creation solitude intercapedine

[MorganWheadfields]

hi to everyone, I returned with the nth ahimè stupid problem and I don't know how to operate..... I apologize beforehand for the question I'm about to ask you:

- I'm making the design of a house consisting of 3 floors in everything

- basement, raised floor, second floor (since here nothing strange)

- the basement is placed 30 cm above the ground floor; around the walls of the basement floor at the height of -2.20 meters turns the concrete loft of the intercapedine of 1 meter wide (then lies between the walls of the basement and the wall against the ground)

I designed everything on the same plant and correctly inserted the basement floor.... now I should insert the ceiling of the intercapedine which should then be inserted between the two walls (ground wall and wall) without continuing under the floor of the house (thrench style practically )

see jpg file scheme attached

Sorry, I didn't understand the problem. .
Do you have to do something that has that section in archicad?

 

[MorganWheadfields]

no the section I glued to you was to show you which were the floors I had to make. . . .

basically see the intercapedine on the side of the building?

turns as obvious tuitto around... said loft is located 40 cm below the floor of the basement floor. ....

but instead of being whole, it is only a ring around the walls of the ground and the walls of the basement

I tried to draw the loft with archicad but it makes me insert it as if it was a single surface, I can't find an option to exclude the central part.....

as you see from the attached photo, the green part is the basement floor that is located at altitude -1.70

the white part between the two walls is instead the insole of the wholepedine which is at altitude -2.10

I have to insert the ceiling of the intercapedine

Sorry, but today I'm a little out of phase... In practice you have to make a loft with a hole in the center where there is another loft at a different altitude?

I know it is a problem for the experts of archicad but I am using it for the second time and every time I clash with a different problem:-(

 

[DarthVader]

very simple then. make the big loft, draw the contours of the smaller one. click on an external loft point and click on the "-" symbol. by pressing the space bar click inside the closed line with which you have designed the inner ceiling.
At this point you have a loft with the hole inside!
by selecting again the loft tool, and with the magic wand (always space bar) and by clicking you get the new loft. at this point you just have to give the right odds
