An attribute is informational text associated with a block. An attribute definition is a template for creating an attribute. Use ATTDEF to work on the command line and DDATTDEF to work in the Attribute Definition dialog box.

Attribute Mode

Sets four optional modes. Entering i, c, v, or p toggles among the modes. The AFLAGS system variable stores the current mode settings and can be used to set the default modes.

• Invisible. Specifies that attribute values will not appear when you insert the block. The ATTDISP command overrides Invisible mode.
• Constant. Gives attributes a fixed value for block insertions.
• Verify. Prompts for verification that the attribute value is correct when you insert the block.
• Preset. Sets the attribute to its default value when you insert the block.

Attribute Tag

Enter a name for the attribute. The attribute tag identifies each occurrence of an attribute in the drawing. The tag can contain any characters except spaces or exclamation marks. AutoCAD LT changes lowercase letters to uppercase.

Attribute Prompt

Enter a prompt. The prompt you enter is displayed when you insert a block that contains an attribute definition into your drawing. If you press ENTER, AutoCAD LT uses the attribute tag as the prompt. If you turn on Constant mode, this prompt is not displayed.

Default Attribute Value

Enter the default attribute value. The default attribute value appears when a block is inserted into your drawing. A default value is not required. If Constant mode is turned on, AutoCAD LT skips this prompt and displays the Attribute Value prompt instead.

DDATTE and ATTEDIT edit attributes independently of the block definition with which they're associated. DDATTEXT and ATTEXT extract attribute data.
System Variables: ATTDIA causes the INSERT command to use dialog boxes for entry of attribute values. ATTMODE controls the attribute display mode. ATTREQ determines whether the INSERT command uses default attribute settings during insertion of blocks.
