Is this in all plans? Upload the problem plan -- zip if needed and/or delete things to meet the 14MB size limit, and someone will check it. There should be a Repair option when you reinstall. I'd try it first.

Always say what year -- Pro 2018 for example. In plan or a camera view? I guess you have closed and restarted Pro, and tested a new plan?

That should be automatic using the default wall types. Have you built all framing and verified it's not there?

Pro 2024 doesn't have the problem. The Shelf Ceiling feature when first introduced was somewhat buggy. If you are using the software in a business, I'll suggest you stay current. One of the rather stupid policies of Chief Architect is they sometimes fix problems in new versions, but don't update older ones.

Find a molding profile in the library -- look in (download) bonus catalogs too. In a camera view, click the molding in the library, then click the object you want to change. Painting (or staining) works the same, or select the object, open it and change in Materials.

Because you did not build roof framing (the trusses), or any other framing.

Open Help, search joist direction.

Blinds are typically applied through the window dialog. They will automatically resize to fill the window. If you click on a blind in the Library Browser, then click on a window to apply it, it gets applied as a curtain. If you click on a wall, it gets applied as a stand alone fixture that you can manually move into place, and resize as needed.

You probably have an invisible attic wall there. Go to the A level and check. Delete the invisible wall and it should rebuild as expected.

The 4' dimension is a Temporary Dimension from CAD to a Terrain Perimeter. Just keep repeating to yourself -- Pro isn't Solidworks. You need to learn the Home Designer way just as you learned the Solidworks way. Those inexperienced in CAD usually have the easiest time learning as they don't know how things should be done

When I bought Pro 10 years ago, one of the ways I learned the program was opening a dialog -- like Defaults. then clicking through each item. My goal was not to actually learn everything, but instead, I just wanted to become familiar with the program. I tried to remember the terminology -- what things were called, so I could look things up in help, or search online, when needed.

Using your plan opened in Pro 2025, I painted the strip -- or the 2 strips that were there. The Room Divider gets converted by the program to an interior-4 wall. In Pro, it paints without a problem. I don't have Suite 2025 to test, but it should work the same.

What's the problem? What results are you getting and what do you expect? If you will attach a simple plan (the plan file -- not an image of the plan) that demonstrates the problem, it will make troubleshooting much easier.

Forum search for tray ceiling should show some options. Why do you need/want to show framing? Boxing down to create a tray is normally not structural, and any framer will know how to do one.
