Curtain wall butt glazing

[halearchitects]

I thought I read somewhere that a new feature in 7.0 would allow glass to butt in corners without a mullion. how is this done?

Also horizontal mullions are supposed to join better at non 90 degree corners in 7.0 and this appears to be correct but, I seem to be having a problem with the top mullions which are not joining. Any ideas what would be causing this problem. Both walls have the same height settings.

I've always had to make a special panel family for corner conditions in SSG glazing, I don't know if 7.0 has a built in way to do this. But creating the special panel is very easy, just add an extension parameter to oneside of the panel family and reallign the panel to it.

When you select a mullion in elevation view, Revit displays a control at mullion intersections to select which mullion runs continuously at that intersection. Try to change this at the intersection that causes the problem. This happens often at corners.

Scott,
Thanks for the reply but I am not sure I follow what you are trying to say regarding creating an extension and aligning it.

Carlos,
regarding your suggestion about the intersection toggle. I do not get a toggle for that end of the mullion since there is no vertical mullion there.

Any other suggestions to get the horizontal mullions to join would be appreciated.

Thanks

Here is a possible work around.

I created a new corner mullion based on the Quad Corner Mullion. I set depth 1 & 2 to 1" (matching the depth of the glass). Offset is 1.25" (to match the typical glass offset). Finally I set the Material to Glass.

While this is not a true butt glaze it does come pretty close to the effect.

Here is a copy of the file to show how it works. I'd be interested to see how others have worked around this as it's a detail I like to use.

Oh, and file's in 7.0

Good Luck,

here is my corner panel family.

Just downloaded and used the ssg panel corner. Thank you. Thank you, Thank you. It solves so many problems.

You are very welcome.

This solution to an old question came out of the blue this evening. Example project and image attached.

All the best -

Now speaking of butt-glazed curtain walls, most SSG systems have a corner mullion situated at a 45-deg. angle (on curtain walls that turn a 90-deg. angle) and the glass comes up on each side in front of that 45-deg. mullion. Is there no way to create a mullion like that, or any kind of 45-deg. corner mullion, either regular or butt-glazed, in Revit? I couldn't figure out how to make one.

I use a column family for the corners.

Is there no way to create a mullion like that, or any kind of 45-deg. corner mullion, either regular or butt-glazed, in Revit? I couldn't figure out how to make one.The attached image is all the system corner mullion families based on their stock size when applied to a 45 degree intersection. I admit I don't really follow your question, but does these profiles in context start to deliver what you want if you alter the dimensions of them?

[patricks]

I'm talking about this, a SSG corner mullion. The profile shape has 6 sides total:

Thats the exact one I have used in previous projects, just make a column family or generic model and embed the detail component in it. I also make corner panels of glass that do what they need to do. I will try to dig up my project and send you the pieces.

[patricks]

I assume you just made a regular column family, not a structural column?

Hey there,
I have also used an in-place extrusion to mimic the standard corner mullion frame from the Vista Wall details.

Good luck

I'd like to revive this discussion.

First Question. Is there a better solution for this in 2010?

If not. Read on.

I've downloaded the files from this thread but I'm left unclear on exatly how this should be done.

One family is standard curtain wall panel with an offset parameter. It seems like this is not a perfect solution because the curtain walls have to overrun each other to get the horizontal mullions to look right in 3d. This doesn't look right in plan.

Another family is a "wall" embedded as a panel, where the "wall" is the IGU. From this file I was left lost as to how I would create or modify this. The mullion type and glass offset for example.

I know I can count on the experts of this community to point me in the right direction.

Thanks,
Mark.

Steve's (Stafford, that is) got a post on his blog about another way to accomplish this.

first off to everyone , thanks for the helpful comments and files. One questions I do have, as a new revit user I d/l and opened the Butt-Glazed curtain wall.rvt file.
I don't truly understand why when I tried to replicate the curtain wall in that file I cant. the panels didn't butt properly. its probably something stupid that I didn't do properly. does it have something to do with the witness line??? any help would be appreciated.
thank you.
