Summary

0032287: Modeling Algorithms - mkoffset creates float numbers precision size edges

Description

Some mkoffset's tests creates float numbers presition size edges.
For example:
start point coord: -35.0471942222598 -36.8621970324173 22.9584554097165
end point coord: -35.0471941490652 -36.8621969901583 22.9584554118939
In branch CR23731_7 the shapes have faulty result of the checkshape command, but fixshape command fix this problem.

Steps To Reproduce

pload MODELING
set env(CSF_TestDataPath) "//salomer001/dn62/occt_tests_data"
brestore [locate_data_file offset_wire_078.brep] s
mkoffset result s 1 -2.367635
# "Faulty shapes in variables faulty_1 to faulty_2" in output
checkshape result_1
fixshape result_fix result_1
# "This shape seems to be valid" in output
checkshape result_fix
