Fastest way to reduce the width of a curtain wall system

[gnarkill283]

This program never ceases to frustrate me. I have a curtain wall that I need to reduce in width. When I go to the reduce width of the curtain wall, instead of quickly eliminating all components revit drags them into my remaining curtain wall creating a giant mess (who would ever want THIS?!). I've tried deleting all mullions and doors before the reduction but revit still pulls grid lines over and there seems to be no way of deleting these. Please tell me there is a simple solution to this because this should have taken me all of 2 sec to do. Thanks.

It depends on your curtain grid configuration.  If they are set at a fixed distance then reducing the length of the curtain wall will eliminate the grids outside of the new boundary.  If they are manually placed and perhaps, set to equally spaced, then reducing the length of the curtain wall will compress those grids to fit equally within the new boundary.

Look at it from a different perspective.  If someone has spent a lot of time laying out the grids and placing different types of panels.  Now he wants to reduce a length from 100' to 99 ', and everything go poof...

So for your case, here's how you do it:  Reduce the length of the curtain wall, do a window selection around the curtain wall, filter to keep only the curtain grids, then delete.  All the grids of that curtain wall will deleted and so will panels and interior mullions.  Another way is temporarily changing it to another type with the divisions set to Fixed Number, then change the Division number to 1 and all interior grids will be deleted.

Are you talking about grid lines/mullions that you added to the original configuration? If so, you need to constrain them. You shouldn't be needing to delete doors, mullions, etc.

Hi

Just telling the workaround which may help you..

change that curtain wall to some other wall ( non-curtain wall ),

this will delete all the gridlines etc which you might have added manually..

and then convert it back to the Curtain wall ( the type you need )

Just be-aware that this process will delete all the doors, custom grids you made for that wall..

( to experiment this, you can copy that wall bit away from the building, try the above procedure and if you

are getting what you are looking for then just do it... )

Cheers !

do not reduce the width, but edit the profile of the wall instead.

Thanks for your reply ToanDN but you start the solution by saying reduce the length of the curtain wall - when I do this everything becomes a mess and I can't filter out the mullions I need vs the ones I don't. You also mention filtering the curtain wall grids and deleting them. I can't. It says "Cannot delete or group a type driven gridline without doing the same to its host." Even if I select one individual curtain wall grid with all the mullions deleted, nothing happens when I hit delete over and over again. As for this: "Another way is temporarily changing it to another type with the divisions set to Fixed Number, then change the Division number to 1 and all interior grids will be deleted." What other type? And how do you make a curtain wall by fixed distance vs manually placed?

[gnarkill283]

Your solution to reducing a curtain wall width that I spent hours working on is to delete all the customization? Yea thats not going to work for me.

[gnarkill283]

Yep I tried that from the beginning. Creates another mess. I get the following errors: "Type associated curtain grid lines outside of the edited wall boundaries will be made dependent again in order that they remain on the wall." Then it forces me to make line dependent. Then this error: "Manually placed curtain grid lines are on the wall edges or outside the wall boundaries." Then it forces me to delete elements. Yet it still mushes everything over.

deleted to save face 

...Okay, let's try again: What about Splitting the CW and deleting the portion you don't want? No? 

[FAIR59]

I made a test wall, [ vertical grid layout fixed number ] and I works ok (except the new border panels), even after deleting associated curtain grid lines outside of the edited wall.

( Revit 2016). The coloured parts are manually placed.

What are the type-properties of your curtain wall?

What "works ok"?

See my attached image for my ****ty solution to what should be a very straightforward procedure. I just smooshed all the curtain wall grids to the side. Strangely sometimes if I placed a grid over another one it would tell me they were overlapping and I could delete but again this was completely random behavior. This should've taken me 2 sec to do but instead I had to come here and bother you guys and spend another 2 hours troubleshooting...

[gnarkill283]

tried couldn't split or trim. Split with gap ****ed up all the grids and deletes things.

[gnarkill283]

You're speaking Chinese to me. See my attached image in previous post for screenshot of properties.

[gnarkill283]

ToanDN,

I made a curtain wall by clicking on wall, then storefront, and then drawing the extents of the curtain wall within a wall. Is that a fixed distance based curtain wall? Because it still does that same thing. look at attachments. I don't know how else to make a curtain wall.

@gnarkill283

I have no idea why you can't split and delete.  

I also don't get you are unable to apply a locked constraint to the added grid lines to control their location. 

Very curious.

@gnarkill283

looking at your screenshots, I'm wondering how Revit knows what to do with those added grid lines when the wall is stretched? 

[gnarkill283 · Accepted solution]

I FOUND THE SOLUTION!!! You have to go into TYPE PROPERTIES and change vertical and horizontal grid values from FIXED NUMBER to NONE to delete grids. So simple right? I don't know if you guys were telling me this but if you did I probably couldn't understand all the jargon.

[barthbradley]

@gnarkill283: Seriously, Dude?! Look at the very first post you got from @ToanDN. 

Also: look at these 2 screenshots. They demonstrate how using constraints will work as well (the second post reply). 

[gnarkill283]

Yea seriously. I read his post multiple times. He never said go into type properties. I didn't know anything about fixed distance vs fixed number vs none - I didn't even know that existed since its buried in the type properties. That's why you need to treat people here as complete newbies.
