Now that we have the profile ready to go and we've saved it back to our student folder, what we can do is we can load it into our project now.

Now that we have the profile ready to go and we've saved it back to our student folder, what we can do is we can load it into our project now. So I'll click 'Load into Project.' The profile has been loaded in.

I'm just going to jump back to my Default 3D view here. And we can now apply it to a mullion. So what I'll do is I'll select one of these mullions here that I'm going to change out.

You can see it does take a little bit of finesse to get to that. There we go. And that's me just cycling through with the Tab key until it hits the selection.

And it's helpful if you're on one of the edges here. And it's also helpful if you're not moving your mouse around a lot. So it's a Rectangular Two and a Half by Five.

We're going to do 'Edit Type' and 'Duplicate.' And we're going to call this one the Tapered Mullion. And we'll hit OK.

Now that we have a new type that we can work with, we can make a few changes here. So the big one that we're going to do is we're going to change the profile because we've created our own now. And so I'll change that profile to the Tapered Mullion.

You can see a lot of these things black out because we didn't make it parametric. We don't have the option to adjust the thickness or the width on side one or two. And that's OK because we made it specific to the size that we were looking for.

Once this is all set up, we can go and hit OK. And you can see we now have a Tapered Mullion in place of what was our regular rectangular mullion. So I can go through and I can use the 'Match Type' to apply it to these different elements here.

And now I have the Tapered Mullion going across at the top and I want to put it at the bottom as well. So I'll go ahead and select that one and hit CS for 'Create Similar.' I want to make sure this is set to 'Grid Line' so I can put it only on the horizontal ones.

And then you can see we've got the Door Header that needs to be changed out to the Tapered Mullion as well. And now we've got the Tapered Mullion assigned. Looks like we need to get the vertical mullion here.

So that's going to be our standard Rectangular Two and a Half by Five. So I'll select one of those using 'Create Similar.' Go ahead and add that one in.

And you can see after we've added the mullions, the vertical ones are still prominent. And so we want this to be continuous all the way across. So what we can do is if we select, say, one of these here, I have the option to make them continuous, which means it'll connect across both sides here.

Or it's hard to see, but there's a little toggle right in here, which is the same option to make continuous or not make continuous. If it's only one that needs to be adjusted, then the toggles work pretty well. But if it's the whole thing, you want to just hit 'Make Continuous.'

Now that only works for one piece at a time. And so if you wanted to streamline this a bit, you can go in and you can actually select one of them. And you can say 'Select All Instances.'

And since these are the only ones that we have in the project, you could say 'In Entire Project' and it'll select them all. And you can see we still have the option to 'Break, ' 'Join, ' or 'Make Continuous.' And if we hit 'Make Continuous, ' you can see we'll get a continuous run of the mullions going all the way across, which gives us this new look at the corners here with those being connected.

And now we have a curtain wall, pretty much the same as what we had before, but with a totally different look because we added the spandrel panel, the custom mullion, and the custom metal panels.
