Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.

|
---Purpose : defines IGES View Entity, Type <410> Form <0>
|
|
-- in package IGESDraw
|
|
--
|
|
-- Used to define a framework for specifying a viewing
|
|
-- orientation of an object in three dimensional model
|
|
-- space (X,Y,Z). The framework is also used to support
|
|
-- the projection of all or part of model space onto a
|
|
-- view volume.

-- Purpose : Declaration of the variables specific to a View.

|
|
-- Reminder : A View Entity is defined by :
|
|
-- - a view number for identifying the view orientation
|
|
-- - a scale factor, and
|
|
-- - a view volume to control the projection of the view into
|
|
-- a 2-D drawing space specified by a Drawing Entity.
|
|
-- The view volume is a rectangular parallelepiped with
|
|
-- limits specified by Plane Entities.
