Summary0024790: Modeling Algorithms - missing intersection curve between two surfaces
DescriptionMissing intersection curve between two surfaces: the section is not closed.
Steps To ReproduceUse the following commands to reproduce the problem:
pload MODELING

#
restore fz33.brep b1
restore fz46.brep b2
bop b1 b2
bopsection res

#
mksurface s1 b1
mksurface s2 b2

intersect i s1 s2
#
# Result:
# The One intersection curve "i".
# But there should be two intersection curves "i_1, i_2"
TagsNo tags attached.

The problem exists on current master. Note that bopsection produces visibly complete section (two edges)

On the current MASTER:

1. The bopsection result is OK.
2. The intersection result is incomplete as before.

In Adaptor3d/Adaptor3d_TopolTool.cxx - Increased the minimum number of sample points for BSpline surfaces to get the missing intersection curve. Several regressions have been found (IR-2022-11-28) that need to be fixed.
