  `CheckSelfIntersection`()
    - Checks self-intersection of the wire (considering pcurves) Looks for self-intersecting edges and each pair of intersecting edges. Warning: It does not check each edge with any other one (only each two adjacent edges) The order of the checks : CheckSelfIntersectingEdge, CheckIntersectingEdges Returns: True if at least one check returned True Status: FAIL1 or DONE1 - see CheckSelfIntersectingEdge FAIL2 or DONE2 - see CheckIntersectingEdges

    Return type: | bool

  `CheckShapeConnect`()
    - Checks with what orientation <shape> (wire or edge) can be connected to the wire. Tests distances with starting <preci> from <SBWD> (close confusion), but if given <prec> is greater, tests with <prec> (coarse confusion). The smallest found distance can be returned by MinDistance3d //! Returns: False if status is FAIL (see below) Status: DONE1 : If <shape> follows <SBWD>, direct sense (normal) DONE2 : If <shape> follows <SBWD>, but if reversed DONE3 : If <shape> preceeds <SBWD>, direct sense DONE4 : If <shape> preceeds <SBWD>, but if reversed FAIL1 : If <shape> is neither an edge nor a wire FAIL2 : If <shape> cannot be connected to <SBWD> //! DONE5 : To the tail of <SBWD> the <shape> is closer with direct sense DONE6 : To the head of <SBWD> the <shape> is closer with direct sense //! Remark: Statuses DONE1 - DONE4, FAIL1 - FAIL2 are basic and describe the nearest connection of the <shape> to <SBWD>. Statuses DONE5 and DONE6 are advanced and are to be used when analyzing with what sense (direct or reversed) the <shape> should be connected to <SBWD>: For tail of <SBWD> if DONE4 is True <shape> should be direct, otherwise reversed. For head of <SBWD> if DONE5 is True <shape> should be direct, otherwise reversed.
