Wrong result of cut operation.

Open CASCADEOCCT:Modeling Algorithmsclosed9 public notes

Description

Wrong result of cut operation.
The cut operation performed with solids provides incorrect result.

Steps to reproduce

# Use the following DRAW commands to reproduce the problem:

box a 0 0 0 10 10 10
box b 20 0 0 10 10 10

bfuse r0 a b
bcut r1 r0 a
nbshapes r1

#------------------
# The result (nbshapes r1)
Number of shapes in r1
VERTEX : 16
EDGE : 24
WIRE : 12
FACE : 12
SHELL : 2
SOLID : 2
COMPSOLID : 0
COMPOUND : 1
SHAPE : 69

# but it should be:
Number of shapes in r1
VERTEX : 8
EDGE : 12
WIRE : 6
FACE : 6
SHELL : 1
SOLID : 1
COMPSOLID : 0
COMPOUND : 1
SHAPE : 35

    no new features

    II. Changes:
    II.1. class BOPDS_Iterator
    method:
    void BOPDS_Iterator::Intersect()
    The ttreatment of solid/* interferences has been added.
    II.2 class BOPAlgo_PaveFiller
    protected methods:
    void BOPAlgo_PaveFiller::PerformVZ()
    void BOPAlgo_PaveFiller::PerformEZ()
