Summary0022535: Cut sphere: invalid shape after reading from STEP
DescriptionThe attached shape is a result of boolean cut operation between sphere and
cylinder. While it is correctly exported to STEP, the import operation produces
incorrect parametric representation of the face (see pcurve.png screenshot).
TagsNo tags attached.

Test case for this bug are
chl 934 U6 (for sphere_cyl2_cut.brep)
chl 934 U7 (for cut_comp.brep)
Test cases are BAD.
___________________________________________
convert from brep to step by DRAW commands:
testwritestep /tmp/aaa.stp a
stepread /tmp/aaa.stp b *
___________________________________________
We get wrong result of boolean cut operation between sphere and cylinder.

In cutting sphere it's seam edge was divided into two parts(by cylinder), but pcurves of the second were not shifted during shape healing.

Branch CR22535 is ready to be reviewed.

Dear PDN,
Please review.

Dear MKV,

de iges_2 H1 is not regression, but improvement, because STATSHAPE was fixed, so reference data changed.

de step_1 J6 is bad file with tolerance = 1562, and one of it's invalid wires was not detected before fix, it leads to changes in number of faces, so it is not a regression too.

I think, that scripts should be updated.

Test cases are good now, the problem was in compounds (compound with only one shape is deleted during reading step) and in specialty of creation the second case where some vertices are one shape, but with different locations.
