Feature Class

Describes a discrete entity within a batched RenderGraphic that can be grouped with other such entities in a FeatureTable. Features roughly correlate to elements: a Tile's graphics combines geometry from every GeometricElement that intersects the tile's volume, so each element produces at least one feature. However, an element's geometry stream can contain geometry belonging to multiple different combinations of SubCategory and GeometryClass, so an individual element may produce more than one feature.

see FeatureOverrides for customizing the appearance of individual features.
