22 * \brief Feature for creation of a new constraint splitting object. Entities for split:
23 * - Linear segment by point(s) on this line
24 * - Arc by point(s) on this arc
25 * - Circle by at least 2 split-points on this circle
27 * The following constraints will be applied after split to keep the divided segments geometry:
28 * - Coincident constraints for both parts of created segments in the point of splitting
29 * - For linear segments parallel, for circles
\96 tangent constraint, for arc
\96 tangent and equal
30 * constraints. In case of three segments in result two couple of constraints are created
31 * - parallel and equal constraints: the first is between 1st and middle entity, the second is
32 * between 1st and 3rd.
33 * - tangency constraints: the first between 1st and 2nd, the second between 2nd and 3rd.
34 * - Constraints assigned to the feature before split operation are assigned after using rules:
35 * - Coincident constraints are assigned to the segment where they belong to. Segment of split
36 * has only a coincidence to the neighbor segment. All constraints used in the splitting of
37 * this segment are moved to point of neighbor segment. If constraint was initially built
38 * to the point of splitting segment, it stays for this point.
39 * - Geometrical and dimensional constraints are assigned to one of result segment, not the
40 * selected for split. In case of 3 result segments, this will be the segment nearest to the
41 * start point of arc/line.
42 * - Replication constraint used split feature will be deleted in the same way as it is deleted
43 * by any of entity delete in sketch which is used in this constraint.
45 * This constraint has three attributes:
46 * SketchPlugin_Constraint::VALUE() contains reference object to be splitted
47 * SketchPlugin_Constraint::ENTITY_A() and SketchPlugin_Constraint::ENTITY_B() for the points of split;
