Graphic preparation rules use custom graphic rule modules to determine the display of objects passing the view style tests. Objects can be displayed as Vector Hidden Line (VHL) or resymbolized. You specify graphic modules within graphic rules as part of the view style definition. For more information, see Custom Graphic Rule Dialog Box.
Subfilters are included with some of the delivered custom graphic modules. The subfilters allow you to customize the graphic representation of objects at a granular level. You can apply a subfilter by first specifying a normal filter in the Define View Style dialog box. After specifying a filter, you use the following syntax to define a subfilter:
<Filter Name>::<Subfilter Name>
Subfilters are not compatible with all custom graphic rule modules.
