Next version.

Implementation of the algorithm for replacing faces in shape with new faces based on other surfaces - BRepOffsetAPI_PatchFaces.

The algorithm runs the steps similar to 3d Offset algorithm for Join type Intersection (intersection of the faces with neighbors for trimming of the faces by the adjacent faces).

-In an XDE document, custom notes are managed by the class *XCAFDoc_NotesTool*. This is done with the same principles as for ShapeTool with Shapes, and with the same capability of having a tool on the Main Label, or on any sub-label. The Property itself is defined as sub-classes of an *XCAFDoc_Note* abstract class, which is a sub-class of *TDF_Attribute* one. 
+XDE can read and write GD&T assigned to shapes or their subparts (down to the level of faces and edges) to and from STEP formats. 
 
-Custom notes are stored in a child of the *XCAFDoc_NotesTool* label: it is at label 0.1.9.1. Each note then corresponds to a dedicated label. A note may be attached to a document item identified by a label, a sub-shape identified by integer index or an attribute identified by GUID. Annotations are stored in a child of the *XCAFDoc_NotesTool* label: it is at label 0.1.9.2.
+In an XDE document, GD&T are managed by the class *XCAFDoc_DimTolTool*. It works basing on the same principles as ShapeTool works with Shapes. This tool can be provided on the Main Label or on any sub-label. The GD&T entities themselves are defined as the following sub-classes of *TDF_Attribute*:
+  * *XCAFDoc_Dimension* - for dimensions;
+  * *XCAFDoc_GeomTolerance* - for geometric tolerances;
+  * *XCAFDoc_Datum* - for geometric tolerance Datums.
+A GD&T type is identified by the attributes listed above, i.e. *XCAFDoc_DimTolTool* methods working with particular entity types check 
+for presence of the corresponding attributes in passed labels. One can use methods of *XCAFDoc_DimTolTool* beginning with 'Is' for this purpose.
+ 
+GD&T entities are stored in a child of the starting document label 0.1.4. 
+Each GD&T entity then corresponds to the dedicated label, the property itself is one of access classes:
+  * *XCAFDimTolObject_DimensionObject* - for dimensions;
+  * *XCAFDimTolObject_GeomToleranceObject* - for geometric tolerances;
+  * *XCAFDimTolObject_DatumObject* - for geometric tolerance Datums.
+
+GD&Ts and Shapes are related to by Graph Nodes. 
+
+These definitions are common to various exchange formats, at least for STEP. 
+
+@subsubsection occt_xde_2_7_1 Initialization
+To query, edit, or initialize a Document to handle GD&Ts of XCAF, use: 
+~~~~~
+Handle(XCAFDoc_DimTolTool) myDimTolTool = 
+XCAFDoc_DocumentTool::DimTolTool(Doc->Main()); 
+~~~~~
+This call can be used at any time. When it is used for the first time, a relevant structure is added to the document. This definition is used for all later GD&T calls and is not repeated for them. 
+
+@subsubsection occt_xde_2_7_2 Adding a GD&T
+*XCAFDoc_DimTolTool* provides methods to create GD&T 'empty' entities:
+  * *AddDimension* - for a new dimension;
+  * *AddGeomTolerance* - for a new geometric tolerance;
+  * *AddDatum* - for a new geometric tolerance datum.
+
+All methods create a sub-label for the corresponding GD&T entity of the tool master label and attach an attribute specific for the
+created entity.
+
+Here is an example of adding a new dimension:
+~~~~~
+TDF_Label aDimLabel = myDimTolTool->AddDimension();
+if (!aDimLabel.IsNull())
+{
+  // error processing
+}
+~~~~~
+A similar approach can be used for other GD&T types.
+
+@subsubsection occt_xde_2_7_3 Editing a GD&T
+A newly added GD&T entity is empty. To set its data a corresponding access object should be used as it is demonstrated
+below, where the dimension becomes the linear distance between two points.
+~~~~~
+Handle(XCAFDoc_Dimension) aDimAttr;
+aDimLabel.FindAttribute(XCAFDoc_Dimension::GetID(), aDimAttr);
+if (!aDimAttr.IsNull())
+{
+  Handle(XCAFDimTolObjects_DimensionObject) aDimObject = aDimAttr->GetObject();
+  // set dimension data
+  aDimObject->SetType(XCAFDimTolObjects_DimensionType_Location_LinearDistance);
+  aDimObject->SetPoint(thePnt1);  // the first reference point
+  aDimObject->SetPoint2(thePnt2); // the second reference point
+  aDimObject->SetValue(theValue); // the distance value
+  //...
+  aDimAttr->SetObject(aDimObject);
+}
+~~~~~
+A similar approach can be used for other GD&T types.
+
+@subsubsection occt_xde_2_7_4 Linking GD&Ts
+To link a GD&T entity with other OCAF labels (e.g. representing shapes) one should use the following methods:
+  * *SetDimension* - for dimensions;
+  * *SetGeomTolerance* - for geometric tolerances;
+  * SetDatum - for geometric tolerance datums.
+
+These methods can take a single label or a sequence of labels. All previous links will be removed.
+
+The example below demonstrates linking of a dimension to sequences of shape labels:
+~~~~~
+TDF_LabelSequence aShapes1, aShapes2;
+aShapes1.Append(aShape11);
+//...
+aShapes2.Append(aShape21);
+//...
+aDGTTool->SetDimension(aShapes1, aShapes2, aDimLabel);
+~~~~~
+

+
+@subsubsection occt_xde_2_7_5 Finding GD&Ts and reference shapes
+
+*XCAFDimTolObjects_Tool* class provides basic capabilities for searching GD&Ts linked to shapes.
+Using the tool one can get sequences of dimensions, geometric tolerances and datums linked with a shape. A series of related datums is also returned for geometric tolerances.
+
+To get reference shapes for a GD&T entity one can use *GetRefShapeLabel* from *XCAFDoc_DimTolTool*.
+
+*XCAFDoc_DimTolTool* provides methods to get lists of all dimensions, geometric tolerances and datums.
+
+@subsubsection occt_xde_2_7_6 Storing custom data
+Every GD&T entity in XDE is represented as a label with attached attribute identifying entity type. All specific data is
+stored in sub-labels in standard OCAF attributes, such as *TDataStd_Integer*, *TDataStd_IntegerArray*, *TDataStd_RealArray* and so on.
+Sub-label tags are reserved for internal use and cannot be used for storing custom data. The following tag ranges are reserved for
+GD&T entities:
+  * 1 - 17 - for dimensions;
+  * 1 - 17 - for geometric tolerances;
+  * 1 - 19 - for datums.
+Custom data can be stored in labels with tags beyond the ranges listed above.

+@subsection occt_xde_2_8 Clipping planes
+
+In an XDE document, Clipping planes are managed by the class *XCAFDoc_ClippingPlaneTool*. It works basing on the same principles as ShapeTool works with Shapes. This tool can be provided on the Main Label or on any sub-label. Clipping planes are stored in a child of the starting document label 0.1.8, where planes themselves are defined as *TDataXtd_Plane* attribute. *TDataStd_Name* attribute is used for naming.
+
+To query, edit, or initialize a Document to handle clipping planes of XCAF, use: 
+~~~~~
+Handle(XCAFDoc_ClippingPlaneTool) myClipPlaneTool = 
+XCAFDoc_DocumentTool::ClippingPlaneTool(Doc->Main()); 
+~~~~~
+This call can be used at any time. When it is used for the first time, a relevant structure is added to the document. 
+
+To add a clipping plane use one of overloaded methods *AddClippingPlane*, e.g.:
+~~~~~
+gp_Pln aPln = ...
+Standard_Boolean aCapping = ...
+TDF_Label aClipPlnLbl = myClipPlaneTool->AddClippingPlane(aPln, "Name of plane", aCapping);
+if (aClipPlnLbl.IsNull())
+{
+  // error processing

+
+To remove a plane use *RemoveClippingPlane* method, e.g.:
+~~~~~
+if (!myClipPlaneTool->RemoveClippingPlane(aClipPlnLbl))
+{
+  // not removed
+}
+~~~~~
+The plane will not be removed if it is referenced in at least one view.
+
+To change clipping plane and its name use *UpdateClippingPlane* method, e.g.:
+~~~~~
+gp_Pln aPln = ...
+myClipPlaneTool->UpdateClippingPlane(aClipPlnLbl, aPln, "New name of plane");
+~~~~~
+
+Capping property can be changed using *SetCapping* method, e.g.:
+~~~~~
+Standard_Boolean aCapping = ...
+myClipPlaneTool->SetCapping(aClipPlnLbl, aCapping);
+~~~~~
+
+*XCAFDoc_ClippingPlaneTool* can be used to get all clipping plane labels and to check if a label belongs to the ClippingPlane table, e.g.:

+
+In an XDE document, Views are managed by the class *XCAFDoc_ViewTool*. It works basing on the same principles as ShapeTool works with Shapes. This tool can be provided on the Main Label or on any sub-label. Views are stored in a child of the starting document label 0.1.7, where a view itself is defined as *XCAFDoc_View* sub-class of *TDF_Attribute*. Views and selected shapes, clipping planes, GD&Ts and notes are related to by Graph Nodes.

+~~~~~
+This call can be used at any time. When it is used for the first time, a relevant structure is added to the document. 
+
+To add a view use *AddView* method and an access *XCAFView_Object* object to set camera parameters, e.g.:
+~~~~~
+TDF_Label aViewLbl = myViewTool->AddView();
+if (aViewLbl.IsNull())
+{
+  // error processing

+  * *GetRefGDTLabel* - returns a sequence of associated GDT labels;
+  * *GetRefClippingPlaneLabel* - returns a sequence of associated clipping plane labels;
+  * *GetRefNoteLabel* - returns a sequence of associated note labels;
+  * *GetRefAnnotationLabel* - returns a sequence of associated annotated labels.
+
+And vice versa, to get views that display a particular clipping plane, GD&T or note use the following methods:
+  * *GetViewLabelsForShape* - returns a sequence of associated view labels for a shape;
+  * *GetViewLabelsForGDT* - returns a sequence of associated view labels for a GD&T;
+  * *GetViewLabelsForClippingPlane* - returns a sequence of associated view labels for a clipping plane;

+@subsection occt_xde_2_10 Custom notes
+
+In an XDE document, custom notes are managed by the class *XCAFDoc_NotesTool*. It works basing on the same principles as ShapeTool works with Shapes. This tool can be provided on the Main Label or on any sub-label. The Property itself is defined as sub-class of *XCAFDoc_Note* abstract class, which is a sub-class of *TDF_Attribute* one. 
+
+Custom notes are stored in a child of the *XCAFDoc_NotesTool* label, at label 0.1.9.1. Each note then corresponds to a dedicated label. A note may be attached to a document item identified by a label, a sub-shape identified by integer index or an attribute identified by GUID. Annotations are stored in a child of the *XCAFDoc_NotesTool* label, at label 0.1.9.2.
 Notes binding is done through *XCAFDoc_GraphNode* attribute.

 Note that saving and restoring the document itself are standard OCAF operations. As the various previously described definitions enter into this frame, they will not be explained any further. 
 The same can be said for Viewing: presentations can be defined from Shapes and Colors. 
 
 There are several important points to consider: 
   * Previously defined Readers and Writers for dealing with Shapes only, whether Standard or Advanced, remain unchanged in their form and in their dependencies. In addition, functions other than mapping are also unchanged.
-  * XDE provides mapping with data other than Shapes. Names, Colors, Layers, Validation Properties (Centroid, Volume, Area), and Assembly Structure are hierarchic with rigid motion.
+  * XDE provides mapping with data other than Shapes. Names, Colors, Layers, GD&T, Clipping planes, Views, Validation Properties (Centroid, Volume, Area), and Assembly Structure are hierarchic with rigid motion. Currently, Clipping planes and Views writing supported for XBF format only.
   * XDE mapping is relevant for use within the Advanced level of Data Exchanges, rather than Standard ones, because a higher level of information is better suited to a higher quality of shapes. In addition, this allows to avoid the multiplicity of combinations between various options. Note that this choice is not one of architecture but of practical usage and packaging.
   * Reader and Writer classes for XDE are generally used like those for Shapes. However, their use is adapted to manage a Document rather than a Shape.
   
 The packages to manage this are *IGESCAFControl* for IGES, and *STEPCAFControl* for STEP.

 There are several ways of exploiting XDE data from an application, you can: 
  1. Get the data relevant for the application by mapping XDE/Appli, then discard the XDE data once it has been used.
  2. Create a reference from the Application Document to the XDE Document, to have its data available as external data.
  3. Embed XDE data inside the Application Document (see the following section for details).
  4. Directly exploit XDE data such as when using file checkers.

 To have XCAF data elsewhere than under label 0.1, you use the DocLabel of XDE. The method DocLabel from XCAFDoc_DocumentTool determines the relevant Label for XCAF. However, note that the default is 0.1. 
 
 In addition, as XDE data is defined and managed in a modular way, you can consider exclusively Assembly Structure, only Colors, and so on.
