Summary

0026590: Inconsistent results obtained by checkshape

Description

Inconsistent results obtained by checkshape.

The results provided by checkshape differs for
inverted solid and face.

Steps To Reproduce

# Case 1.
box b 10 10 10
explode b f

invert b
checkshape b
#Result: This shape seems to be valid

invert b_5
checkshape b_5
#Result: BRepCheck_BadOrientationOfSubshape

# Case 2.
box b1 10 10 10
box b2 20 0 0 10 10 10

explode b1
explode b2
shape z So
add b1_1 z
add b2_1 z
invert z

checkshape z
#Result: This shape seems to be valid

explode b1 f
explode b2 f
explode b1_5
explode b2_5

mksurface s b1_5
mkface fs s
add b1_5_1 fs
add b2_5_1 fs

checkshape fs
# Result:
#On Shape faulty_1 :
#BRepCheck_InvalidImbricationOfWires
