Hello community, I am seeking assistance in creating a script that will enable me to accurately place T-bars in the acoustical ceiling within Revit rather than just displaying lines.
Thank you.
Welcome to the community!
Generally speaking, this is a âhelp us help youâ sort of forum. Everyone that responds is volunteering a bit of their time to help, so if you have any progress started on your script or thoughts about how to implement what youâre looking to do, thatâs going to go a long way to getting a timely response back.
A few questions since I donât usually do ceiling systems.
What does a t-bar family look like? Do they need to replicate the wall-to-wall dimension of the display lines youâd see in Revit?
Is it general practice that you center the tiles on the centerpoint of the room to minimize tile usage?
The last time I looked into ceiling systems (as part of trying to place air terminals), I donât believe the line elements in the ceiling systems were accessible.
Some context (from 2018). At that point in time, the fill pattern lines werenât exposed to the API. I canât find threads that suggest thatâs changed since. So you have to replicate the logic in your script instead of lifting the lines directly.
If youâre following the strategy of reducing tiles used, you can replicate the lines yourself based on knowing the center of the room, the perimeter boundary of the room, and the X/Y spacing of the lines.

Hereâs a good explanation by @Vikram_Subbaiah that can walk you through the logic of where the teebar goes to optimize tile usage.
Itâs not directly exposed, but there is some funkiness with Stable Representations that you can use to get at this. The link below is with regard to getting references for dimensions, but you can use similar tricks to get geometry to create Revit elements form. I had a little project in early stages I was playing around with to place a setout marker and dimensions for ceiling tile setouts, and also to be able to provide model line elements on grids so I could see the grids in Navisworks/Revizto/etc where the Revit surface pattern doesnât get exported, so it should be doable.

One simpler possibility to try could be to stick to Revit tools and do something using sloped glazing to create your ceiling tiles as curtain panels and t bars as mullions.
Hi @palvarado probably something here could help
@sovitek I was not able to find the âCeiling.getceilingBoundaryâ and the âCeiling.GetGridCurvesâ nodes. Where can I get those nodes?
Thanks for your help
yeah sure its from sparrow package. hope it could work âŚps intead of given a link as i do just give a null in active document and works great for links as well if that you want
Iâve managed to create the Gridlines and boundaries of the ceiling in 2D using the script. However, Iâm now looking to add a T-bar component to each grid of the ceiling within the same script. Could you please advise me on how to do this?
I sent you a link where you can download the ceiling T-bar component.

Thank you in advance for your assistance.

Hi you are welcome, could you show your graph as an image, so far you are now, you know many lazy people in here 
allright try something here and lets us know how it worksâŚi use clockwork for line based family, and keep in mind the sparrow node only works on straight boundaries
Thanks, @sovitek. I think we are almost there.
Two issues
- The T-Bar component must be flipped, So the T must be at the bottom of the ceiling. Right now, it is at the top.
The T-Bar components should be positioned between the ceiling rather than below it.
Moreover,
When adding the T-bar component to a linked file, should I choose the link that has the ceilings and will be compatible? Typically, I include the T-bars in linked files.
Thank you so much for your help.
Hi.do you mean something hereâŚits on a link ?
Hello, I plan to utilize this script to install T-bars on acoustical ceilings that are included in a Revit link.
- Can you place the T-Bars in between the ceiling tiles at the same elevation as the ones at the edges?
Thank you!
Im not sure what you wanna plan, until now the community tried help,we dont cant see any example nothingâŚplease show !!! it isnt a " do my job session
Yes it will work on link if you feed in a linkinstance as you doâŚfor select the ceiling then use spring select link elementâŚ

Hi @sovitek this is what I have so far. I think I have something wrong in my script. it is not working with the Revit link.
Do you see where is my problem?
