Exercise 1: Create a theme for the parcels layer

A theme uses a range of colors to represent an analogous range of values. You can also use theming to show relative area, population density, water depth, or height of geographic features.

Note: This exercise uses the build_map1.dwg map you created and modified in the previous exercises.

To style the parcels layer with a theme

1. Open your finished map from the previous lesson.
   • Click OpenDrawing.
   • Locate build_map1.dwg.
   • Select it, and click Open.
2. Create a theme for the parcel layer.

   A theme is a display style. You assign styles for geospatial features by layer.

   • In Display Manager, select the Parcels layer and click Style.
     Note: If the Style Editor is docked, move your cursor over it to display it. It might be docked at the left side of the application window.
   • In the Style Editor, under Polygon Style For 0 - Infinity Scale Range, click New Theme.
     

     Click New Theme to define a theme for the Parcels layer.

To continue this tutorial, go to Exercise 2: Define the theme.
