When I added rooms by Select Geometries, some of the rooms were modelled upside down. I can manually change the Face Type (Floor/RoofCeiling), but I’m just wondering how Pollination recognises whether the face is Floor or RoofCeiling.
Is there any way to prevent this error in advance?
Hi @keigonomura,
Thank you for reporting the issue. If you use the Rhino plugin to create the rooms, this should not be happening in the first place. I consider this a bug that we should fix on our end. Do you have a sample file that we can use to recreate the error?
Good to hear that.
Sorry, but I have already fixed the upside-down. The room was created from a 2D polyline with our GH scripts which are similar to “Draw a Room” in Pollination Rhino Plugin, but different scripts. Probably, that’s the cause. Only 2 upside-down rooms out of 1100 rooms, which is acceptable.
Thank you, @keigonomura!
I’ll mark this as solved for now but unless we exactly know why this is happening, I actually consider this unacceptable! 
It is fine to have minor bugs but as long as the bugs are predictable, so the user expects them and knows how to go around them until we push a fix. In this case, it is random, and we don’t know when to expect it. That makes it unacceptable!
Feel free to re-open this issue if you faced it again. It should be an easy fix once we can recreate it on our end. Thanks!
