class UnionFaces from BlockFix

uses

    Face from TopoDS,
    Shape from TopoDS

is

    Create returns UnionFaces from BlockFix;
    	---Purpose: Empty constructor

    GetTolerance(me: in out) returns Real;
    	---Purpose: Returns modifiable tolerance
	---C++: return&

    Perform (me: in out; Shape: Shape from TopoDS) returns Shape from TopoDS;
    	---Purpose: Performs the unification of the fsces
	--          whith the same geometry

    IsSameDomain(me; aFace      : Face from TopoDS;
    	    	     aChekedFace: Face from TopoDS)
    returns Boolean is virtual;
    	---Purpose: Returns true is surfaces have same geometrically domain
	--          with given tolerance

    MovePCurves(me; aTarget: in out Face from TopoDS;
    	    	    aSource:        Face from TopoDS)
    is virtual;
    	---Purpose: Creates pcurves on aTarget face for each edge from
	--          aSource one.
