A style library contains the definition of individual style types. When you apply a style to an object in a document, the attributes of the style are retrieved from the style library.
By default, all styles in the style library associated with the active drafting standard are available for formatting objects in documents. Usually the style library is managed by the CAD administrator, so that the integrity of the library is maintained across design files.
You can use a single global library so that all designers use the same styles, or you can specify a library for a specific set of design files.
Autodesk Inventor LT provides a style library that contains a set of common materials, colors, and lighting for parts, as well as common drafting standards such as ANSI, ISO, and DIN for drawings. Style libraries are a common source of styles for all documents. Each style library is a collection of .xml files, one for each style type. For example, there is a file for dimensions, layers, and all other style types.
You can see a list of the style types in the browser of the Style and Standard Editor. Click 
.
A style library is a good way to manage styles so that they can be shared across documents. For example, material styles can be made available so that all parts have access to the same definitions. In drawings, using styles assures uniform annotations, including such details as arrowheads, dimensions, leaders, center marks, and so on.
A good time to start using style libraries is when you start a new design project, are new to Autodesk Inventor LT, or are an individual designer or work in a small group. You can use the default style library associated with the drafting standard.
To get started, you can use the default styles that are associated with each drafting standard. That is, ANSI comes with its own set of styles, as does DIN, JIS and other international standards. As your company standardizes on how to format objects, styles can be added or edited, and the changed styles saved to the style library. New documents will automatically have the styles available for formatting.
You might want to transition to using a style library later if you have active legacy files, you work in a large workgroup, and have need for one or more custom style libraries.
Use a style library when:
Consider using a Style Library out of the box if you:
Working without a style library
The Application Options dialog box includes a setting that turns off a style library. When you turn a style library off, styles are only available in a document template. Use the document template for access to styles. If you change styles in the templates, all future documents will access the changes, but previously created documents will not.
If you later decide to work with the style library on, update the styles for previously created documents.
To transfer styles from one document to another, import or export styles.
To specify the style library to use, turn on the style library and then specify the default style library on the File tab of the Application Options dialog box.
Use a style library when:
Save styles to a style library
You can create or edit a style, and then save the changed version to the style library. If the style has the same name as a style that exists in the style library, it replaces the library version.
Access to a style library may be controlled by the CAD administrator. It is usually a good practice for the CAD administrator to maintain a master copy of a style library and copy it if modifications are needed. Using this practice, you can always retrieve the default styles from the master library.

Style Library Manager is a stand-alone tool used for the administration of style libraries. This tool works directly with the style library XML files on disk, and is not used in the management of styles inside Autodesk Inventor LT documents. It is accessed from the Microsoft® Windows® Start menu, and is found in the Tools submenu for Autodesk Inventor LT.
Use Style Library Manager to:
Autodesk Inventor LT installs with a default style library designed to leverage of all new capabilities of styles.
You can create your own style libraries in two different ways: Copy an existing style library or create an empty style library. The target directory for the new library cannot include other style library.
After you create a style library, use Style Library Manager or Style and Standard Editor to add or remove particular styles.
Rename and delete styles inside of a library
Use Style Library Manager to rename styles inside of a library. Renaming a style in the library does not rename the same style in any other library or document. Once a style is renamed, all document copies of the style loose their name match and are considered locally cached style.
The only way to delete a style from a library is through the Style Library Manager.
Styles are copied between libraries using the Style Library Manager. To copy a style from one library to another, load the source library into Style Library Manager and click the Copy Selected Styles command between the Style Library 1 and Style Library 2 panes. See the Style Library Manager Help for more details.
A style library is a group of named XML files in a directory. There is one XML file per style type (for example: color.xml, text.xml). Since the names of the XML files must be the same for each style library, only one library can exist in a directory.
To be considered a valid style library, all predefined XML files must be present in the directory.
The best way to share a subset of styles from a library (for example, a single standard or all materials form a specific library) is to use the Import/Export styles function in the Style and Standard Editor, or create an empty style library and copy the desired styles using the Style Library Manager.
Incomplete Style Libraries
Though a style library is made up of several separate XML files, Autodesk Inventor LT and the Style Library Manager treat the library as a single entity. If some of the predefined XML files required for a style library are missing from a directory, Autodesk Inventor LT displays an error message indicating files are missing and cannot be loaded.
Restoring the Autodesk Inventor LT Default Style Library
A utility for restoring the default Design Data directory files is located on the Autodesk Inventor LT Install CD in the Support directory. This utility replaces the original default style library that ships with Autodesk Inventor LT, as well as the Thread.xls and Clearance.xls spreadsheets.
In a multi-user environment, CAD administrators may want to prevent users from changing a style library.
If a single XML file is read-only, the entire library is treated as read-only.
The Autodesk Inventor LT Pack and Go utility optionally includes a style library. It is included in the Design Data subdirectory.
You can create a style library using one of several methods. In general, new style libraries are created by CAD administrators so that uniform styles are assured throughout all design documents.

Copy, rename, or delete library styles
The Style Library Manager is primarily used by CAD administrators to copy, rename, and delete library styles. The CAD administrator controls the style library contents and assures that designers using styles have the same style definitions, assuring uniform document formatting.
The Style Library Manager uses the Create New Style Library command to create new style libraries.
In general, style libraries are read-only, except to make necessary changes. The Styles Library Manager uses the read-only file property, and disregards the library status specified by the Use Style Library=Read Only option in Application Options.
Any changes made to a style library are not available in other documents until the current Autodesk Inventor LT session closes and a new session is opened.
You can create new styles or rename styles in a document, but they affect only that document. Take a separate step to save a new or changed style to a style library to replace the library version. Access to the style library may be controlled by the CAD administrator.

Comparing Styles Between Definitions
If a style exists in both Style Libraries and is an exact name value match (that is, Equal), then the text in the style lists has a normal font display.
If a style exists in both Style Libraries, is an exact name match, and is not a value match (that is, Not Equal), then the text for this style name displays as bold, underlined, and red.
If a style only exists in one Style Library (that is, is Unique), then the text for this style name displays as bold, underline, and blue.

Substyles are only copied from one style library to another if they do not exist in the target library. To avoid replacing an existing style accidentally, you are prompted to replace the target style with the source style. It occurs if a substyle exists in the target style library, and it is different from the substyle in the source library.
When copying a style library, if a source style and one or more of its substyles differ from the destination library, you are asked to select which substyles to copy to the destination library.
For example, a dimension style uses the text style as a substyle. If the text substyle referenced by the dimension style is different from the text style in the destination style library, confirm to replace the destination text style with the text substyle from the source style library.
If you choose to use a combination of Yes and No in the Overwrite column, the style in the destination style library is not identical characteristics compared to the source.
Access: | In the Style Library Manager dialog box, click the Show Unique Styles command or Show Mismatched Styles command to list styles in red text. Listed styles do not match in the source and destination style libraries. Right-click a red style name and then click the arrow button to copy it. The Manage Styles dialog box opens. |
Style Name | Lists the destination style name and its standard. |
Path | Shows the path of the destination style. |
Type | Lists the style type. |
