Footprint not correctly interpreted

[ebsbR95]

Hello,
Thank you for your work on this tool. It’s been really helpful.

I am experiencing an issue when trying to reconstruct a building using City3D with a custom footprint. The footprint appears valid in QGIS (see screenshot), but when loaded into City3D, it is not interpreted correctly. As a result, the reconstruction fails.

Could you please help me identify why the footprint is not being processed correctly?

I suggest you try to tune some of the parameters (might be hardcoded in the code - sorry for this. Just a research prototype).
You're also encouraged to read our paper to get familiar with technical details. Then it would be easier to tune the parameters and understand the advantages and limitations of the method.
