Discover the process of creating levels in elevation views, and adjusting them based on building extents. Learn about adjusting grids and creating new levels such as the roof and top of parapet for a more accurate model representation.
Key Insights
- Levels in elevation views are created according to building extents and can be adjusted for precision. The adjustment involves moving the 3D extents of the levels out and aligning them closer to the relevant grid line.
- Additional levels such as roof and top of parapet can be created based on the specifications provided. These levels can be created either by copying an existing level or through the architecture tab.
- Ensuring the accuracy of level placements involves checking from different elevation views and making necessary adjustments. It's also essential to rename the levels and corresponding views accurately for easier identification and management.

To create our levels, we just need to go to one of our elevation views, and so I'll just go to the South view, and we can take a look at what's already been created, and I can see here I've got Level One and Level Two, but it's important to note that, you know, our building extents are going to be between these grids here, and so you can see the levels have been set up for just a default, essentially having the center in the actual center, not on a corner of the building, and so we'll make an adjustment here by moving the 3D extents of the levels out, and then we'll tighten it up a bit by moving it a little closer to this grid line one, because that's exactly where we're going to want it going forward. When I look at my levels and their definitions, you can see I've got Level One and Level Two, but I've also got a Roof and a Top of Parapet I need to create based upon the PDF that's been provided. We have our existing being 0,14,25, and 28, and so we'll use that as our guide to create the other levels.
So Level Two, instead of 10 feet, I want that to be 14 feet, and you can see really quickly that these grids are not going to be sufficient, so I'm going to move them up so that they're closer to where they're going to be in the long run, keeping in mind that this is only moving grids one through four. We still have the A, B, and C, or the A and B ones that we have to adjust. So the next one is going to be creating our level for Roof and Top of Parapet, and we can do that a couple of ways.
If you remember from BIM 101, we can take this level and copy it up, or we can go to our 'Architecture' tab, 'Levels, ' and create it that way. I like this one because it gives me the option to have the view right away. I can always have it not create a plan view if I didn't want to, but it's something that's not really a bad thing to do.
So I'll go ahead and just use the extents, not worrying too much about the height right now, and I'll adjust that. And the height for this one is going to be our Roof level, and that's going to be at 25 feet. So I'll change this value to 25, and I'll go ahead and rename it to Roof.
It's going to ask if you want to rename the corresponding views. This is a yes almost all the time, so we'll say yes here. And then we can go ahead and we can copy this one up just to use both of our methods that we know of.

We'll go ahead and copy it up vertically, and you can see I'm not really worried about the dimension here because I know we're going to go back and change it anyway. So I can change this to 28 feet, and we're going to call this one Top of Parapet. And there we go.
We've got our framework set up for our model, and so I'm going to just make a couple adjustments. We'll probably adjust those later, but I also want to go to one of my East elevations and make sure that everything looks good for this side of the building. And you can see A, B, and C are a little weird, so we're going to move those up, and we're going to bring in the levels across on the tail there.
And everything looks good. So I'm going to go ahead and save, and we're going to pick up right where we left off in the next lesson, and we're going to be diving in with the creation of the existing building.
