Designing curtain wall corners requires multiple steps, including unpinning and deleting mullions, choosing the mullion type, placing it at the right angle, and adjusting its position for a neat finish. Sometimes, you may face difficulties when the mullions are not joined where they should be, or if you find that the mullion doesn't sit perfectly on the corner; this is when you must push Revit to achieve the desired outcome.
Key Insights
- The process of creating curtain wall corners involves unpinning and deleting the existing mullions. This can be done by selecting the corner and unpinning the mullions.
- After deleting the mullions, you have to select the desired mullion type from the architecture tab and place it at the right angle. This may require multiple attempts as the mullions often don't join where they are supposed to.
- At times, you may have to coerce Revit into generating the desired outcome. This could involve over-drawing a mullion and then trimming it back, or adjusting its position until it sits perfectly on the corner.

To create the curtain wall corner condition that we're looking for, what we'll need to first do is delete these corner mullions that are shown in right now, and they're actually just our standard two and a half by five. But before we make that type of a move, we'll need to unpin them. And so you can see where I've gone through and actually done a window to selectively just grab that corner.
And that allows me to only grab those two pieces. And then I can easily unpin them, delete them. And then I can go in from my architecture tab, go to mullion, pick my five by five quad corner that I want to use here, and then place it in.
And we've got to get in the right angle here for that. And what I'm seeing happening here now is they're actually not joined where they need to be. And so this is a common thing with curtain wall.
So again, I'll trim extend the corner, make sure everything works out there. And then I can go back in and try and place the mullion. And if that doesn't work, you can see I'm getting kind of the, now I'm getting the dashed line here.
You can see what's happening is they're not quite on the corner here. And so what I'll do is I'll go back into plan view and I'll take one of them and I'll draw it out further than it needs to be so that they cross. And then I'll use the trim extend the corner again.
And now you can see the corner is much more appropriate for that mullion. And I'll go back in and add that quad corner. And now we get the condition that we're looking for.
And so we'll check it out in 3D. And it looks exactly like what we want here. This is a common thing that'll happen when you're doing that.
And so sometimes you, you almost have to force Revit into doing what you want, which essentially means just over drawing something and then trimming it back most of the time. So you can see here, this one, when I deleted it, it gave me a much better condition because you can see that those two walls are right next to each other. When I go to place the mullion, it works pretty, pretty simply.
So I'm just going to track this all the way around the building here. Um, except for this one, that one's going to change a little bit. We don't want to mess with it too much right now.
And I'm going to go through and do the same thing. I'm just going to add those corner mullions. And you can see here, as I go through, I need to make sure that I'm not grabbing the wrong elements.
And one thing I just noticed is that this wall is actually not at the right settings, so it should have a negative four foot offset. So it's kind of good that we picked up on that. Let's see.
This one might be the same. Nope. That one's good.
And so that's something you'll want to be checking too, as you go through. And so I can go through, unpin, delete, and then just add the mullion in. You could also do this in your plan view as well.
So there's no reason, because there's just one, one mullion. So you could easily do this in plan view, where I can delete that. And then I can add my mullion.
Might be easier that way. Certainly easier to select things. And we got one more right here.
So I'll go ahead, unpin, delete, and then add that corner mullion. And let's just double check to make sure we got them all. And again, except for these ones, because those are going to change here.
We'll save those for later. And it looks good. So I'm going to go ahead and save, because I haven't done that on screen in a while.
But it's a good thing to make sure you're jumping in and saving pretty often here.
