Styles encapsulate and reuse sets of properties. The concept of a Name/Value match is used by Inventor to perform automated tasks. If a style in a document has a name match to a style in a library, and the values of these two styles are equal (every attribute is the same value), it is considered an exact Name/Value match.

When Inventor compares two styles of the same name, it checks all of the properties in each style to see if they are equal. For example, inside a single drawing, there can only be one dimension style named "Default (ANSI)".However, there can be a dimension style named "Default (ANSI)", and a text style name "Default (ANSI)" in the same drawing, because they are two different style types. No two styles of the same type can have the same name in the same container. Inventor uses the style name as the unique style identifier. All management interactions between documents, styles, and Style Libraries use these two mechanisms to ensure that the end object using a style has all required information. There are two general mechanisms of styles management: Style Name/Value and Substyles.
