Summary0033166: BRepOffset_MakeOffset fails to build joints in intersection mode
DescriptionCurrently result of test "bugs modalg_7 bug30054" is OK.
But result is really invalid and contains some invalid faces (see example on picture), which has not closed wires and very large vertex and edges tolerances in order to fill gaps.
It is necessary to fix real problems of offset algorithm instead of increasing tolerances of subshapes.
Steps To ReproduceRun test "bugs modalg_7 bug30054"
or, using attached file of issue 0030054:

restore RectLoft.brep sh
thickshell result sh 1 i

and then explode result on faces.
result_4, 5, 6, 7, 8, 9, 11, 12 are bad faces with gaps
TagsNo tags attached.
