CONSTRUCT COORDSYS LOCAL csyst

    

This command is used to activate a previously defined local coordinate system.

csyst = name of the local coordinate system

All point coordinates entered subsequently must be expressed in terms of the local system. Coordinates entered in this way are transformed to the global system before being stored in the database. The current coordinate system is shown by the command UTILITY TABULATE GEOMETRY STATUS.

Local coordinate systems are defined using the commands CONSTRUCT COORDSYS RECTANGUL, CONSTRUCT COORDSYS SPHERICAL, and CONSTRUCT COORDSYS CYLINDRIC. Return to the global coordinate system is achieved using the command CONSTRUCT COORDSYS GLOBAL.

Note that local systems are only used to simplify the input of geometry points and that all points will be stored in the global system. However, local systems can be shown with the command UTILITY TABULATE GEOMETRY CSYST.

Examples:

1.

CONSTRUCT COORDSYS LOCAL CS3

Activates the local coordinate system named CS3.
