Resumen
Applies symbols and Arcade expressions to layers in a map based on the symbols and rules defined in a visual specification database.
Uso
Only specification rules defined using simple SQL expressions for a single feature class and without nested joins will be converted to Arcade. If a specification rule uses complex SQL expressions or Visual Basic expressions, the rule will be skipped and a warning will be generated.
A layer in the map will only be updated if the name of the layer matches the layer name defined in one or more specification rules.
ArcMap styles containing the representations used in the visual specifications must be converted to a style file (.stylx) before running this tool. For more information, see Import a style into the project.
If the tool is run in an ArcGIS Pro project, the style should be imported into the project. If the tool is run from a project, styles associated with the project will be available. Choose a style from the Input Style File parameter or browse to an existing style file.
If a visual specification was created using multiple styles, all the symbols used in the specification should be merged to a single style before running this tool.
Regardless of the current renderer, if a layer contains specification rules, the layer renderer will be updated to use the Unique Value Renderer. Each specification rule will be added as an Arcade expression with a return code that matches the symbol name of the representation rule. Each return code will be added as a value to the unique value renderer. If the return code matches a symbol name in one of the chosen style files, the value will be displayed with that symbol; otherwise, the value will be displayed with a symbol from the default color ramp.
Unlike the ArcMap Calculate Visual Specifications tool, this tool is not intended to be used to apply symbology as each map is created. It is designed to be used as a one-time migration tool to help create map and layout templates in ArcGIS Pro.
