Identifier | I | The optional identifier of the representation context as used within a project. | Text |
Type | T | The description of the type of a representation context. The supported values for context type are to be specified by implementers agreements.(0=Model 1=Plan 2=NotDefined) | Integer |
Dimension | D | The integer dimension count of the coordinate space modeled in a geometric representation context. | Integer |
Precision | P | Precision | Number |
WorldCoordinateSystem | C | Establishment of the engineering coordinate system (often referred to as the world coordinate system in CAD) for all representation contexts used by the project. | Plane |
TrueNorth | N | Direction of the true north, or geographic northing direction, relative to the underlying project coordinate system. It is given by a 2 dimensional direction within the xy-plane of the project coordinate system. If not present, it defaults to 0. 1., meaning that the positive Y axis of the project coordinate system equals the geographic northing direction. | Vector |
