Hello everyone,

I’m trying out the Pollination workflow on a Revit project, but I’m currently stuck at the “Select Windows” step. Strangely, the panel doesn’t show any windows or panels to select, and the “Filter by Level” dropdown is completely empty.

To troubleshoot, I tried unchecking the “Windows” category in the Visibility/Graphics Overrides, and the windows in my 3D view did disappear — which suggests that the plugin is recognizing them as windows.

I also tested the Export Rooms function, and it works fine. I can see the room boundaries, and it seems like the windows are indeed placed along those boundaries.

I’m not sure what’s causing this issue. Has anyone experienced something similar or knows how to fix it? Thanks in advance for your help!

Hi @dydhuy,

Welcome to the forum. Sorry about the issue.

  1. Do you see any issues in the logs?
  2. Can you try the latest developer version of the Revit plugin? You can download it from here.
  3. If that doesn’t solve the problem, can you share the Revit model with us?

@dydhuy, one more suggestion. What happens if you disable the Level Filter? It looks like we have introduced a bug in the latest developer version.

Sorry about that.

Hi @mostapha, Thank you for your reply. I reopened this project and it worked nicely :grinning_face:. I think it might just be a bug.

I have another question. After exporting the HBJSON file and opening it in Grasshopper, I tried to add “shade” elements (extrusions such as window sill, jamb) to get more accurate results for the daylight simulation. However the HBJSON model seems to be a single, integrated object (Model 1: Building 1) and I can’t break it down into individual rooms for modification. What would be the best way to model this? Do I have to use Pollination in Rhino? Or it is something I can directly edit in GH? Or I missed any settings in Pollination Revit?

Thanks in advance :grinning_face:

Hi @dydhuy,

I see. That’s the expected behavior. We should probably have a better warning for it, but if you open a detached file and save it as a central file, then you need to close and re-open the file.

You need to deconstruct the model first.

What’s your desired workflow here? You could use the Pollination Rhino plugin, which has a command for doing the same operation.

Hello Pollination Team,

I have installed the latest version of the Revit plugin, but I am getting this error:

“Unknown License! Unknown message!”

This issue started when I opened the Export Windows/Doors tab, the window was empty and there was nothing to select. I came here nd saw a message from Mr. Mustafa recommending to download the latest version, if anyone encounters this problem.

After I installed the latest version, this license error began appearing.

My email is: hagermamdouh201@gmail.com

I was on the trial period, and now I cannot use the plugin. Could you please help me reset or activate my license so I can continue my work.

and check if after you solve the license issue for me to login. I’ll counter the same blank Window/Doors window again!!

Thank you so much in advance for your support.

Best regards,
Hagar Mamdouh
