0032273: Data Exchange - STEP Export producing bad geometry from BREP Files
Dear OCCT team,

I have several BREP Files which seems broken when I export them in STEP.

I tried OCCT 7.5.0 and 7.6.0.
Others Tools : ShapeFix_Face, ShapeFix_FixSmallFace, ShapeFix_Shape ...
The ShapeFix_Wireframe(FixGaps3d) resolved the problem for other volumes but not this one.

Thank you for your help

pload XDE MODELING
restore initial.brep initial
testwritestep tostep.stp initial
testreadstep  tostep.stp new
I changed those global configuration variable and tried to tweak with it but to no avail.
("write.surfacecurve.mode",0);
("read.precision.mode",1);
("write.precision.val",0.01);
("write.step.assembly",0);
No tags attached.
