WARNING

The ARD language is defined in a serial fashion and it is very possible for entries early in the file to be modified by later entries, if they contain EXCLUDE regions. e.g. a file containing a definition of an annulus followed by a circle will behave as you would expect, however, if the annulus and circle are the other way round the circle definition will probably be completely superceeded by the annulus. At present this effect is limited to ANNULI, beware that the XSPOKES language definition contains an annulus. When producing a file containing the ribs definition, the ribs should be selected first.
