Summary0032440: Modeling Algorithms - Boolean operation produces correct/incorrect result depending on the order of the input arguments
DescriptionBoolean operation for the following shapes(base, topo, sand, river) produces
14 solids and 18 shells(what is correct).

But if we perform this operation in parts we might get incorrect result depending on the order of the input arguments: 8 solids 12 shells
Steps To Reproduce
box base 178 230 322 1302 500 1138

restore topo.brep topo
restore sand.brep sand
restore river.brep river

# Cut1 base by topology
bclearobjects
baddobjects base topo
bapibuild base1

# Cut2 base1 by sand
bclearobjects
baddobjects sand base1
# But in this case the pipeline will produce correct result!!!!!!!!
# baddobjects base1 sand
bapibuild base2

# Cut3 base2 by river
bclearobjects
baddobjects base2 river
bapibuild base3

# Expected 14 solids but get 8 solids
explode base3 So

# Expected 18 shells but get 12 shells
explode base3 Sh
