class SolidAssembly from IGESSolid inherits IGESEntity
---Purpose: defines SolidAssembly, Type <184> Form <0>
-- in package IGESSolid
-- Solid assembly is a collection of items which possess a
-- shared fixed geometric relationship.
--
-- From IGES-5.3, From 1 says that at least one item is a Brep
-- else all are Primitives, Boolean Trees, Solid Instances or
-- other Assemblies
uses
HArray1OfIGESEntity from IGESData,
TransformationMatrix from IGESGeom,
HArray1OfTransformationMatrix from IGESGeom
raises DimensionMismatch, OutOfRange
is
Create returns mutable SolidAssembly;
-- Specific Methods pertaining to the class
Init (me : mutable;
allItems : HArray1OfIGESEntity;
allMatrices : HArray1OfTransformationMatrix)
raises DimensionMismatch;
---Purpose : This method is used to set the fields of the class
-- SolidAssembly
-- - allItems : the collection of items
-- - allMatrices : transformation matrices corresponding to each
-- item
-- raises exception if the length of allItems & allMatrices
-- do not match
HasBrep (me) returns Boolean;
---Purpose : Tells if at least one item is a Brep, from FormNumber
SetBrep (me : mutable; hasbrep : Boolean);
---Purpose : Sets or Unsets the status "HasBrep" from FormNumber
-- Default is False
NbItems (me) returns Integer;
---Purpose : returns the number of items in the collection
Item (me; Index : Integer) returns IGESEntity
raises OutOfRange;
---Purpose : returns the Index'th item
-- raises exception if Index <= 0 or Index > NbItems()
TransfMatrix (me; Index : Integer) returns TransformationMatrix
raises OutOfRange;
---Purpose : returns the transformation matrix of the Index'th item
-- raises exception if Index <= 0 or Index > NbItems()
fields
--
-- Class : IGESSolid_SolidAssembly
--
-- Purpose : Declaration of variables specific to the definition
-- of the Class SolidAssembly.
--
-- Reminder : A SolidAssembly instance is defined by :
-- a collection of items (Items) and transformation matrix
-- entities (Matrices)
theItems : HArray1OfIGESEntity;
-- the collection of items
theMatrices : HArray1OfTransformationMatrix from IGESGeom;
-- the transformation matrices
end SolidAssembly;
