This figure shows the main menu for the editing of co-ordinate systems. All functions have their standard meanings as given in Standard Keyword Top Level Menu Options

CREATE Making a transformation definition

See Edit of Define Transform. for more details about the Create / Modify panel for Transformations.

COPY Copy existing transformation(s) to make a new transformation

The selected coordinates are copied. (Transformations do not "own" anything, so the concept of recursive copying does not apply.)

MODIFY Modifying the attributes of an existing transformation

MODIFY functions in the same way as CREATE , except that an initial definition will be present.

Any modifications made to the section definition will not be made permanent until the UPDATE_TRANSFORMATION button is pressed. At this point a the local copy which has been updated is used to overwrite the version in the model.

DELETE Delete existing transformation definitions

The selected transformations are deleted.

Transformation definitions do not "own" anything, so the concept of recursive deletion does not apply, however a transformation that is referred to (ie "owned") by some higher order item will not be deletable unless that item is deleted too, or its reference to the transformation removed.

SKETCH Sketch transformation summaries

The selected transformation definitions are sketched on the screen.

LIST List transformation summaries to screen

The selected transformation definitions are summarised on the screen.

CHECK Check definitions for errors

The selected transformation definitions are run through the standard checking routines.

RENUMBER Change transformation labels

Lets you change any or all transformation labels within a given model using the standard renumbering panel.

To change the label of an individual transformation may be simpler just to MODIFY it.
