Thank you, Graeme and Eric. Appreciate the feedback. I hadn't thought about the unassigned interior space being an issue - but unfortunately that did not fix the problem. I've uploaded a sample file for reference. Appreciate any insight you have on this issue, if any!
Also, I have searched this form meticulously over the past few weeks. (And have been grateful for the incredible resource that this forum is!) I have also watched countless tutorials at this point, as I'm assuming this issue is user error, but have had no luck. I do apologize if there is another post with this answered - I will continue to search here and elsewhere until I figure this out! If/when I do, I will post back for reference.
*I am trying to upload a plan but the upload keeps failing (it's only 4mb). Please excuse my naivety here - but what's the best file format to upload if not .plan?
Thank you! Framing Update 2021-09-07.plan
