Summary0028700: BRepBuilderAPI_Sewing produces too small edge covered by its vertices
DescriptionThis bug has been discovered during fixing #23731 as a regression on several test cases. The current version of checkshape does not report such invalidity. However, there is the method BRepLib::FindValidRange() that allows to check the edge for validity in respect to this rule.
It is needed to analyze these test cases and understand whether the sewing algorithm must be corrected.

In Draw, the following command checks if the shape contains to small edges:

foreach e [explode a e] {
  if {[validrange $e] == "edge has no valid range"} {
    puts "Error: edge $e is too small"
  }
}
