Dynamo Package Installed but Nodes Not Showing

[tuan2k6kas]

Hi everyone,

I installed the BriMohareb 2026 package from Dynamo Package Manager, but it does not seem to load properly into Dynamo. I also cannot see it in the Add-ins section, so some nodes are unavailable and cannot be used.

I already tried installing it on my friend’s PC, and it worked normally there. So I think the issue might be related to my computer or Dynamo/Revit setup.

Has anyone experienced this issue before?
Do you know what might be causing it and how to fix it?

Any help would be greatly appreciated. Thank you!

@tuan2k6kas hi, which Dynamo and revit versionsdid you use ?

[tuan2k6kas]

Hi Mr.@RMohareb . I’m using Revit 2026.3.

[RMohareb]

And dynamo version?

[tuan2k6kas]

I’m using this version.

As a first step, check your Dynamo log for any errors or mention of the package not loading.

[RMohareb]

@tuan2k6kas first you need to remove the Brimohareb_2023. that you can not load 2026 at the same time you already use 2023.

secand load Brimohareb_2026 . if it not load (that the revit 2026 use defrand dynamo rev. that for revit update servispak) use the updated pak V7.1 it compatable with Revit 2.4 Dynamo 3,6.

@RMohareb I removed and Installed updated one. Some add in appeared but I can not see Brimohareb 2026 Package on my add in tab.

[RMohareb]

can you load the Brimohareb_2026.dll file from import library

[tuan2k6kas]

1. Restart your CPU
2. Start Dynamo and confirm the package doesn’t load still
3. Quit Dynamo and Revit
4. Grab your Dynamo log file from that session
5. Grab your Dynamo settings file
6. Post the log and settings here

Hi @jacob.small, this is Log and setting file. please help me to take a look.

[jacob.small]

You still have BriMohareb_2023 installed.

1. Close Revit and Dynamo, then go to this folder and delete the package folder for both of the BriMohareb packages: C:\Users\TamNguyen\AppData\Roaming\Dynamo\Dynamo Revit\3.6\packages\
2. Then open your settings file and delete those two lines.
3. Then restart Revit and launch Dynamo.
4. Then install BriMohareb_2026 from the package manager.

[RMohareb]

1. First, please follow the @jacob.small recommendation above.

2. From your log, Dynamo cannot load assemblies related to Civil 3D or AutoCAD. This package loads DLL files from the Civil 3D and AutoCAD installation folders, so we expect that Civil 3D is already installed and configured on the user’s machine.

But first, please follow @jacob.small the recommendation above.

[tuan2k6kas]

Hi @jacob.small and @RMohareb.
I followed your instructions, but the problem is still there :((
And I already have Civil 3D installed on my PC.

@jacob.small any advice. I think other addin conflict with the pakege!

[jacob.small]

Two issues I see.

1. The package is attempting to load the aforementioned AutoCAD and Civil 3D DLLs, but we haven’t confirmed that @tuan2k6kas has a valid license. @tuan2k6kas can you open Civil 3d 2026?
2. There are a LOT of Revit add-ins noted as causing conflicts with Dynamo functionality. Including some pretty core entries (System.Core) which could cause failures all over the place. @tuan2k6kas disable all your Revit add-ins so they are unseen and not loading (check your Revit journal) and see if that resolves it.
3. If things still persist, disabled all your Dynamo customizations other than BriMohareb_2026 and see if that clears it up. If so, we know it’s a package conflict somewhere.
