748 AutoCAD and Its Applications—Basics Copyright Goodheart-Willcox Co., Inc. • Keep backup copies of all fi les in a secure location. • When you revise symbols, update all fi les containing the edited symbols as appropriate. • Inform all users of any changes to saved symbols. Storing Symbol Libraries Store symbol libraries on the local or network hard drive. This location is easy to access, quick, and more convenient to use than portable media. Removable media, such as a removable hard drive, USB fl ash drive, or CD, are appropriate for backup purposes if a network drive with an automatic backup function is not available. In the absence of a network, use removable media to transport fi les from one workstation to another. Use a system of folders and fi les to store and organize symbol libraries. Store content outside of the AutoCAD system folders to keep the system folders uncluttered, and to differentiate your folders and fi les from AutoCAD system folders and fi les. A good method is to create a separate folder with a name such as \Blocks to store all blocks. Then use folders with names such as \Architectural, \Electrical, \Plumbing, and \Structural to group blocks associated with specifi c disciplines or applications. If you save multiple symbols within a single drawing, use the Other Drawing tab of the Blocks palette, DesignCenter, or the Tool Palettes palette to insert the symbols as needed. This system often works best when you use several drawing fi les to group similar or discipline-specifi c symbols. For example, create different symbol library drawing fi les with names such as Electronics, Fasteners, Piping, and Structural Shapes. Limit the symbols in a drawing to a reasonable number so you can easily fi nd and load the symbols. Arrange drawing fi les saved on the hard drive in a logical manner. All worksta- tions in a non-networked classroom or offi ce should have folders with the same names. Figure 24-16. An example of an architectural symbol library created by saving multiple blocks in a single drawing. The “X” symbols indicate insertion points and are not part of the blocks.
