17 class Node from IGESAppli inherits IGESEntity
19 ---Purpose: defines Node, Type <134> Form <0>
20 -- in package IGESAppli
21 -- Geometric point used in the definition of a finite element.
27 TransfEntity from IGESData,
28 TransformationMatrix from IGESGeom
34 -- Specific Methods pertaining to the class
38 aCoordSystem : TransformationMatrix);
39 ---Purpose : This method is used to set the fields of the class Node
40 -- - aCoord : Nodal Coordinates
41 -- - aCoordSystem : the Nodal Displacement Coordinate
42 -- System Entity (default 0 is Global
43 -- Cartesian Coordinate system)
45 Coord (me) returns Pnt;
46 ---Purpose : returns the nodal coordinates
48 System (me) returns TransfEntity;
49 ---Purpose : returns TransfEntity if a Nodal Displacement Coordinate
50 -- System Entity is defined
51 -- else (for Global Cartesien) returns Null Handle
53 SystemType (me) returns Integer;
54 ---Purpose : Computes & returns the Type of Coordinate System :
55 -- 0 GlobalCartesian, 1 Cartesian, 2 Cylindrical, 3 Spherical
57 TransformedNodalCoord (me) returns Pnt;
58 ---Purpose : returns the Nodal coordinates after transformation
63 -- Class : IGESAppli_Node
65 -- Purpose : Declaration of variables specific to the definition
68 -- Reminder : A Node instance is defined by :
69 -- - Nodal Coordinates
70 -- - the Nodal Displacement Coordinate System Entity
73 theSystem : TransformationMatrix;
