A tag is a unique identifier for a Plant object. In a 3D model, pipe, pipe fittings, pipe supports, and equipment have a tag by default. You can add a tag to structure.
Pipe and pipe fittings have a line number tag in addition to the tag that all Plant objects can have. For more information about line numbers, see About Pipe Line Numbers.
You can add insulation to a pipe line by setting insulation properties and using a display command to control insulation visibility.
You can assign insulation to a pipe line using Data Manager, or to individual pipe components using the Properties palette.
You can display or hide insulation using the plantinsulationdisplay button on the ribbon.
