The easiest way to apply symbols to features and graphics is to choose from those stored in the system styles provided with ArcGIS Pro. You can search for appropriate symbols by name or a keyword, or browse through a visual palette to find what you need. You can apply symbols directly as they are or modify them first. You can achieve a wide variety of appearances by adjusting symbol properties. Optionally, you can save symbols—modified or not—in a style for later reuse.
Find symbols in the symbol gallery
You use the Format Symbol mode of the Symbology pane to change symbols as they are applied to features. This mode of the pane has two tabs: Gallery and Properties. You find and apply ready-made symbols from the Gallery tab; you use the Properties tab to make adjustments to the current symbol.
You can browse the symbol gallery to find a suitable symbol, or you can search for one by typing a search term. The gallery shows symbols of the current type (point, line, polygon, or text) that are contained within the project styles, or it will show the results of your search. You can extend your search to all system styles (those installed with ArcGIS Pro). Choose either Project styles or All styles to control which styles are searched.
Change the gallery view
Hover over a symbol in the gallery to see the symbol name, the style in which it is stored, its category, and its tags. In the Options list, use Icon view to see a lot of symbols at once; use List view when symbol names are lengthy. Group symbols either by the style they are in or by the category assigned to them. Sort the symbols alphabetically or by their native order.
Search for symbols
Each symbol stored in a style contains searchable tags that describe its characteristics. Symbols in styles also have a category. A category is just like a tag but is used in some parts of the application to control which core symbols are shown in certain galleries. In your own styles, you can use the category as a main organizational tag. Search results consist of symbols where the search term matches either the symbol name, the symbol category, or symbol tags.
Search results match the beginning of the search term. For example, searching for tar will find symbols with the word target in their name or tags, but not symbols with the word star. If necessary, use the * character as a wildcard to represent any number of characters. For example, searching for *tar will find symbols with both target and star. Previous searches can be accessed by clicking the small down arrow icon on the right end of the Search box.
Work with symbol tags
To return useful search results, each symbol contains descriptive tags. Tags are strings that identify key information about each symbol. They can include references to the appearance of a symbol, its origin, its usage, or any combination of those. Tags can be up to 255 characters long, including spaces. The core styles that are installed with ArcGIS Pro are read-only; they cannot be modified. The tags on the symbols in these styles are prepopulated to reflect the graphic properties of the symbols, such as the primary color and the symbol type, as well as other pertinent information. Tags in editable styles can be used to describe any relevant aspect of the symbol, such as a related project, map, layer, scale, or specification.
