To Create and Attach an Attribute Definition

Creates an attribute definition for storing data in a block.

1. Click Drafting tab > Block panel > Define Attribute.
2. In the Attribute Definition dialog box, set the attribute modes and enter tag information, location, and text options.
   • Attribute tag name. This tag can contain any characters except spaces or exclamation marks (!). Lowercase letters are automatically changed to uppercase.
   • Attribute Prompt. This specifies the prompt that is displayed when you insert a block containing this attribute definition. If you press Enter, the attribute tag is used as the prompt.
     Note: If you do not enter a prompt, the attribute tag is used as a prompt. If you select Constant in the Attribute Options area under Advanced Options, the Prompt option is not available.
   • Default Attribute Value. This specifies the default attribute value. The default attribute value appears when a block is inserted into your drawing.
3. Click Save
4. Create or redefine a block (BLOCK). When you are prompted to select objects for the block, include the attribute in the selection set.

   To use several attributes together, define them and then include them in the same block.
