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) |
44 | |
45 | Coord (me) returns Pnt; |
46 | ---Purpose : returns the nodal coordinates |
47 | |
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 |
52 | |
53 | SystemType (me) returns Integer; |
54 | ---Purpose : Computes & returns the Type of Coordinate System : |
55 | -- 0 GlobalCartesian, 1 Cartesian, 2 Cylindrical, 3 Spherical |
56 | |
57 | TransformedNodalCoord (me) returns Pnt; |
58 | ---Purpose : returns the Nodal coordinates after transformation |
