I imaging you want 2 roof planes and not 3. The one on the front side should be contiguous and not divided. Delete the one shown on the 1st floor, drag the one above across.

The error message says it all. See if you can find the missing item in this list and replace it.

Where is that?

In Home Designer, all imported symbols like your door handle are imported as a symbol type Fixture and that cannot be changed. To make your handle available to a cabinet, it needs to be a symbol type Hardware. Changing the Component ID does not do this (that info is for the Materials List). You will need to manually place the handle on the cabinet.

What's the problem?

@MadMacks This shows what y-g-m-n said above.

Open Help, search stairs. That panel is set to attach to the surface, and not recess. Check the 3D Warehouse (google it) for symbols you might use.

Where is your roof?

Use a Glass House view to look at the back of the cabinet. And why are you asking? Are you seeing a problem?

When you reference a video, it helps to provide a link.

Think about the instructions you are giving the program. See if this gives you an idea.

Using the Foundation Wall tool, draw the footers on the foundation level.

Home Designer does not have the settings to directly change the roof structure to do what you want. If it's important, you could hire someone (not me) with Chief to create the roof structure. They would not need to draw anything, just set roof defaults.

What's the problem? Attaching a picture (screen capture) often helps. Please see this thread for some tips: https://hometalk.chiefarchitect.com/topic/8582-getting-started-with-hometalk/

Only the parametric doors will automatically conform to an arch. Doors from the library will not change shape.

Helpful to have an image of the chimney shape. Probably better ways to model than using a backsplash.

@CrossFireDesign A couple of tips. 1) Start a new thread when you have a question. 2) Attach your plan file after closing Pro. Zip if needed. Helps prevent a bunch of back and fourth, or someone like me having to enumerate (guess) at all the possibilities. 3) Pay attention to your settings. Here you have set the OSB to be framing and lumber. And you should have auto rebuild framing on -- framing settings are not dynamic.

You have a bunch of things going on so I'll give you a couple of pointers. I don't see where you said, but I'll assume you are using manual roof planes. If you lower the ceiling height in that central space, some of your wall problems might go away. What you should do when drawing manual roof planes is to set the ceiling height correctly, then draw the roof. The roof will then be in the correct position. Video on my YouTube channel (link in my signature) about making settings correct than drawing the roof. You also have the option to build a 2nd floor over the 2 outside spaces and set them to be Open Below. That can sometimes help, but it depends on where you are going with the model. The program isn't smart enough to always fill in exterior wall gaps. It wants a wall below to know what to build above. Often you need to draw in your own walls and make settings in them to tell the program what to do. Read about Roof Cuts Wall at Bottom, and Lower Wall Type When Split by Butting Roof. You usually want to select one or the other. Pictures are good, attaching your plan file (close Pro first) will help someone provide the best suggestions. When you do show multiple images, it helps to add your text that applies to the image by the image.

Did you do this too?

Custom Backsplash Make the shower pony wall No Room Definition, then drag the Room Divider across to the far wall. For some reason, these two wall types do not always join as we want. Thanks -- you did.
