Creating a new specification

You have to set the following to create specifications:

• Table location—Where the information related to specifications is stored. The table can be stored in a geodatabase you specify.

  The product library geodatabase is recommended if one is being set up and used in other workflows. The information in the specifications table is used to associate your rules, stored in the rules table, with the appropriate specification.

• Name—The name you have defined for the specification. This can correspond with a product specification or a different grouping you would like to use for the rules you are going to define.
• Description—A brief description of the specification you are creating. If you have used an acronym as the specification name, the description can be the definition of the acronym.
• Calculation method—Determines when and how the visual specifications values are calculated and updated when geodatabases have edits applied.

  The Calculate Specifications parameter is unique to each user login and is persisted across map document sessions. The parameter setting can be changed at any point and, once it is changed, affects the workflows of subsequent map documents that use that set of visual specifications.

  Extra columns are added to feature classes that use visual specifications that hold the representation rule, representation overrides, and fields information.

步骤:

1. Click the Visual Specifications button on the Production Symbology toolbar.
