The Vector Display Folder controls options for the display of vector data (areas, lines, and points).
The Render section contains the settings for which types of vector features (areas, lines, or points) are to be displayed when loaded. You can use these settings to turn off an entire class of features all at once. For a finer degree of control, see the Filter section described below.
The Select From section contains the settings which determine which vector object types (i.e. areas, lines, points) the Digitizer or Feature Info Tool will consider when selecting objects.
The Filter section allows you to select which specific area, line, and point feature types you wish to display. By default, all feature types are displayed.
The Vector Map Detail setting controls the simplification of displayed vector data. This is useful when working with a large of amount of vector data loaded into one project. For example: If you had all of the roads for an entire state loaded at once, you could slide the detail slider to the left to make minor roads been hidden until you zoomed in sufficiently far on the data. The right most (default) setting causes all vector data to be displayed regardless of zoom scale. This setting does not affect the display of raster or elevation data sets.
The Vector Layer Ordering During Draw settings control the order in which data from vector layers is displayed. The default setting (order by type before layer order) is that all vector data is drawn after any other loaded raster or elevation data, regardless of how the vector layers are ordered in the Overlay Control Center. All area features from all layers will be drawn first, followed by all line features from all layers, and finally all point features from all layers. Within each grouping (e.g. areas, lines, or points), the drawing order will be determined first by type, and then by layer ordering.
The second draw order option (order first by layer, then by type within a layer) specifies that the order of the vector layers in the Overlay Control Center should take precedence over all else when drawing. This means that if a vector layer is before a raster layer in the Overlay Control Center's draw order, that vector layer will draw underneath that raster layer if they overlap.
