I have created a building with several foor my 0 is along with the main entrance. but I also created a celar.
It difficult to create a terrain that goes down because the editor shows it one floor above.

Is it somehow possible to edit a created Terrain? At moment I have to remove it and re create ...

Nice. May I try something with ChatGPT (Im not into a developer).

Personally I think it's pretty useless because very soon a user will want to add more parameters to refine the process...

That sounds like you think it is bad.
If really someone dig into it and add more possibility into that ...

My Request would fit perfectly with: "Why simple when it can be complicated?"

I still wish the fast house creator where someone could enter inner distance for width, length and height (an user even could measure himself with a rule) and count of levels of his house and get a dummy building where ...

FreeCAD use IfcOpenShell. I use IfcConvert from IfcOpenshell to convert customer Files into step files at work.

(On IfcOpenShell Bonsai is also mentioned.)

a fast way to get a house with several floors and without rooms

Please explain me where you've see this in the real life?
Rooms mark the separation between floors. So no rooms no floors. Without rooms your furniture will levitate somewhere if you set some elevation.

I saw this with friends ...

Thank you all for your insight here.
First of all, I am not interested in editing IFC data. It's about staging rooms. As a user, I don't dare to predict how the goal of using IFC for this purpose can be meaningfully achieved. But if it is that difficult, then you can also start small and only ...

..And that's the case I ask for a "Fast House Creator" and for the IFC support . I do not ask for modify an import. I ask for use an import properly.

I do not ask for parametric design, I ask for a way to have a fast way to get a house with several floors and without rooms designed.


internal ...

No I do not assume that a IFC Building could be modified inside sh3d. But I assume to see at least the plan above. And be able to select the ground and place furniture.
A big plus would be I f I could save the IFC with the interior design I did add with sh3d.

The Problem was never to draw something.

The Problem on my side was to draw it accurate or change things. If I measure a flat and try to get the measured flat into the sh3d I get problems with drag and drop walls.
Modify a room is also a lot of work, mostly because I'm not able to measure a wall ...

If I import a Building into sh3d it would not be a problem that I could not modify the walls. That would be an extra feature. The Problem is more that the drawing is not working. As far, if I import a building, I'm not able to select a surface and say it is the ground for floor 1 or floor 2.
