Copying specification rules for calculated fields

If you added and renamed specifications, specification rules need to be added to them. This process may include copying and pasting calculated representation or field rules from existing specifications into the new or updated one.

Specification rules can be copied within a specification or to a different specification. When specification rules are copied, you can edit the rule's Structured Query Language (SQL) statement or Visual Basic Script Edition (VBScript) expression as well as the representation rule being used. For example, if you want to change the script and associate a different symbol with a similar rule, you could modify the script and change the representation rule symbol.

步骤:

1. Choose the layer that contains the text strings you want to copy.
2. Right-click the layer and click Properties.
