Feature Table
SIS Desktop 9.1 uses named Feature Table objects as a fast and efficient way of controlling the display, e.g. Brush, Pen, Symbol, of items.
Named Feature Table objects consist of a hierarchy of Feature Codes, each of which has styling information which graphical items with the Feature Code will use when they are drawn.
The Feature Codes hierarchy allows features of a similar type, e.g. Motorways, A-Roads, B-Roads to be grouped together for fast switching on and off.
Note: See Feature Table Properties in SIS 9.0 Programming Help for further details.
