Floor and wall gap
I made a test drawing of a one story house to re-learn how to use levels, walls and floors,because its seems i did not understand them.
Why is there an unexpected 1-inch gap between the 7" thick floor/ceiling and the top of the walls of the first story in this test?
Background Using SW3D 7.02 with ubuntu 18.04 Test drawing has 5 levels. Level 1 is a sub-ground level for a concrete foundation wall. Level 2 is a specifically for a 4" concrete slab floor, so the top of slab is at ground level. Level 3 is 8" high to be the concrete foundation wall above ground. Level 4 has the walls for the first story, which together with level 3 is 96" high (8 feet, floor to ceiling). Level 5 has the joists for the ceiling of the first story and is 7" thick. It is called Mezzanine and the room that represents the floor has a gap above the walls even though the measures of the levels and walls should have closed that gap.
I added an inch to the wall on the left (x=0.0 y=0.0 to x=0.0 y=30) and that is why it has no gap.

Re: Floor and wall gap
1. Read this to understand the principle. In your case I think there is some discordance between the high of the level and the high of the walls. 2. To share files probably you could use Dropbox or MediaFire or other site like this and insert hire the link.

Re: Floor and wall gap
Fist is your and second is mine correction
1. Look how the level elevation have to be calculated. 2. The level height is not the same thing with walls height which could be different. 3. The left wall of the ground floor have 89" in place of 88"

Re: Floor and wall gap
thank you very much.
RE: left wall height difference. As explained in the introduction of the thread, I added an inch to one wall to close the gap, 89 instead of 88 [just to see how much the gap was].
RE: Your suggested changes to the level information. I will go over the changes to learn from them and let you know if I figured it out.
After review of the link you sent as an explanation of levels, floors, ceilings and walls, I still could not understand floors. Perhaps because how a floor is treated is not specifically explained (I may have missed it).
To build a physical house (Canadian wood house), I make a foundation of a concrete wall on a footing (wider concrete pad), then either. add a floor of joists with covering of sheathing (subfloor) on top of the foundation wall, or a concrete slab (either on top of, or inside, the foundation wall), then put the walls on top of the subfloor or slab, then on top of that wall put joists to hold either just the ceiling (one story building) or a ceiling and a floor (multi-story building). For the multi-story building, another sets of walls is put on the second subfloor, and so on. In Sweethome, it appears that I do not add a floor (joists and subfloor) separately: which is what I was doing: until the house design in Sweethome did not match the one I made in LibreCAD. That mismatch led me here.

Re: Floor and wall gap
The gap turned out to be a math problem. sigh. The elevation of Mezzanine floor should have been 103"
What i was doing: Placed a room on top of a wall; instead of inside a wall. Placing it on top of the wall insures that the floor is on top of the wall. If the room is inside the wall then the floor is placed below the top of the wall as in the level called slab, where the concrete slab is supposed to be below elevation 0.
P.S. in the new test plan the upper mezzanine walls and ceiling were added as well as attempts at roofs. The centre roof worked. the side roofs did not. They were supposed to be a single slab 7" thick and extend at 23 degrees from mezzanine wall to a foot beyond ground floor walls. Crashed the program as usual though the roofs did not appear.

Re: Floor and wall gap
update.
I figured out the roof generation problem. I had to move the generated roof, from the Roof-Gen level it was created on, to another level. Then delete the Roof-Gen level, so the roof generation program could create a new Roof-Gen level for the next roof.
Sorry to mix too thread issues into one. I only do that because Dorin is on this thread, and he will be frustrated that I did not follow all the instructions.

Re: Floor and wall gap
I don't know how others handle this but I use the generated roof-gen level to save the room that was used to create the roof. After generating the roof I move it like you did to the correct level and move the room that was the source to the roof-gen level (after naming it). Then I make the roof-gen level unviewable. That way the source-room is saved for a possible re-generation without interfering with the rest of the plan. With multiple rooms/roofs I just collect the rooms on that same roof-gen level en delete extra roof-gen levels that appeared.
