• Page 23: Drawing Annotation

  AUTOCAD 2008 PREVIEW GUIDE Drawing Annotation Annotation is a crucial part of your design drawings and creating annotations can consume a considerable amount of your workday. Fortunately, new and improved functionality in AutoCAD 2008 enables you to annotate your drawings with greater flexibility and efficiency than ever before. Controlling Annotation Scale The frequent need for you to view the same design data at different scales can require you to produce multiple sets of annotation objects, such as text and dimensions, and multiple layers.

• Page 24
  AUTOCAD 2008 PREVIEW GUIDE Figure 32. Annotative toggles. Objects that are created using the Command Line Interface, including Text, Dimensions, Tolerance, Leaders, and Multiple Leaders, can be modified after creation to enable the Annotative property. You can use the Properties window to change the Annotative property of any existing annotative-type object. In addition to the Properties Palette, you can change the Annotative property using object-specific editors, such as the Hatch Edit dialog box, Text Formatting Toolbar, Block Attribute Manager, and Enhanced Attribute Editor.
• Page 25
  AUTOCAD 2008 PREVIEW GUIDE In addition to applying the annotative property on a per-object basis, you can create annotative styles. The Annotative option has been added to the Text Style, Dimension Style, and Multileader Style dialog boxes. If the Annotative option is enabled for a style, that style name will be preceded by an Annotative icon helping you identify which styles are annotative when viewing them in a style list.
• Page 26
  AUTOCAD 2008 PREVIEW GUIDE Figure 35. Annotative Scales. AutoCAD automatically creates a representation of the annotative object for each of the specified scales. When you select the object, you can see the multiple scale representations. If you prefer not to see all the supported scale representations when the objects is selected, you can use the SELECTIONANNODISPLAY to display only the current representation.
• Page 27
  AUTOCAD 2008 PREVIEW GUIDE Figure 37. Scale List. When you specify an Annotation Scale, the corresponding Viewport Scale is automatically applied and the annotative objects for the selected scale are displayed using their appropriate scale representations. Any annotative objects that do not contain a scale representation for the specified annotation scale are not displayed.
