Angled Mullion

Anonymous — Sun, 04 Nov 2007 03:17:10 GMT

Hello all,

I'm using Revit to create curtain walls, I would like vertical/horizontal and ANGLED mullions in the wall. I understand how to create vert./horz. but don't know where to start with the angled ones. Can anyone help?

Thanks

No that difficult. The actual Curtain wall element properties (Instant) provide parameters for angling the grid-lines/mullions. Select the Curtain Wall and in the Elements Properites dialog box under the Vertical Grid Patterns and Horizontal Grid Patterns groups select the Angle parameters to change the angle the grids are in the wall. This angles the entire grid, vertical or horizontal, pattern.

You can also angle the mullions about their Grid-line by selecting the mullion, vertical or horizontal, and in the Element Properties dialog box under the Constraints group, select Angle parameter and change the value. If the Curtain wall used is the Exterior Glazing or Store Front or a Type you setup with the properties for the vertical and horizontal grid and/or mullion patterns preset, then you will have to Unpin the grids and mullions before you can make any changes to the curtain wall or mullions, such as changing one or the others angles.

I should add that you cannot create in-place curtain walls, since there is not category under the create in-place tool for curtain walls. You could create in-place a curtain wall using the Wall category but it will behave like a Basic wall type not a Curtain wall type. So mullion profiles and panels cannto be assigned.

How about a simple angled mullion amongst regular horizontal and vertical ones - this in elevation, not in section?

Thanks,

You would need to create a panel family with a diagonal "mullion" in it in order to get this appearance.

I am trying to replicate the condition on the left in the attached photo.

I understand how to angle the horizontal and vertical grid lines.

The issue I am facing is that I am trying to angle only the top border and top mullion (as pictured), but to no avail.

Any assistance would be greatly appreciated.

See Revit 2017 file attached. Ask if you need explanations.

Toan your file does nothing to help me understand.

I would have resorted to a mass with intersecting lines by now.

Curtain system over mass with intersecting grid works too. I just wanted to show the approach of using regular curtain walls.

Ah I get it now. But how can you change the uppermost border mullion?

Re: Angled Mullion

Edit the main curtain wall profile, or attached to a roof/ floor/ ref plane.

@chrisplyler

And I need to clarify that this method is for when you need a just few off-the-rule grids like the one @pcfarnan13 shows in his photo. If the entire grid needs to be flexible, then creating a curtain system based on a divided surfaces using intersecting reference planes as you suggested is the way to go.

By the way, below is an example of changing a curtain wall top by attaching it to a ref plane.

AHA! A reference plane. I'll smack myself across the forehead now.

Hi and thank you for helping out on this.

I have a question. On step "2" where you say to Use Another Curtain Wall type as Panels. I am not understanding how or what to select and switch over? Can you please provide some more detail on that?

Thank you,

Look, I think I got it and since I was in the same boat as you when searching for this issue, am going to explain it to you cause the explanation here is a little vague. The main point that you should keep in mind is that you are going to work with the panel of your original curtain wall. Just select a panel in you curtain wall and unlock it. Now you are going to change this panel. In the list of the panel you can see that you can select a curtain wall, select it. And this is the way that you are going to work, with a curtain wall inside a curtain wall. Now you can change the angle of the mullions of the curtain wall inside your original curtain wall.

I hope this will help you.

Hi! This might be a repeat question, but I kinda got lost by what you meant by "Just select a panel in you curtain wall and unlock it", how do I select? by Tabbing on the Main Curtain wall?

Hi! This might be a dumb question, but How do you nest a Curtain wall into an existing one?
