If you view this as a problem, I'd report to Chief. I opened an older plan in 2021 and built a foundation and the footing was centered. Created a new plan and the footing was offset.

I did a quick test and things work as expected. Suggest you try with a different image -- one that you have not changed.

Change the material. Read about materials in Help.

No. Experiment with using Room Divider walls like I show.

Give it a Room Type of Unfinished. Suite doesn't do framing, so you won't see joists.

Make your shelf sized to fit, material correct, bump it against the wall, center on niche. Transform/Replicate to move it into the niche.

No

Try a cross section through the space to see what's happening. Uncheck Flat Ceiling Over This Room. Turn on Auto Rebuild Terrain.

What you submit depends on what is required. There are sample plans you can download from the Chief site that will give you some ideas, and whoever you are submitting to should also have some info. There are videos about Layout, but none that I know of that go over what is needed for a complete set of construction documents as the requirements form place to place are different.

That works the same. Select in the library, click on cabinet to place it.

When you edit a post, your edit does not trigger the forum to show something has changed. Either add the info in a new comment, or make a new comment saying that the original post was edited.

Soffit, slab, shape from the library ...

Looks like there is. Fill it in so the size looks correct.

Yes

This is the only way that I know of to do what you want. The more conventional way of doing this is using CAD to draw in plan, and a material in 3D.

Experiment with importing an image and creating a material using the image. Use the imported image in plan, and apply the material to a flat object for your 3D view.

Read about Sloped Soffits.

You can always enter the info manually. If you want help, someone will probably need the dxf.

Where are you finding the fireplace? You can use 4 Soffits to create the surround.

Don't know what you were doing wrong, but here is what I did. Inserted a floor under your 2nd floor and defined a room on it using invisible walls. Changed the Floor Above value to lower the 3rd floor down so it's sitting on the beams. I did this mostly to produce the image so everyone understood what you wanted. I was really thinking that the beams would go on this new blank floor, but it seems they look OK as is without moving them. I would start over using a similar approach, and your concrete walls are marked as Foundation walls and probably should not be. You need to consider the final result too because decisions are additive. Looking at a problem in isolation, you might solve it, but you solution may effect something else.

Using Ctrl removes precision, and simply gives you freedom of movement. There are multiple ways to move things precisely and it often depends on which view type you are working in, and what you are wanting to position. I use Point-to-Point all the time, and frequently draw CAD lines to use in positioning objects.

Help us by showing (screen capture) what you are wanting to move and where to.

Is this what you want?

Guessing you are on the 2nd floor and the problem wall was an auto generated attic wall.
