Slicing KO with shape surface

[yvanblanchard]

Hello,

I tried to slice a STEP surface (gyroid) using that way:
STEPToXSection.exe -i %stepFile% -o GyroSeul.ply -f xyz -d 0.01 -p 1.0,0.0,0.0,0
but the output ply file is empty.

STEP file:
gyroide surf seule.zip

It appears that my issue (intersection failure) is related to my input shape: it's a surface, and not a solid. It seems that "BRepAlgoAPI_Section" with a TopoDS_Shape as surface does not work.
Do you think it would be possible to change/extend that in your code ?
Thank you
