Detailed Description

Contour with breaks.

Contour with breaks.
For using in the multiline MbMultiline.
Contains breaks MbBreak, visible parts - contours MbContour.
When using in a multiline every time when contour is rebuilding in it are updated list of numbers by the number of contour segments Each number indicates the segment number of base curve of multiline. which corresponds to this segment of contour.
If segment of contour is equidistant of base curve segment, then it corresponds to the number of this segment.
If contour is segment of multiline vertices traverse. then it corresponds to the number corresponding the previous segment of the contour.
Breaks in the contour can not be overlapped each other. If in the result of rebuilding a break overlapped on the other break then they are combined.

(

Creation of empty contour.

Creation of empty contour without segments.

Member Function Documentation

Transform()

void MbContourWithBreaks::Transform ( const MbMatrix &  matr, MbRegTransform *  iReg = nullptr, const MbSurface *  newSurface = nullptr  )

overridevirtual

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.

Parameters

[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.

Reimplemented from MbContour.

Move()

void MbContourWithBreaks::Move ( const MbVector &  to, MbRegTransform *  iReg = nullptr, const MbSurface *  newSurface = nullptr  )

overridevirtual

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.

Parameters

[in]	to	- Translation vector.
[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.

Reimplemented from MbContour.

Rotate()

void MbContourWithBreaks::Rotate ( const MbCartPoint &  pnt, const MbDirection &  angle, MbRegTransform *  iReg = nullptr, const MbSurface *  newSurface = nullptr  )

overridevirtual

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.

Parameters

[in]	pnt	- Fixed point.
[in]	angle	- The rotation angle.
[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.

Reimplemented from MbContour.

Duplicate()

MbPlaneItem& MbContourWithBreaks::Duplicate ( MbRegDuplicate *  iReg = nullptr ) const

overridevirtual

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.

Parameters

[in]

iReg

- Registrator.

Returns

Copy of the object.
