Here is a plan showing how it could be done. wh.plan

Happens to me all the time, and is always frustrating to fix. To provide the best solution, we need to know more about your plan, but here are a couple of ideas. In all cases, try to get the walls set as needed, then build the roof. Roof Cuts Wall at Bottom. This lets you have a wall on top of the roof, and no wall below. Lower Wall Type if Split by Butting Roof. Adds a different type of wall below -- say, an interior wall. Roof planes need to split the wall, not butt against it. The roof plane often needs to be modified as shown here where I moved part of it back. You could also add 2nd floor. The raised gable in front could have a second floor as the raised part. It all depends on what the inside needs to look like.

Your plan did not attach, and LawB10 did not post any images to this thread. Were you referring to this one? I believe that was done with manual roofs. Delete the roof planes that slope down to the atrium, and extend the outer ones up. You might also try adding a second floor with a single room above the atrium. Make it Open Below and no roof. The auto build roof function may do what you want.

Your 1st floor, floor structure is only 3/4".

Could you post some images showing the specific issues?

Using the Slab Tool works perfectly. Tech support must not have understood what you wanted to do.

I did, basically, what you did to form the bump out on the porch. Just turned off the floor by defining the room as Open Below. Draw in 3 Room Divider walls to enclose the steps. Make sure a room is created and you will get the roof.

Did you have a question somewhere in there? Building the bay manually is the way to go, and there is no reason floor and ceiling to not match the adjoining room. It does not need to be separated by an invisible wall from the rest of the room if floor and ceiling heights are the same.

Does Suite have this?

Open the elevation in the layout, Suppress Label.

?

What do you want the roof to look like? To mirror the plan, I'd use Edit Area as David shows in the video, but use Copy, Reflect About the common wall. If you want an air gap, draw a CAD line parallel to the common wall and reflect about it.

Post the plan?

Have you set the garage as a Garage room type? That will get you a slab.

Soffit on a half wall.

I'd use a custom countertop, or soffit instead of a shelf.

That should be automatic. Post the plan for best ideas.

Make that room a (room type) Porch to fix the floor and other things.

As I suspected the lights are hidden by a soffit.Drop them down 150mm.

Post the plan. You can use Edit>Edit Area> Edit Area (All Floors) to copy the area around the lights into a new plan if you wish.

Not perfect, but you can place a ramp over stairs.

Thanks Frank.

Do you have Ramp under the Stair icon? Do you have the Wedge shape in the library? What type of ramp do you want to model?

You cannot control the siding, which comes to the top of the foundation. See the Knowledge Base for ideas on placing a skirtboard. Look under Walls, 1st and 3rd topics.
