Class implements interface representing tool for discrete model building.
The following statuses should be used by default: Message_Done1 - model has been successfully built. Message_Fail1 - empty shape. Message_Fail2 - model has not been build due to unexpected reason.

Class implements functionality of model healer tool.
Iterates over model's faces and checks consistency of their wires, i.e.whether wires are closed and do not contain self - intersections.
In case if wire contains disconnected parts, ends of adjacent edges forming the gaps are connected in parametric space forcibly.
The notion of this operation is to create correct discrete model defined relatively parametric space of target face taking into account connectivity and tolerances of 3D space only. This means that there are no specific computations are made for the sake of determination of U and V tolerance.
Registers intersections on edges forming the face's shape and tries to amplify discrete representation by decreasing of deflection for the target edge. Checks can be performed in parallel mode.
