AttDef – BricsCAD Centro Assistenza

Defines how a block's attributes will be created through a dialog box.

Accessing the Command

: attdef

Displays a dialog box:

Enter options, and then click OK. To create and use attributes, follow these steps:

Use this command to define attributes.
Use the Block command to combine attributes and symbols into a block.
Use the Insert command to insert the blocks, answering the prompts with data with attributes.
When it is necessary to edit the values of the attributes, use the AttEdit command.
To extract attribute values to external data files, use the AttExt or DataExtraction commands.

You can use the AttDisp command to toggle the display of attributes in drawings on and off.

Attribute Options	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 Options	Description
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 to pick two points in the drawing: Dismisses the dialog box temporarily. 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 to pick two points in the drawing: Dismisses the dialog box temporarily. Prompts you at the command prompt Select text angle - enter an angle, or pick two points in the drawing.
Annotative	Sets the Annotative property of the attribute text.

Attribute Flags Options	Description
Invisible	Hides the attributes from view; they are not displayed and not printed. Hidden attributes can, however, be displayed with the AttDisp command.
Constant	Specifies a default value that the user cannot change.
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.
Lock Position	On - locks the position of the attribute within the block reference. Off - unlocked attributes can be moved relative to the rest of the block using grip editing.
Multiple lines	On - allows the use of multiline text Off - limits text to a single line When the Multiple lines flag is checked, the button () displays next to the dimmed Default text field. When you click the button, the Define Attribute dialog box temporarily closes to let you define a multiline text entity. Prompts you: Specify location of multiline attribute - specify a point, and then the MTEXT command launches. Type the text for the attribute, then click the OK button on the Text Formatting toolbar to return to the Attribute Definition dialog box.

Insert Coordinates Options	Description
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.
Y	Specifies the y coordinate.
Z	Specifies the z coordinate.
