package IGESDimen
---Purpose : This package represents Entities applied to Dimensions
-- ie. Annotation Entities and attached Properties and
-- Associativities.

is
class CenterLine;
-- Type 106, Form 20-21
---Purpose : Is an entity appearing as crosshairs or as a
-- construction between 2 positions
class Section;
-- Type 106, Form 31-38
---Purpose : Contains information to display sectioned sides
class WitnessLine;
-- Type 106, Form 40
---Purpose : Contains one or more straight line segments associated
-- with drafting entities of various types
class AngularDimension;
-- Type 202, Form 0
---Purpose : Used to dimension angles
class CurveDimension;
-- Type 204, Form 0
---Purpose : Used to dimension curves
class DiameterDimension;
-- Type 206, Form 0
---Purpose : Used for dimensioning diameters
class FlagNote;
-- Type 208, Form 0
---Purpose : Is label information formatted in different ways
class GeneralLabel;
-- Type 210, Form 0
---Purpose : Used for general labeling with leaders
class GeneralNote;
-- Type 212, Form 0-8, 100-102, 105
---Purpose : Used for formatting boxed text in different ways
class NewGeneralNote;
-- Type 213, Form 0
---Purpose : Further attributes for formatting text strings
class LeaderArrow;
-- Type 214, Form 1-12
---Purpose : Consists of one or more line segments except when
-- leader is part of an angular dimension, with links to
-- presumed text item
class LinearDimension;
-- Type 216, Form 0
---Purpose : Used for linear dimensioning
class OrdinateDimension;
-- Type 218, Form 0, 1
---Purpose : The ordinate dimension entity is used to
-- indicate dimensions from a common base line.
-- Dimensioning is only permitted along the XT
-- or YT axis.
class PointDimension;
-- Type 220
---Purpose : A Point Dimension Entity consists of a leader, text, and
-- an optional circle or hexagon enclosing the text
class RadiusDimension;
-- Type 222, Form 0, 1
---Purpose : A Radius Dimension Entity consists of a General Note, a
-- leader, and an arc center point. A second form of this
-- entity accounts for the occasional need to have two
-- leader entities referenced.
class GeneralSymbol;
-- Type 228, Form 0
---Purpose : A General Symbol entity consists of zero or one(Form 0)
-- or one(all other forms), one or more geometry entities
-- which define a symbol, and zero, one or more associated
-- leaders.
class SectionedArea;
-- Type 230
---Purpose : A sectioned area is a portion of a design which is to be
-- filled with a pattern of lines.
class DimensionedGeometry;
-- Type 402, Form 13
---Purpose : This associativity links a dimension entity with the
-- geometry entities it is dimensioning.
-- This entity has been replaced by the new form of
-- Dimensioned Geometry Associativity Entity (Type 402,
-- Form 21) and should no longer be used by preprocessors.
class NewDimensionedGeometry;
-- Type 402, Form 21
---Purpose : This Associativity links a dimension entity with the
-- geometry entities it is dimensioning, so that later,
-- in the receiving database, the dimension can be
-- automatically recalculated and redrawn should the
-- geometry be changed.
class DimensionUnits;
-- Type 406, Form 28
---Purpose : The Dimension Units Property describes the units and
-- formatting details of the nominal value of a dimension.
class DimensionTolerance;
-- Type 406, Form 29
---Purpose : The Dimension Tolerance Property provides tolerance
-- information for a dimension. This information can be used
-- by the receiving system to regenerate the dimension.
class DimensionDisplayData;
-- Type 406, Form 30
---Purpose : The Dimensional Display Data Property is optional but when
-- present must be referenced by a dimension entity. The
-- information it contains could be extracted from the text,
-- leader and witness line data with difficulty.
class BasicDimension;
-- Type 406, Form 31
---Purpose : The basic Dimension Property indicates that the referencing
-- dimension entity is to be displayed with a box around text.
-- Tools for Entities --
