class DrawingWithRotation from IGESDraw inherits IGESEntity
---Purpose: defines IGESDrawingWithRotation, Type <404> Form <1>
-- in package IGESDraw
--
-- Permits rotation, in addition to transformation and
-- scaling, between the view and drawing coordinate systems
uses
HArray1OfIGESEntity from IGESData,
HArray1OfReal from TColStd,
ViewKindEntity from IGESData,
HArray1OfViewKindEntity from IGESDraw,
Pnt2d from gp,
XYZ from gp,
XY from gp,
HArray1OfXY from TColgp
raises DimensionMismatch, OutOfRange
is
Create returns mutable DrawingWithRotation;
-- Specific Methods pertaining to the class
Init (me : mutable;
allViews : HArray1OfViewKindEntity;
allViewOrigins : HArray1OfXY;
allOrientationAngles : HArray1OfReal;
allAnnotations : HArray1OfIGESEntity)
raises DimensionMismatch;
---Purpose : This method is used to set the fields of the class
-- DrawingWithRotation
-- - allViews : Pointers to View entities
-- - allViewOrigins : Origin coords of transformed views
-- - allOrientationAngles : Orientation angles of transformed views
-- - allAnnotations : Pointers to Annotation entities
-- raises exception if Lengths of allViews, allViewOrigins and
-- allOrientationAngles are not same.
NbViews (me) returns Integer;
---Purpose : returns the number of view pointers in <me>
ViewItem (me; Index : Integer) returns ViewKindEntity
raises OutOfRange;
---Purpose : returns the View entity indicated by Index
-- raises an exception if Index <= 0 or Index > NbViews().
ViewOrigin (me; Index : Integer) returns Pnt2d
raises OutOfRange;
---Purpose : returns the Drawing space coordinates of the origin of the
-- Transformed view indicated by Index
-- raises an exception if Index <= 0 or Index > NbViews().
OrientationAngle (me; Index : Integer) returns Real
raises OutOfRange;
---Purpose : returns the Orientation angle for the Transformed view
-- indicated by Index
-- raises an exception if Index <= 0 or Index > NbViews().
NbAnnotations (me) returns Integer;
---Purpose : returns the number of Annotation entities in <me>
Annotation (me; Index : Integer) returns IGESEntity
raises OutOfRange;
---Purpose : returns the Annotation entity in this Drawing, indicated by Index
-- raises an exception if Index <= 0 or Index > NbAnnotations().
-- infered informations
ViewToDrawing(me; NumView : Integer; ViewCoords : XYZ)
returns XY;
-- returns the Transformation of a View from View space to Drawing
-- space.
DrawingUnit (me; value : out Real) returns Boolean;
---Purpose : Returns the Drawing Unit Value if it is specified (by a
-- specific property entity)
-- If not specified, returns False, and val as zero :
-- unit to consider is then the model unit in GlobalSection
DrawingSize (me; X,Y : out Real) returns Boolean;
---Purpose : Returns the Drawing Size if it is specified (by a
-- specific property entity)
-- If not specified, returns False, and X,Y as zero :
-- unit to consider is then the model unit in GlobalSection
fields
--
-- Class : IGESDraw_DrawingWithRotation
--
-- Purpose : Declaration of the variables specific to a
-- DrawingWithRotation Entity.
--
-- Reminder : A DrawingWithRotation Entity is defined by :
-- - Pointers to View entities
-- - Origin coordinates of transformed views
-- - Orientation angles of transformed views
-- - Pointers to Annotation entities
--
theViews : HArray1OfViewKindEntity;
theViewOrigins : HArray1OfXY;
theOrientationAngles : HArray1OfReal;
theAnnotations : HArray1OfIGESEntity;
