In AutoCAD, an attribute is data that is associated with a block. You assign attributes to provide additional information about an object. You can access and view pipeline and component attribute values using the Edit Attribute command.
Query pipeline attributes
You can query pipeline attributes only if a pipeline placeholder exists. The creation of pipeline placeholders is controlled by the Use pipeline placeholders setting on the Attributes tab. You must select this setting prior to model generation.
Open a generated model in AutoCAD. For more information, see Open and view a model in AutoCAD.
Right-click a pipeline placeholder, and then select Edit Attribute.
The software opens the Enhanced Attribute Editor dialog box and displays the pipeline tags.
Query component attributes
Open a generated model in AutoCAD.
Right-click a component in the model, and then select Edit Attribute.
The software opens the Enhanced Attribute Editor dialog box and displays the component tags.
The options that you select in the Attribute Creation and External Data sections on the Attributes tab prior to model generation determine the identity and the quantity of the attributes that the software displays.
The format of the attribute display depends on the version of AutoCAD you are using.
For more information about querying tags, refer to the Help documentation delivered with AutoCAD.
