pure virtual 
Create a copy.
Create a copy of the object using the registrator. The registrator is used for preventing multiple copying of an object. If the object contains references to other objects, then the included objects are copied too. It is allowed not to pass the registrator to a function. Then the new copy of the object will be created. It is allowed not to use the registrator while copying a single object or a set of disconnected objects. The registrator must be used to copy several correlated objects successively. It is possible that the objects' connection means that the objects contain references to the common objects. Then, while copying without using the registrator, one can get a set of copies which contain references to the different copies of a single included object, what leads to loss of connection between the copies.
[in]  iReg   Registrator. 
Implemented in MbRegion, MbMultiline, MbTrimmedCurve, MbReparamCurve, MbProjCurve, MbPolyline, MbPointCurve, MbOffsetCurve, MbNurbs, MbLineSegment, MbLine, MbHermit, MbCubicSpline, MbCosinusoid, MbContourWithBreaks, MbContour, MbCharacterCurve, MbBezier, and MbArc.

pure virtual 
Transform according to the matrix.
Transform the initial object according to the matrix using the registrator. If the object contains references to the other geometric objects, then the nested objects are transformed according to the matrix. The registrator is used for preventing multiple transformation of the object. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested objects, since it is not ruled out that several objects from the set contain references to one or several common objects subject to transformation.
[in]  matr   A transformation matrix. 
[in]  iReg   Registrator. 
[in]  surface   New base surface of object provided that 'matr' is a transformation matrix from the old surface to a new one. For transformation of projection curve. It isn't considered if the surface is planar.

pure virtual 
Translate along a vector.
Translate a geometric object along the vector using the registrator. If the object contains references to the other objects, then the translation operation is applied to the nested objects. The registrator is used for preventing multiple transformation of the object. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested objects, since it is not ruled out that several objects from the set contain references to one or several common objects subject to translation.

pure virtual 
Rotate about a point.
Rotate an object about a point by the given angle using the registrator. If the object contains references to the other geometric objects, then the rotation operation is applied to the nested objects too. The registrator is used for preventing multiple transformation of the object. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested objects, since it is not ruled out that several objects from the set contain references to one or several common objects subject to rotation.

Object registration.
Object registration for preventing its multiple writing. Other objects may contain a pointer to the given object. The function sets a flag that allow to write the object once and to use the references to the recorded instance in the other records. Reading is performed once too, in other cases of reading the address of the already read object is used.
