Join Brian Myers for an in-depth discussion in this video Adding a structural floor to the project, part of Designing Home Plans with Revit.
- There are two different philosophies on how to do floors in Revit. One is to have a floor that's both structural and finish, so it would have your structural members on the underneath side of the floor, as well as any finish materials on top, such as carpet or tile. The other way to do Revit floors is to have two separate floors, one which is your structural floor, and then a second layer which is just the finish materials, such as carpet or wood or tile.
I'm an advocate of the second method because it makes it easier to change your finish materials as you're design develops. So, let's create two separate floors and we'll start by doing a structural floor. Underneath the Architecture tab, select on Floor, then under Properties, choose Floor, Wood Joist, 10". After choosing the Floor, Wood Joist, 10", zoom in, then select on the Pick Walls tool.
This allows us to pick walls inside of the project and then assign these walls as the outer boundaries for our floor. Make sure that "Extend into wall (to core)" is check-marked. If it's not checked, then you'll have difficulty doing this next step. So, with "Extend into wall (to core)" check-marked, zoom into the upper left hand corner of your building, then highlight over the walls. One of the things that you'll notice is this dashed line that shows up.
We actually don't want the dashed line to be on the interior side of our wall, we want that dash to be on the exterior side of the structural part of our wall. Now, we can't really see the dash because it's currently behind the line that I'm highlighting over, but this is the line that we need to select on, and this is part of the structural part of our wall core. So, we'll click at this location. We can see that it's drawn a line right along where this gray line is at. We zoom out.
We want to place another one of these at this location. We zoom back out. Zoom in, all this just by spinning the wheel of the mouse. Now we need to place another line along the outside structural for this wall, which happens to be in this location. So, click along this line. Zoom out. Zoom in over on the left hand side, pick this line.
Zoom out, and now we need to clean these lines up, so it forms one big rectangle around the perimeter of our building. To do that, we'll select on Trim/Extend to Corner. Click one of our lines, and click the other line to bring them together at an intersection. And continue to do this on each of the other corners so that we have one big rectangle going around the perimeter of our first floor.
Then, when you're done, click on the big green checkmark. It'll ask, "The floor and roof overlaps "the highlighted walls. "Would you like to join the geometry "and cut the overlapping volume out of the walls." The answer to this question should be yes, and what this means is that we'll cut material out of our walls, so that the walls themselves will be sitting on top of our structural members, or the floor. Also, because of the way that this is set up, and how we went to just the outside of the structural part of our walls, it means that anything on the outside of our walls, such as siding or brick, will continue to go down, and then sit on the foundation wall, or just on the outside of the foundation wall, the way that it's supposed to, and not get cut off along with the rest of the wall.
So, select on yes to that. And now, let's create a section through here, so that we can see what removing that material actually did. So, underneath the View tab on the ribbon, select Section. Click some spot here just outside of the building, and then click another spot, just inside of the building. Then, with this section highlighted, right-click, and select Go To View. Let's zoom in so that we can see where the floor and wall meet.
Right now, it's pretty hard to tell exactly what's going on, so to get a better view of that, we need to change our level of detail to a Fine level of detail. And here we can see that the wall is coming down, and it's actually sitting on top of the floor. Now, what would have happened down here, is we'd end up having a plate, so we'd have a couple of boards here that the rest of the floor would actually be sitting on. And that can all be detailed out in the wall section here. So, now we have the walls sitting on top the floor, and the floor would be sitting on top of the plate, which would then be sitting on top of the foundation walls, so it cut this part of the wall out, and that's what that question was asking us for.
If you click on the little "x" up here in the corner, in order to get out of this view, we can zoom back, see our floor plan view, and then if we select on the 3D View button, and then spin our view around by clicking on the upper corner of the View Cube, we can now see that structural floor installed inside of our house.
