Ok here is the use-case: I'm looking for a new home. So I have some "on paper" plans.

To play with them, I got an idea: try to quickly reproduce them in sh3d with help of AI.

AI can generate a seems-good Home.xml file, leaded by by description or on image. Then I zip Home.xml (in UTF-8 without BOM) and rename it in .sh3d. And it does not work.

All my tries finish in "Unable to open" ("Impossible d'ouvrir le logement" in French).

I don't know where is the problem:
- in AI output?
- in zip compression?
- other?
