Polygons - Specify element symbology in the Feature Symbology panel and fill mode and color in the Polygon Symbology panel.
Points - Points can be defined as either Points (zero length lines), Cells or Text in the Feature Parameters Pane. Each point type can be further defined in the Feature Symbology, Cell Symbology or Text Symbology panels as shown:
Line symbology is defined in the Feature Symbology panel:
When imported, the features adopt the defined symbology.
