Hello, I’m a new user to Pollination exporting my first model from Revit to IESVE. I followed the steps and validated the model, which shows no errors or warnings, but I’m getting the following error message when exporting. It seems to be indicating a negative room volume somewhere, but I can’t tell what room. Can you help?

Do you happen to have a multi-story room in your model? My best guess is that the issue is happening because the rooms are not fully aligned and the vertical intersection after extruding the rooms is causing this issue.
Can you share the PoMF with me? You can email it to me at mostapha [at] ladybug [dot] tools or send a private message here if you don’t want to share it publicly. I can take it from there.
@mlee, I sent you an email with a recording that shows how to fix the issue. The source of the issue was the misalignments.
I keep this open for now until @chriswmackey gets a chance to review the model and see if there is a way that we can automate the process of resolving this issue or find a better way to inform the user about this issue.
