R.I.Revit unable to analyze curtain system and cannot identify elements

So in Revit 2025, I have installed the stable release R.I.R

Trying to select the revit curtain wall using the ‘Graphical Element‘ - Revit component inside grasshopper, but when connected to the ‘Analyse Curtain wall type‘ component there appears to a break point error

Well the component is executed after ignoring the error but,

The Inspect element cannot retrieve any data as a result of the break point error

So could any of the experts care to explain the problem which is happening here

Thank you in advance !!

Hi Vasanth C,

Thanks for reporting, that component needs some additional error handling.

If you are using a Curtain Wall Type that is undefined get info from the Instance vs the Type.

Hi Japhy

Sadly while having the ‘Element Type’ connected to the ‘Graphical Element’ throws the same ‘Breakpoint error‘

Cannot move besides these

Thank you for taking your time to return with a possible solution, but it didnt quite workout here :frowning:

Hello Japhy, would uninstalling the present stable release of Rhino.Inside.Revit installed currently and going with latest builds help resolve the situation by NOT throwing the breakpoint errors?

Thank you and much value your help!

Hi @Vasanth_C ,

I would recommend using the latest build. I have just tested the same workflow and everything went well without any Breakpoints.

Thank you Muhammad,

Can I ask?

Is it Revit 2025.4 or Revit 25 you have used to get no errors, it’s the parameter type error which comes when R.I.R is been trying to access Revit 25’s API or atleast that was the case for me

Also, could you share the Revit version which you have used to obtain the outcome without any issues

Appreciate your help on this, thanks a lot!

Yes I am using RVT 2025.4, with latest version of RIR

Quite Unlucky here


I’ve been passing the type to the ‘Analyze curtain wall type‘ component, despite that the error has been consistenly the same from the start

Revit- 2025.4
Rhino - Latest Build
R.I.R- W.I.P Build

Dont know how to actually get to next stages

Going for Revit 2024, now

Thank you for your help , so far

Can you send me your Revit and grasshopper files?

Thank you Muhammad for this help

Still i could not get it resolved, will provide the files for you to go through

Most probably it shall work on your PC I guess , because it’s simply a Element Type has to be read by the ‘Analyze Curtain Wall‘ component , but the below image shows what happened every time when i used ‘Element Type‘ to pass in the ‘Type‘ as a Data to ‘Analyze Curtain Wall‘

It throws the same error

The .rvt file is Revit 2025
The .gh file is the latest stable build of GH

curve_based_curtain_wall.gh (21.9 KB)

curve_based_curtain_wall_rvt_25.rvt (6.5 MB)

Thanks Vaasanth C,

What is the overall goal of analyzing the Type?

Hey Japhy!

Thanks for your help initially!

The Goal was to actually select a ‘Curtain Panel Family‘ and have its parameters by ‘Inspect elements‘ component and other GH components, so it’s just a basic facade automation

Like this one

But first problem being that the curtain wall type has to be recognised in order to be going to the next stages

Thank you!

You’ll want to access the instance of the Curtain Wall, not the Type.

Sure Japhy, that’s nice to know

If I can get the ‘Analyse Curtain Wall Type‘ recognise , sure i shall use the ‘Inspect Element‘ to find the parameters, then manipulate them, and yes I should be having a family where that specific parameter is an Instance based parameter, so to have many values

But all can happen once if the first ‘Analyse Curtain Wall Type‘ component be able to read the ‘‘Element type‘ from the ‘Graphical Element‘- which has the Curtain Wall on it

Thank you for the share

ive tried using the ‘analyze curtain wall‘ component from the old 2021_GH_V1 script and it did recognize the graphical element which was referencing the revit curtain wall

so able to inspect and bend the parameters to my will inside the curtain wall

thank you for you help,

but the ‘breakpoint error‘ still persists as it did before for the latest release in the curtain wall
—-
’Graphical Element’-referencing Revit Curtain wall unable to be detected by the ‘Analyze Curtain Wall Type‘

Hope it resolves soon!
