LT users have had to do without the Express Tools because LT doesn’t support the language they’re programmed in. However, now that these layer tools are part of the core program, LT users at last have access to the most useful of the former Express Tools.
Using AutoCAD DesignCenter
DesignCenter is a dumb name for a useful, if somewhat busy, palette. (Chapter 2 describes how to turn on and work with palettes.) The DesignCenter palette is handy for borrowing data from all kinds of drawings. Whereas the Properties palette, described earlier in this chapter, is concerned with object properties, the DesignCenter palette deals primarily with named objects: layers, linetypes, block (that is, symbol) definitions, text styles, and other organizational objects in your drawings.
Named objects
Every drawing includes a set of symbol tables, which contain named objects. For example, the layer table contains a list of the layers in the current drawing, along with the settings for each layer (color, linetype, on/off setting, and so on). Each of these table objects, be it a layer or some other type, has a name, so Autodesk decided to call them named objects (duh!).
Neither the symbol tables nor the named objects appear as graphical objects in your drawing. They’re like hardworking stagehands who keep the show running smoothly behind the scenes. The named objects include

Layers (this chapter)
Linetypes (this chapter)
Text styles (Chapter 10)
Dimension styles (Chapter 11)
Block definitions and xrefs (Chapter 14)
Layouts (Chapter 4)
When you use commands such as LAYER, LINETYPE (LT), and DIMSTYLE (D), you are creating and editing named objects. After you’ve created named objects in a drawing, DesignCenter gives you the tools to copy them to other drawings.
Getting (Design)Centered
The DesignCenter palette (shown in Figure 5-10) consists of a toolbar at the top, a set of tabs below that, a navigation pane on the left, and a content pane on the right. The navigation pane displays a tree view with drawing files and the symbol tables contained in each drawing. The content pane usually displays the contents of the drawing or symbol table.

The four tabs just below the DesignCenter toolbar control what you see in the navigation and content panes:
Folders: This tab shows the folders on your local and network drives, just like the Windows Explorer Folders pane does. Use this tab if the drawing you want to copy from isn’t currently open in AutoCAD.
Open Drawings: This tab shows the drawings that are currently open in AutoCAD. Use this tab to copy named objects between open drawings.
History: This tab shows drawings that you’ve recently browsed in DesignCenter. Use this tab to jump quickly to drawings that you’ve used recently on the Folders tab.
DC Online: This tab shows parts libraries that are available on Autodesk’s and other companies’ Web sites. This tab is essentially an advertising vehicle for software companies offering to sell you symbol libraries and manufacturers encouraging you to specify their products. Browse the offerings on this tab to see whether any of the online libraries can be useful in your work.
The toolbar buttons further refine what you see in the navigation and content panes. A few of these buttons toggle off and on different parts of the panes.
Follow these steps to use DesignCenter:
1. If it isn’t already, open DesignCenter by choosing ToolsODesignCenter.
You can also click DesignCenter on the Standard toolbar or press Ctrl+2.
2. Load the drawing(s) whose content you want to view or use into the navigation pane on the left.
If a drawing doesn’t appear on the Open Drawings tab, click the Load button — the first one on the DesignCenter toolbar — to load it into the navigation pane.
3. Navigate the symbol tables (such as blocks and layers), viewing their individual named objects in the content pane on the right.
4. If you need them, drag or copy and paste individual named objects from the content pane into other open AutoCAD drawings.
Copying layers between drawings
The following steps copy layers from one drawing to another using DesignCenter. You can use the same technique to copy dimension styles, layouts, linetypes, and text styles.
