I just gave you an upvote to balance out the downvote. I can't see any reason for the downvote, but people are different.

Well the post was from an 80 year old designer.

Another way this can be done is to create a separate as built plan file then use that file as a reference plan using glass house or some other colour scheme. This has the additional benefit of being able to toggle the reference layer set on and off for different plan views.

Nice! You nailed it Gene.

Does that mean I have to pay 25% more to see the video? ;-)

Unfortunately your link requires a sign in. So it doesn't seem to work for this forum, unless I am overlooking something.

This was completed by going to the attic view in plan, drawing the default siding over the lower wall, and then manually editing the wall shape. Vaulted Porch Ceiling.plan

When I reread your post that is pretty clear. (face palms) It can be done, but yes, I agree that is one of the tricker things to do in CA. Sometime I wish the program would stop trying to be smarter than the designer.

The cathedral gable is supported by bracing in the overhanging roof and ceiling either side of the gable. Not really your situation. You could do cables across the bottom of the gable to resist the lateral force. The beam in this gable is just for show really.

Are you referring to a trougher like a utility fluorescent style light? A 2 x 4?

here is a link to curved stairs. If you do a search on youtube for Chief Architect I am sure you will find many more https://www.chiefarchitect.com/videos/watch/388/drawing-curved-stairs.html?playlist=89

Try posting the plan file so that others can try to find what you are actually seeing. Also it might be a good idea to post a screen shot of some of the views where you are trying to see the bonus room.

Do you have two floors defined?

Maybe post your plan file, along with a sketch of what you are trying to accomplish. Just a suggestion.
