Open Help, search winders.

Using the Room Divider wall, create a room shaped like you want the stairs. Draw the stairs within this room. Set the stairs to Winders. Move the 4 walls and stairs close, but not touching the deck.

You have a Framing, General layer that you could turn off. If that doesn't work, ask your architect to provide a copy with framing removed. With Architectural, you cannot edit/delete framing (except for deck framing).

Yes I would try a Custom Backsplash for the arches. Draw it against the wall, select it and move it out to the face of the cabinet. Search in Tips & Techniques for Backsplash to see more info. You cannot.

Define a new wall type.

Check out the terrain tools for your gravel.

You are in the wrong place. The Chief forum is here: https://chieftalk.chiefarchitect.com/

What are you wanting to do?

@Pro2023UserMatt Did you give up?

And you might want to do the same with the foundation -- leave Auto Rebuild on.

Rebuild the roof. Suggest you leave Auto Rebuild Roofs checked.

In this program, you will always have an Attic level, and even an actual home built using trusses for the roof has an attic, it's just not as useable as a stick built roof. For many questions, and this is one of them, attaching your plan file will help someone help you. So many possible settings and ways of doing things, having the file eliminates lots of back and fourth. 14MB size limit. Zip or remove unneeded things like furniture, cars etc. if it's larger. Close the program before zipping and attaching.

I'll guess, and guess is all I can do since all I have to go on is what's above. You are looking at this much like you would when actually building. You have a tall empty building and you want to build a two story structure within it. You would build your new walls on the slab, so you try to do the same in the program, drawing walls on the foundation level. And you probably do not have a 2nd level in your model because you don't see it as a 2nd floor, but rather just a room above another that all fits within the larger structure. Because of these things, I suggested you watch a video or three to see how the program works. You won't learn how to do exactly what you want, but you will learn the concepts, and then be able to apply them to your project. I'm certain the step by step instructions I provided above will get you started. Please start a new thread with questions unrelated to your OP.

Start a new plan. Do not make any changes to defaults. Draw four walls to form a room. Don't worry about exact dimensions. Open the resulting room and set it to be a Garage. Do not make any changes to any settings. Build a foundation. Make sure Walls With Footings is selected, but make no other changes. On the 1st level, draw a wall dividing the room. Select the wall and copy it. Build a 2nd floor taking all the defaults. Paste/Hold Position to paste the copied wall on the 2nd floor. Open one of the rooms and change its room type to Open Below. Take a Doll House View and see what you built. ----------------- As an alternate method, instead of using an Open Below room on the 2nd level, raise the ceiling in the 1st floor room. Experiment a bit to see which method works for your application. Framing will change, if that's important. ----------------- Now start over setting defaults before drawing anything, and at each step (like when you build a 2nd floor), make changes as required. ----------------- I had about 30 years working in IT when I started with Home Designer, but I think the only carryover was knowing how to learn new software. I was lucky I suppose, as I picked up this software fairly quickly, but I probably spent 40 hours of study in the beginning. Something that has always worked for me is to start small and simple. Once I understand that, slowly add and/or change things, pausing as needed to learn and/or experiment before moving forward.

You are limited by the tools you have in Pro, and it sounds like you are doing things the only way possible. There may be better ways to do individual things in your process, but it's difficult to recommend anything without seeing your steps. Suggest you ask specific questions if you feel like something could be done better. Attach a simple plan that shows a typical structure, and the corresponding layouts showing what you want. Some will build the basement on floor 1, and the foundation (footings etc) on floor 0. This is mostly manual, but it seems to give more control. I'm not here to sell you on an upgrade to Chief, but here is a comment I made earlier today on some of its capabilities.

What you see is what you get. No way to "snap" individual parts together to create a new fixture. Best you can do is manually place them together, then create an Architectural Block so they are easier to position.

Should work either place.

I believe the dashed lines are controlled by the Layer. Even if you set a wall to have all blank lines, you still get the dashed lines when you make it invisible. In Chief, you can place the wall on a unique layer and control the lines, setting them to blank and the wall will not show.

It's really helpful to include info like this when you ask a question. I'd use a mask to cover the wall.

Watch a video or two and you will see how the program is intended to work, and will be able to answer your own questions. Having an actual foundation gives you dimensions. Here is what I would do. Using the CAD tools, trace the exterior of your foundation. Copy that line to a new plan. Draw walls (they will snap to the CAD lines). Build the foundation. Adjust things as required filling in interior walls etc. But first, I would watch that video so you understand the process (big picture).
