This does not relate to your question but these new features shown in this video I think would be very useful to the type of work you do

You can turn it off in preferences also it ask when you install if you want to use it

Watch this video Railing Walls - Video | Chief Architect asuming your are still not using x8 if you are in x16 update your signature in the forum

Transform replicate tool most items have that tool in there tool bar and z is up and down in 3d space check it out it can be a precise way to move things

Ask for dwg format, 3d only allows for a symbol and you cannot edit it.

Share or upload your plan then people can give you the best solution

Yours are attacked as shown in this post

I don’t know make sure your open below room is correct and that have not changed the height setting in stair dialog

1. yes see my file i just adjusted the landings and then all worked 2. They should unless you have changed the stairs automatic setting but i think more information is needed as to your exact problem like screen shot or the file also with this question i am not a expert with stairs someone else may have a better reply

I fixed it zoom in on your landings they are overlapping each other. stair winders sample M fix.plan

The rooms on the right hand side of your plan have a lowered floor height -56 1/4" witch lowers your top plate height and roof plane pitching height as for the gaps they can be fixed by drawing attic walsl latter If you want i could do a screen share and help you if that interest you send me a private message

Try adjusting gable sub facia maybe

I agree unless there is missing information
