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.

Which dimension tool in Pro are you using that will automatically dimension to the center and follow the drain when moved?

I'd just redraw since it's a simple plan. Set your defaults to start. Draw first, second, then basement.
