<t>Sadly, there is no architect in the group of programmers of this software. None of them read a book about architecture. And none of them read even an introduction article about architecture. Then they would know the basic principles. They do not realize that the starting units of architecture ...

<t>Hi Puybaret: Thanks for the fast answer. That is a sad thing for me. I mean, in architecture there is no such structure as "room." They are spaces with boundaries of bearing structures, walls an slabs. Handling them as structures is beyond weird for me.<br/>
--You didn't say how to turn walls ...

<t>Hi: As an architect, I made multi-storey buildings in SH3D with walls, pillars, slabs and staircases, that is of bearing structures. The roofs were boxes, I could do even wavy ones.<br/>
Now I have a commission for a building with high roof with tiles. As Keet pointed out to me, you need the SH3D ...

<t>Hi Keet: Thanks for the exhaustingly detailed explanation. As usual, your input is a study object for me…<br/>
–I don't know about import/export. I just made a staircase from the "Staircases" item, clicking on the normal left-side SH3D menu, then choosing "Add to home" in the "Furniture" menu ...

<t>Hi: For me, it looks like several things are not working as it is advertised.<br/>
Now I created "Level 1" then in "Level 0" I did "Staircases>Stack top."<br/>
It is promised that "Sweet Home 3D automatically cuts a hole into the floor above." I made the slab as a box. Well, it did not done that ...

<t>Thanks! Yet again I copied your answer for study.<br/>
I am really grateful for your detailed descriptions.<br/>
What I feel now is that I will have another try, and if I am no good, then I will get some other CAD software made directly for architects. <br/>
My fault is that I can hardly wrap ...

<t>Hi: Thanks for your insights. I copied and saved your post for study, and read thru a couple of times.<br/>
--One question directly: you wrote "Last stair elevation 2.70" <br/>
I think that elevation in SH3D always means the bottom of an object.<br/>
I need last (highest) stair TOP to be 2.70. So ...

<t>Hi: As I mentioned elsewhere, I am an architect. That is the base of my problems. I think in structures, not in rooms, etc. -- Now I have a problem with the generate_staircase plugin.<br/>
--When I, as an architect start to plan a staircase, I take the vertical floorplan to floorplan distance ...

Hi: Thanks for a fantastic job! I downloaded the entire post for study and use.

<r>Thanks! The problem is that I am an architect. I do not think in rooms, I think in structures. I have done several multi-storey building with SH3D without creating a single room. This is strange thinking for me.<br/>
--Thank you very much for your insight, the Generate Roof is showing up when I ...
