And then what we could do is we could select it, and what I like to do here is I can go in and I can actually use the sunglasses setting here, and I could say isolate element, and that'll isolate just our curtain grid and curtain panels here that we had that were hosted on that wall. And then we can go in and we can add the different mullion types that we want to use for this. And so what we'll do is I'll start by adding mullions to the whole thing here, just with that two and a half by five, and then we could decide how we want to address the rest of these.

And so if we go in, we could say that we want the verticals different from the horizontals, or we could have it where they're just all the same. And so in this case, we can go ahead and we can add a different type for our vertical and our perimeter than we have on our horizontal ones here. And so one of the ways that makes it easy to change out mullions on the horizontal is you can right-click on these and you can actually select the mullions along your grid line.

And so if you have your grid line selected, like I do here, then I could right-click and I can actually select the mullions that I want. If you have the mullion selected here, then I can select the mullion and I can right-click, select mullions on grid line, and it'll select all the mullions across the grid line there. And then I can change this one to, let's say the one and a half by two and a half rectangular.

It gives me a smaller one, just a different profile look. And I could do that across the board here. You could also do this in elevation, but then remember before when we went and did that, we ended up selecting a lot of things that were in the background.

So it's a tricky game to play there with adding those. And so you want to make sure that you're not selecting elements and changing them out that you don't want to change. Okay.


So there's definitely other ways you can go about this if you wanted to just pick them, but I think this is going to be the most efficient method here. So another option that we have here is I can go in and I can select one of my mullions here. I could right-click and I can say select mullions, and then I can say on horizontal grid, and that'll select all of the horizontal mullions.

And then I can go ahead and I can change those to that type. And that takes care of it for the entire wall, which I'm sure everybody appreciates. And then I can go in and I can say, well, let's make this one a little different.

So I'll say edit type and duplicate. And I want to make this one a little deeper. We'll call this one the two and a half by eight rectangular.

And because we made this an eight inch thickness here, I'll go ahead and make that eight. And if I want the relationship to be the same, I need to change my offset. So I'll make that three inches.


Because that will give me the same overall location for where my glass hits the mullion. So I'll hit OK here. And then I can do the same thing we did before where we changed these mullions.

So I could say right-click, select mullions on vertical grid, and I can change all the verticals to that new two and a half by eight type. And then I can do the exact same thing one more time, select mullions, and then I can say border mullions, and it'll select all the perimeters. And then I'll change those to two and a half by eight.

And that is probably the most efficient way you can create a wall with this much variation within it. Once you're done there, you're going to want to go ahead and reset your Temporary Hide/Isolate so you can see your building again. And then you definitely, without a doubt, want to go ahead and save so you don't have to go through that again.
