Summary0033481: Bad result with BRepAlgoAPI_Common
DescriptionHi !

BRepAlgoAPI_Common gives no result although there is clearly a big common part between 2 shapes (see attached picture)
Steps To ReproduceYou can use Tool and Argument attached in "".
Additional information
and documentation updates
A very slight transformation in Z of one shape give the right result. You can check with Argument and Tool in "".

It looks like the result is bad when the shapes are perfectly aligned in Z (see picture).

It seems that "curves" value in myDS can be wrong.

Behaviour between good case and bad case is different in getBoundPaves (hierarchy is PutBoundPaveOnCurve / MakeBlocks / ... / IntersectShapes) : vertex and point compared are sometimes too different.
TagsNo tags attached.
