Overview of Blocks In AutoCAD and AutoCAD LT, symbols are called blocks. A block is a collection of objects that are associated into a single object. Use blocks to represent objects such as a trees, fasteners, or doors. Blocks are typically defined and stored in drawings called block libraries, or symbol libraries, from which they can be inserted into other drawings. An entire drawing can also be inserted as a block. block definition for fastener block references of fastener inserted into a drawing Blocks may also include block attributes, which store data such as part numbers, dates, and performance ratings. Benefits of Blocks Using blocks makes it easier and faster to get your work done: ■ Draw efficiently by inserting, relocating, and copying blocks rather than individual objects. ■ Build a standard library of frequently used symbols, components, or standard parts. ■ Store associated data with block attributes which can be extracted to create reports. ■ Manage blocks with DesignCenter. DesignCenter provides convenient organization and access to thousands of symbols on your computer, on your local network, and on the World Wide Web. Sources of Blocks There are several sources of blocks that you can use in your drawings. ■ Your computer. Over 300 standard blocks in 15 symbol library drawings are available in the DesignCenter folder. ■ Your company network. You can also create your own blocks and block libraries, or your company may already have its own standard libraries. ■ The World Wide Web. Numerous Autodesk and commercial symbol libraries containing thousands of blocks are available. Access these using the DC Online tab in DesignCenter. NOTE Creating blocks, block attributes, or block libraries are more advanced topics and are not covered in this guide. 116 | Chapter 8 Add Symbols and Hatches
