Command Options

Option	Description
Tag	Specifies the name of the attribute; this is the name by which Bricscad identifies the attribute. You can use up to 255 letters, numbers, and punctuation.
Prompt	Specifies the user prompt; this is displayed at the command prompt when the attribute is later inserted in the drawing. You can leave this field blank; Bricscad uses the tag as the prompt during attribute insertion.
Default	Specifies the default value; this is displayed in angle brackets, like <360>. As with other defaults, the user need only press Enter to accept this value. Click the Insert Field button () to assign a field value to the attribute (see the FIELD command).
Text
Text Style	Specifies the text style for the attribute text; choose from one of the styles defined in the drawing. (You can create additional text styles with the Style command.)
Justification	Specifies the justification of the attribute text, such as Center or Fit.
Height	Specifies the height of the attribute text, unless overridden by the text style. Enter a value, or click the button.
Height	Dismisses the dialog box temporarily, and then prompts you at the command prompt: Select text height - enter a value, or pick two points in the drawing.
Rotation	specifies the rotation angle of the rotation text. Enter a value, or click the button.
Rotation	Dismisses the dialog box temporarily, and then prompts you at the command prompt: Select text angle - enter an angle, or pick two points in the drawing.
Attribute Flags
Invisible	Hides the attributes; they are not displayed and not printed. (Hidden attributes can be displayed with the AttDisp command.)
Constant	Uses the default value; the user cannot change the value.
Verify	Forces the user to enter the value a second time; this helps to ensure the value is entered correctly.
Preset	Inserts attributes without prompting the user; the attributes can be changed later with the AttEdit command.
Insert Coordinates
Insert Coordinates	Dismisses the dialog box temporarily, and then prompts you at the command prompt: Select insertion point -enter coordinates, or pick a point in the drawing.
X	Specifies the x coordinate of the attribute's insertion point.
