gap between panel and mullion

[saleemaniyas]

Hi all,

 I want to give a gap of 15 mm between the curtain panel mullion. how can I create it? I created a family that included glass and the mullion with a gap but it acts as a single-family so I didn't get the exact schedule. could you please help me to find this

Welcome @saleemaniyas 

I understand you have created family which includes panel and mullion in it, if you add the parameter for gap between them you can schedule the same. 

In case you have added a nested family, then you need to check the shared to schedule review the help https://knowledge.autodesk.com/support/revit/learn-explore/caas/CloudHelp/cloudhelp/2020/ENU/Revit-C...

but if I create a custom curtain panel family with the exact mullion profile and gap, can we get a separate schedule?

because it acts as a single-family.

Model your curtain panel family with a fixed gap to the left and right ref planes.

Sounds like this is fundamentally about Scheduling?  I wouldn't Model the Glazing (Panel) and Mullion in one Family.  I would build the Curtain Wall inside the Project using a Mullion and Panel Family Components - both of which are Schedulable.  Regarding the 15mm gap between the Panel and the Mullions; there's got to be something going on there besides air.   I would describe whatever it is through Details and forget about actually modeling the 15mm gap.  Frankly, a 15mm gap may be even be identifiable in the View once Thin Lines is turned OFF. You can definitely account for the gaps in Scheduling though via a simple Calculated Parameter. 

FWIW.

HI,
Thanks for your reply,
I created it according to that, but it act a single-family.in schedule

Unless you have modeled both in the same family or you are scheduling them as Walls, they are 2 different categories and you should be able to schedule separately... ie:

• Panels schedule under Curtain Panels
• Mullions under Curtain wall Mullions

See below GIF for Custom Panel

Hi,

I uploaded 2 photos, one is the glass panel family which I created it has a gap I mentioned in the family creation. the second one is that after adding a mullion, the gap becomes more it's deducting the mullion width. I need only the gap which I mentioned in the family. how can I do that ?

[saleemaniyas]

these are the 2 photos 

[saleemaniyas]

this one

@saleemaniyas 

There are no photos attached to your replies...did the GIF clarify the gap in the panel family?

[saleemaniyas]

[saleemaniyas]

the first one is without adding the mullion

second one is added the mullion and it's deducted from the length of the glass

[saleemaniyas]

oh sorry the first one has added the mullion and the second one is without mullion

@saleemaniyas 

Can you sketch what exactly you want to have?

[saleemaniyas]

Here is the glass and the mullion profile. after adding the mullion, its deducts 15mm + mullion width from the glass.

How did you model the mullions?? The panel should basically stops where the mullion profile cute the Center Plane Interior/Exterior... ie: with the panel shown in the previous GIF, you should achieve the same result

See Below GIF as well as the Revit file (v.2022)

Note: the border mullions always fall within the boundary limits of the curtain wall...ie: when you add them, the glass will automatically adjust. If you want to fix the glass size, then you would need to 

1. Either stretch the length of the Curtain wall by x2 the mullion width/base
2. Or use nested curtain walls 
   • first for the border frame
   • second/nested for the Glass infill

thank you, I will try to create as you said

We work in actual architecture offices, every day. I, like the OP, have a good reason why I'd like the mullion to have a 1/2" gap at the rough opening. We seasoned architects and designers don't need a reminder that something (sealant, backer rod, etc) will ultimately be placed in that gap. 

So if you don't have an answer to our question, consider not contributing at all. Or try this, "Sorry, there's no way to do that in Revit. We'll take note and add that to the next version." That would be better than gaslighting us in our own areas of expertise. 

Maybe Autodesk can replace the condescending explainers with Chat GPT? That would probably eliminate the ocean on non-sequiturs in these threads- not to mention be a better data collection tool for the developers.

That is quite easily achievable using the nested curtain wall approach.  See @RDAOU post above.
