Orient faces not showing

Hi - i am trying to fix the orientation in my model but when i go to search orient faces, i can see its there but doesn’t let me click in. Can someone help please?
Thank you

Select a face first.

Make sure it’s a single face and not a surface that you are right clicking in. Turn on Hidden Geometry to make sure.

Ahhh It is hidden geometry - what do i do next??

Ignore me! No it wasn’t…

Share the .skp file so we can see what you are working with. If it’s larger than 16 Mb upload it to DropBox or WE Transfer and share the link.

This is what is happening - i have this two tone on the walls . what is going on?

I don’t think Orient Faces is what you need to fix it but it’s hard to say exactly what is the fix without seeing the .skp file. If you don’t want to make the file available publicly feel free to send it to me privately so I can look at it. Upload it as I described. Then click on my name and then the Message button. Send me the link in a private message.
