel. Okay, let's turn it and give it a degree of 90. There we have it.
Now, let's put it in position, so we can see what we're dealing with here. Let's pick it twice, and here we see we have our small wall, our small intersecting wall, here. Okay, with this one, it's a little simpler, because we need to go down the five feet, and we can just reset the base of our wall to minus five.
And with that foundation attached to it, it will automatically reset that elevation of that footing to minus five feet. Okay, let's go to our 3D and take a look at it. Let's go to our project browser.
Under 3D views, let's pick 3D twice. Let's take a look at that foundation. Okay, let's zoom in here.
And we can hold down the shift key and the scroll button and rotate this. As you can see, we have our walls and our footing stepped down to our elevator pit. Very good.
Let's get out of this. Let's close our section out. Let's delete it.
We're done with it. Is it okay? Let's zoom out. Zoom all.
And that's it for this video. See you in the next one.
