For a complete surface of revolution the parametric range is 0 <= U <= 2*PI. – The parametric range for V is defined with the revolved curve. The origin of the U parametrization is given by the position of the revolved curve (reference). The direction of the revolution axis defines the positive sense of rotation (trigonometric sense) corresponding to the increasing of the parametric value U. The derivatives are always defined for the u direction. For the v direction the definition of the derivatives depends on the degree of continuity of the referenced curve. Curve and Axis are coplanar.

AIS  Application Interactive Services provide the means to create links between an application GUI viewer and the packages which are used to manage selection and presentation. The tools AIS defined in order to do this include different sorts of entities: both the selectable viewable objects themselves and the context and attribute managers to define their selection and display. To orient the user as he works in a modeling environment, views and selections must be comprehensible. There must be several different sorts of selectable and viewable object defined. These must also be interactive, that is, connecting graphic representation and the underlying reference geometry. These entities are called Interactive Objects, and are divided into four types: 
AIS_AngleDimension  Angle dimension. Can be constructed: 
AIS_AttributeFilter  Selects Interactive Objects, which have the desired width or color. The filter questions each Interactive Object in local context to determine whether it has an nonnull owner, and if so, whether it has the required color and width attributes. If the object returns true in each case, it is kept. If not, it is rejected. This filter is used only in an open local context. In the Collector viewer, you can only locate Interactive Objects, which answer positively to the filters, which are in position when a local context is open 
AIS_Axis  Locates the x, y and z axes in an Interactive Object. These are used to orient it correctly in presentations from different viewpoints, or to construct a revolved shape, for example, from one of the axes. Conversely, an axis can be created to build a revolved shape and then situated relative to one of the axes of the view

AIS_Chamf3dDimension  A framework to define display of 3D chamfers. A chamfer is displayed with arrows and text. The text gives the length of the chamfer if it is a symmetrical chamfer, or the angle if it is not 
AIS_Circle  Constructs circle datums to be used in construction of composite shapes 
AIS_ColoredDrawer  Customizable properties 
AIS_ColoredShape  Presentation of the shape with customizable subshapes properties 
AIS_ConcentricRelation  A framework to define a constraint by a relation of concentricity between two or more interactive datums. The display of this constraint is also defined. A plane is used to create an axis along which the relation of concentricity can be extended 
AIS_ConnectedInteractive  Creates an arbitrary located instance of another Interactive Object, which serves as a reference. This allows you to use the Connected Interactive Object without having to recalculate presentation, selection or graphic structure. These are deduced from your reference object. The relation between the connected interactive object and its source is generally one of geometric transformation. AIS_ConnectedInteractive class supports selection mode 0 for any InteractiveObject and all standard modes if its reference based on AIS_Shape. Descendants may redefine ComputeSelection() though. Also ConnectedInteractive will handle HLR if its reference based on AIS_Shape

AIS_DiameterDimension  Diameter dimension. Can be constructued: 
AIS_Dimension  AIS_Dimension is a base class for 2D presentations of linear (length, diameter, radius) and angular dimensions 
AIS_DimensionOwner  The owner is the entity which makes it possible to link the sensitive primitives and the reference shapes that you want to detect. It stocks the various pieces of information which make it possible to find objects. An owner has a priority which you can modulate, so as to make one entity more selectable than another. You might want to make edges more selectable than faces, for example. In that case, you could attribute sa higher priority to the one compared to the other. An edge, could have priority 5, for example, and a face, priority 4. The default priority is 5 
AIS_EllipseRadiusDimension  Computes geometry ( basis curve and plane of dimension) for input shape aShape from TopoDS Root class for MinRadiusDimension and MaxRadiusDimension 
AIS_EqualDistanceRelation  A framework to display equivalent distances between shapes and a given plane. The distance is the length of a projection from the shape to the plane. These distances are used to compare shapes by this vector alone 
AIS_EqualRadiusRelation  
AIS_ExclusionFilter  A framework to reject or to accept only objects of given types and/or signatures. Objects are stored, and the stored objects  along with the flag settings  are used to define the filter. Objects to be filtered are compared with the stored objects added to the filter, and are accepted or rejected according to the exclusion flag setting 
AIS_FixRelation  Constructs and manages a constraint by a fixed relation between two or more interactive datums. This constraint is represented by a wire from a shape  point, vertex, or edge  in the first datum and a corresponding shape in the second. Warning: This relation is not bound with any kind of parametric constraint : it represents the "status" of an parametric object 
AIS_GlobalStatus  Stores information about objects in graphic context: 
AIS_GraphicTool  
AIS_IdenticRelation  Constructs a constraint by a relation of identity between two or more datums figuring in shape Interactive Objects 
AIS_IndexedDataMapNodeOfIndexedDataMapOfOwnerPrs  
AIS_IndexedDataMapOfOwnerPrs  
AIS_InteractiveContext  The Interactive Context allows you to manage graphic behavior and selection of Interactive Objects in one or more viewers. Class methods make this highly transparent. It is essential to remember that an Interactive Object which is already known by the Interactive Context must be modified using Context methods. You can only directly call the methods available for an Interactive Object if it has not been loaded into an Interactive Context. You must distinguish two states in the Interactive Context: 
AIS_InteractiveObject  Defines a class of objects with display and selection services. Entities which are visualized and selected are Interactive Objects. You can make use of classes of standard Interactive Objects for which all necessary methods have already been programmed, or you can implement your own classes of Interactive Objects. Specific attributes of entities such as arrow aspect for dimensions must be loaded in a Drawer. This Drawer is then applied to the Interactive Object in view. There are four types of Interactive Object in AIS: the construction element or Datum, the Relation, which includes both dimensions and constraints, the Object, and finally, when the object is of an unknown type, the None type. Inside these categories, a signature, or index, provides the possibility of additional characterization. By default, the Interactive Object has a None type and a signature of 0. If you want to give a particular type and signature to your interactive object, you must redefine the methods, Signature and Type. Warning In the case of attribute methods, methods for standard attributes are virtual. They must be redefined by the inheriting classes. Setcolor for a point and Setcolor for a plane, for example, do not affect the same attributes in the Drawer 
AIS_LengthDimension  Length dimension. Can be constructued: 
AIS_Line  Constructs line datums to be used in construction of composite shapes 
AIS_ListIteratorOfListOfInteractive  
AIS_ListNodeOfListOfInteractive

AIS_MaxRadiusDimension  Ellipse Max radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset)) 
AIS_MidPointRelation  Presentation of equal distance to point myMidPoint 
AIS_MinRadiusDimension  – Ellipse Min radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset)) 
AIS_MultipleConnectedInteractive  Defines an Interactive Object by gathering together several object presentations. This is done through a list of interactive objects. These can also be Connected objects. That way memorycostly calculations of presentation are avoided 
AIS_OffsetDimension  A framework to display dimensions of offsets. The relation between the offset and the basis shape is indicated. This relation is displayed with arrows and text. The text gives the dsitance between the offset and the basis shape 
AIS_ParallelRelation  A framework to display constraints of parallelism between two or more Interactive Objects. These entities can be faces or edges 
AIS_PerpendicularRelation  A framework to display constraints of perpendicularity between two or more interactive datums. These datums can be edges or faces 
AIS_Plane  Constructs plane datums to be used in construction of composite shapes 
AIS_PlaneTrihedron  To construct a selectable 2d axis system in a 3d drawing. This can be placed anywhere in the 3d system, and provides a coordinate system for drawing curves and shapes in a plane. There are 3 selection modes: 
AIS_Point  Constructs point datums to be used in construction of composite shapes. The datum is displayed as the plus marker + 
AIS_PointCloud  Interactive object for set of points. The presentation supports two display modes: 
AIS_RadiusDimension  Radius dimension. Can be constructued: 
AIS_Relation  One of the four types of interactive object in AIS,comprising dimensions and constraints. Serves as the abstract class for the seven relation classes as well as the seven dimension classes. The statuses available for relations between shapes are as follows: 
AIS_Selection  
AIS_SequenceNodeOfSequenceOfDimension  
AIS_SequenceNodeOfSequenceOfInteractive  
AIS_SequenceOfDimension  
AIS_SequenceOfInteractive  
AIS_Shape  A framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes  vertices, edges, faces etc  in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient  both HLR and nonHLR  of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object 
AIS_SignatureFilter  Selects Interactive Objects through their signatures and types. The signature provides an additional characterization of an object's type, and takes the form of an index. The filter questions each Interactive Object in local context to determine whether it has an nonnull owner, and if so, whether it has the desired signature. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is only used in an open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning Some signatures have already been used by standard objects delivered in AIS. These include: 
AIS_StdMapNodeOfMapOfInteractive  
AIS_SymmetricRelation  A framework to display constraints of symmetricity between two or more datum Interactive Objects. A plane serves as the axis of symmetry between the shapes of which the datums are parts 
AIS_TangentRelation  A framework to display tangency constraints between two or more Interactive Objects of the datum type. The datums are normally faces or edges 
AIS_TextLabel  Presentation of the text 
AIS_TexturedShape  This class allows to map textures on shapes. Presentations modes AIS_WireFrame (0) and AIS_Shaded (1) behave in the same manner as in AIS_Shape, whilst new modes 2 (bounding box) and 3 (texture mapping) extends it functionality 
AIS_Triangulation  Interactive object that draws data from Poly_Triangulation, optionally with colors associated with each triangulation vertex. For maximum efficiency colors are represented as 32bit integers instead of classic Quantity_Color values. Interactive selection of triangles and vertices is not yet implemented 
AIS_Trihedron  Create a selectable trihedron there are 4 modes of selection : mode = 0 to select triedron ,priority = 1 mode = 1 to select its origine ,priority = 5 mode = 2 to select its axis ,priority = 3 mode = 3 to select its planes ,priority = 2 a trihedron has 1 origine,3 axes,3 planes. Warning For the presentation of trihedra, the default unit of length is the millimetre, and the default value for the representation of the axes is 100. If you modify these dimensions, you must temporarily recover the Drawer. From inside it, you take the aspect in which the values for length are stocked. For trihedra, this is Prs3d_Drawer_FirstAxisAspect. You change the values inside this Aspect and recalculate the presentation. If you want to use extended selection modes, different than 0, you should take care of removing of the shapes from the interactive context that has been computed for selection; it might be necessary when you change selection mode. You can use methods Axis, Point, Plane to retrieve the shapes 
AIS_TypeFilter  Selects Interactive Objects through their types. The filter questions each Interactive Object in local context to determine whether it has an nonnull owner, and if so, whether it is of the desired type. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. A filter for type specifies a choice of type out of a range at any level enumerated for type or kind. The choice could be for kind of interactive object, of dimension, of unit, or type of axis, plane or attribute. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is used in both Neutral Point and open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning When you close a local context, all temporary interactive objects are deleted, all selection modes concerning the context are cancelled, and all content filters are emptied

BRepFeat  BRepFeat is necessary for the creation and manipulation of both form and mechanical features in a Boundary Representation framework. Form features can be depressions or protrusions and include the following types: 
BRepFeat_Builder  Provides a basic tool to implement features topological operations. The main goal of the algorithm is to perform the result of the operation according to the kept parts of the tool. Input data: a) DS; b) The kept parts of the tool; If the map of the kept parts of the tool is not filled boolean operation of the given type will be performed; c) Operation required. Steps: a) Fill myShapes, myRemoved maps; b) Rebuild edges and faces; c) Build images of the object; d) Build the result of the operation. Result: Result shape of the operation required 
BRepFeat_Form  Provides general functions to build form features. Form features can be depressions or protrusions and include the following types: 
BRepFeat_Gluer  One of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which  or up to which  matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. Glueing uses wires or edges of a face in the basis shape. These are to become a part of the feature. They are first cut out and then projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion features can be constructed 
BRepFeat_MakeCylindricalHole  Provides a tool to make cylindrical holes on a shape 
BRepFeat_MakeDPrism  Describes functions to build draft prism topologies from basis shape surfaces. These can be depressions or protrusions. The semantics of draft prism feature creation is based on the construction of shapes: 
BRepFeat_MakeLinearForm  Builds a rib or a groove along a developable, planar surface. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be symmetrical  on one side of the contour  or dissymmetrical  on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however, in case of mechanical features. Here they include extrusion: 
BRepFeat_MakePipe  Constructs compound shapes with pipe features. These can be depressions or protrusions. The semantics of pipe feature creation is based on the construction of shapes: 
BRepFeat_MakePrism  Describes functions to build prism features. These can be depressions or protrusions. The semantics of prism feature creation is based on the construction of shapes: 
BRepFeat_MakeRevol  Describes functions to build revolved shells from basis shapes 
BRepFeat_MakeRevolutionForm  MakeRevolutionForm Generates a surface of revolution in the feature as it slides along a revolved face in the basis shape. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral  on one side of the contour  or bilateral  on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion: 
BRepFeat_RibSlot  Provides functions to build mechanical features. Mechanical features include ribs  protrusions and grooves (or slots)  depressions along planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral  on one side of the contour  or bilateral  on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion: 
BRepFeat_SplitShape  One of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which  or up to which  matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. In BRepFeat, the semantics of local operations define features constructed from a contour or a part of the basis shape referred to as the tool. In a SplitShape object, wires or edges of a face in the basis shape to be used as a part of the feature are cut out and projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion or depression features can be constructed

A BSplineCurveKnotSplitting object provides a framework for:

GeomConvert_BSplineSurfaceKnotSplitting  An algorithm to determine isoparametric curves along which a BSpline surface should be split in order to obtain patches of the same continuity. The continuity order is given at the construction time. It is possible to compute the surface patches corresponding to the splitting with the method of package SplitBSplineSurface. For a Bspline surface the discontinuities are localised at the knot values. Between two knots values the Bspline is infinitely continuously differentiable. For each parametric direction at a knot of range index the continuity in this direction is equal to : Degree  Mult (Index) where Degree is the degree of the basis Bspline functions and Mult the multiplicity of the knot of range Index in the given direction. If for your computation you need to have Bspline surface with a minima of continuity it can be interesting to know between which knot values, a Bspline patch, has a continuity of given order. This algorithm computes the indexes of the knots where you should split the surface, to obtain patches with a constant continuity given at the construction time. If you just want to compute the local derivatives on the surface you don't need to create the BSpline patches, you can use the functions LocalD1, LocalD2, LocalD3, LocalDN of the class BSplineSurface from package Geom

GProp_PGProps  A framework for computing the global properties of a set of points. A point mass is attached to each point. The global mass of the system is the sum of each individual mass. By default, the point mass is equal to 1 and the mass of a system composed of N points is equal to N. Warning A framework of this sort provides functions to handle sets of points easily. But, like any GProp_GProps object, by using the Add function, it can theoretically bring together the computed global properties and those of a system more complex than a set of points . The mass of each point and the density of each component of the composed system must be coherent. Note that this coherence cannot be checked.

These axes are the principal axes of inertia. Their origin is coincident with the center of mass of the system. The associated moments are called the principal moments of inertia. This sort of presentation object is created, filled and returned by the function PrincipalProperties for any GProp_GProps object, and can be queried to access the result. Note: The system whose principal properties of inertia are returned by this framework is referred to as the current system. The current system, however, is retained neither by this presentation framework nor by the GProp_GProps object which activates it

HLRAlgo  In order to have the precision required in industrial design, drawings need to offer the possibility of removing lines, which are hidden in a given projection. To do this, the Hidden Line Removal component provides two algorithms: HLRBRep_Algo and HLRBRep_PolyAlgo. These algorithms remove or indicate lines hidden by surfaces. For a given projection, they calculate a set of lines characteristic of the object being represented. They are also used in conjunction with extraction utilities, which reconstruct a new, simplified shape from a selection of calculation results. This new shape is made up of edges, which represent the lines of the visualized shape in a plane. This plane is the projection plane. HLRBRep_Algo takes into account the shape itself. HLRBRep_PolyAlgo works with a polyhedral simplification of the shape. When you use HLRBRep_Algo, you obtain an exact result, whereas, when you use HLRBRep_PolyAlgo, you reduce computation time but obtain polygonal segments

IFSelect_Activator  Defines the general frame for working with a SessionPilot. Each Activator treats a set of Commands. Commands are given as alphanumeric strings. They can be of two main forms : 
IFSelect_AppliedModifiers  This class allows to memorize and access to the modifiers which are to be applied to a file. To each modifier, is bound a list of integers (optionnal) : if this list is absent, the modifier applies to all the file. Else, it applies to the entities designated by these numbers in the produced file

IFSelect_GeneralModifier  This class gives a frame for Actions which modify the effect of a Dispatch, i.e. : By Selections and Dispatches, an original Model can be splitted into one or more "target" Models : these Models contain Entities copied from the original one (that is, a part of it). Basically, these dispatched Entities are copied as identical to their original counterparts. Also the copied Models reproduce the Header of the original one 
IFSelect_GraphCounter  A GraphCounter computes values to be sorted with the help of a Graph. I.E. not from a Signature 
IFSelect_HSeqOfSelection  
IFSelect_IntParam  This class simply allows to access an Integer value through a Handle, as a String can be (by using HString).

Thus, parameters of a Selection or a Dispatch (according its type) can be controlled directly from the ShareOut which contains them 
IFSelect_ListEditor  A ListEditor is an auxiliary operator for Editor/EditForm I.E. it works on parameter values expressed as strings 
IFSelect_ModelCopier  This class performs the Copy operations involved by the description of a ShareOut (evaluated by a ShareOutResult) plus, if there are, the Modifications on the results, with the help of Modifiers.

IFSelect_PacketList  This class gives a simple way to return then consult a list of packets, determined from the content of a Model, by various criteria 
IFSelect_ParamEditor  A ParamEditor gives access for edition to a list of TypedValue (i.e. of Static too) Its definition is made of the TypedValue to edit themselves, and can add some constants, which can then be displayed but not changed (for instance, system name, processor version ...) 
IFSelect_SelectAnyList  A SelectAnyList kind Selection selects a List of an Entity, as well as this Entity contains some. A List contains subentities as one per Item, or several (for instance if an Entity binds couples of subentities, each item is one of these couples). Remark that only Entities are taken into account (neither Reals, nor Strings, etc...) 
IFSelect_SelectAnyType  A SelectAnyType sorts the Entities of which the Type is Kind of a given Type : this Type for Match is specific of each class of SelectAnyType 
IFSelect_SelectBase  SelectBase works directly from an InterfaceModel : it is the first base for other Selections 
IFSelect_SelectCombine  A SelectCombine type Selection defines algebraic operations between results of several Selections It is a deferred class : subclasses will have to define precise what operator is to be applied 
IFSelect_SelectControl  A SelectControl kind Selection works with two input Selections in a dissymmetric way : the Main Input which gives an input list of Entities, to be processed, and the Second Input which gives another list, to be used to filter the main input 
IFSelect_SelectDeduct  A SelectDeduct determines a list of Entities from an Input Selection, by a computation : Output list is not obliged to be a sublist of Input list (for more specific, see SelectExtract for filtered sublists, and SelectExplore for recurcive exploration) 
IFSelect_SelectDiff  A SelectDiff keeps the entities from a Selection, the Main Input, which are not listed by the Second Input 
IFSelect_SelectEntityNumber  A SelectEntityNumber gets in an InterfaceModel (through a Graph), the Entity which has a specified Number (its rank of adding into the Model) : there can be zero (if none) or one. The Number is not directly defined as an Integer, but as a Parameter, which can be externally controled 
IFSelect_SelectErrorEntities  A SelectErrorEntities sorts the Entities which are qualified as "Error" (their Type has not been recognized) during reading a File. This does not concern Entities which are syntactically correct, but with incorrect data (for integrity constraints) 
IFSelect_SelectExplore  A SelectExplore determines from an input list of Entities, a list obtained by a way of exploration. This implies the possibility of recursive exploration : the output list is itself reused as input, etc... Examples : Shared Entities, can be considered at one level (immediate shared) or more, or max level 
IFSelect_SelectExtract  A SelectExtract determines a list of Entities from an Input Selection, as a sublist of the Input Result It works by applying a sort criterium on each Entity of the Input. This criterium can be applied Direct to Pick Items (default case) or Reverse to Remove Item 
IFSelect_SelectFlag  A SelectFlag queries a flag noted in the bitmap of the Graph. The Flag is designated by its Name. Flag Names are defined by Work Session and, as necessary, other functional objects 
IFSelect_SelectIncorrectEntities  A SelectIncorrectEntities sorts the Entities which have been noted as Incorrect in the Graph of the Session (flag "Incorrect") It can find a result only if ComputeCheck has formerly been called on the WorkSession. Else, its result will be empty 
IFSelect_SelectInList  A SelectInList kind Selection selects a List of an Entity, which is composed of single Entities To know the list on which to work, SelectInList has two deferred methods : NbItems (inherited from SelectAnyList) and ListedEntity (which gives an item as an Entity) which must be defined to get a List in an Entity of the required Type (and consider that list is empty if Entity has not required Type) 
IFSelect_SelectIntersection  A SelectIntersection filters the Entities issued from several other Selections as Intersection of results : "AND" operator 
IFSelect_Selection  A Selection allows to define a set of Interface Entities. Entities to be put on an output file should be identified in a way as independant from such or such execution as possible.

IFSelect_SelectionIterator  Defines an Iterator on a list of Selections 
IFSelect_SelectModelEntities  A SelectModelEntities gets all the Entities of an InterfaceModel 
IFSelect_SelectModelRoots  A SelectModelRoots gets all the Root Entities of an InterfaceModel. Remember that a "Root Entity" is defined as having no Sharing Entity (if there is a Loop between Entities, none of them can be a "Root") 
IFSelect_SelectPointed  This type of Selection is intended to describe a direct selection without an explicit criterium, for instance the result of picking viewed entities on a graphic screen 
IFSelect_SelectRange  A SelectRange keeps or rejects a subset of the input set, that is the Entities of which rank in the iteration list is in a given range (for instance form 2nd to 6th, etc...)
