(DEFINE_) VECTOR

(DEFINE_) VECTOR

These can be edited through their own specific editing panel (see below) and using the generic Keyword Editor.

This figure shows the main menu for the editing of vector definitions.

All functions have their standard meanings as given in Standard Keyword Top Level Menu Options

CREATE Making a new vector definition

This shows the create/edit panel for vectors.

Edit DEFINE_VECTOR definition

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

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

MODIFY Modifying the attributes of an existing vector

MODIFY functions in the same way as CREATE , except that an initial definition will be present. Any modifications made to the vector definition will not be made permanent until the UPDATE_VECTOR button is pressed. At this point the local copy which has been updated is used to overwrite the version in the model.

DELETE Delete existing vector definitions

The selected vectors are deleted.

Vectors do not "own" anything, so the concept of recursive deletion does not apply, however a vector 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 vector removed.

SKETCH Sketch vector definitions

SKETCH draws the vector on top of the current graphics image.

LIST List vector summaries to screen

The selected vectors are summarised on the screen.

CHECK Check orientation vector definitions for errors

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

RENUMBER Change orientation vector labels

RENUMBER lets you change any or all vector labels within a given model using the standard renumbering panel. To change the label of an individual vector it may be simpler just to MODIFY it.
