Display : Adding Elements to the Display : Defining Colours

COLOUR ACTIVE CE VISIBLE CLASH OBST AIDS

These commands allow colours to be defined so that different types of item in the display may be distinguished by means of colour. Certain items such as current element and active element colours have default settings, but these may also be redefined.

The colours may be assigned by using the COLOUR command to define the Red-Green-Blue mix for a colour number or to assign a predefined colour mix by name. MODEL allows the use of 115 user-definable colours, plus some specific ones which are assigned to items which need to be readily distinguishable in the display.

Definitions:

•

The Active element is the significant element (and its components) being worked on.

•

The Current Element (CE) is the actual element currently being accessed.

•

The Visible design consists of the design elements which is required to be displayed (but which the user is not currently working on).

•

A Clashing element is an element whose current position and geometry are being tested for interferences against other elements in the design and which has been found to clash (refer to Clash Detection for further information).

•

An Obstructing element is any of the elements in the design against which a clashing element is being tested for interferences and which has been found to clash.

•

An Aid includes tags (markers), axes and other graphical annotations.

The predefined colour mixes which are specified by name are as follows:

Note:

When colours are mixed in their Red, Green and Blue constituents, the command line must contain values for all three constituents in the correct order. The numbers entered for the relative proportions of the basic colours must each be in the range 0-100, but they are not percentages of the overall colour and so do not need to add up to 100.
