Hi @mostapha.
The PO_ModelEditor command is missing in my Rhino8.
It’s probably not interlinked, but when I try to load the .gem file into the Model Editor desktop app i get the following error in the log:
2025.09.29 11:05:45.636|error|import_file failed. Error message: Error: Traceback (most recent call last):

I updated to PO.V1.65.21.0 and got the PO_ModelEditor command back into Rhino8, but the Model Editor now turns up “blank”.
Hi @mosti,
Try to right click and refresh the page. The Model Editor needs to download several libraries the first time.
Refresh what page? I cannot refresh the ModelEditor, that pops up from the PO_ModelEditor Command from Rhino. It remains blank.
Hi @mosti, sorry if I was not clear.
You actually can refresh the Model Editor page. It is using the same technology as a browser. Try to right click and you should see the option.
You can also select the Model Editor page and press Ctrl + R which does the same.
Issue was resolved. It was caused by company software management, which rolls out older versions of Pollination.
