hello,
i am trying to export a revit file as GEM for IES, and everything works perfectly till i get to the preview section. I can see all the rooms reconised but I do not get any preview of the 3D model. This is the message I am getting:
Please, can someone help me understanding how to proceed?
Thank you!
Hi @giuseppe92, Sorry about that!
Can you open the log file by clicking on the small black icon, and share the command with me? I need you to share a few files with us to be able to pinpoint the issue and fix this for you.
It looks like the command expects the hb_model to be a single file but is receiving a list. @chriswmackey, can you tell what could be the source of the error based on the error message?
Hey @mostapha ,
It also looks like @giuseppe92 is using an old version of the Revit plugin from over two months ago. I believe this fix that I pushed back in October addresses the issue:
So just updating to the latest Revit plugin should solve this case. That is, unless we have not had a stable release of the Revit plugin in over 2 months.
Thank you @mostapha and @chriswmackey,
I am asking IT to install the update and try again.
I let you know if the issue is still there.
Thank you so much 
Regards,
