You can use the Reset Network Labels command to reset a referenced network’s labels to match the source drawing’s labels.
Use this command when you have created a referenced pipe, and you want the labels in the referenced pipe to match the source drawing's labels, rather than the current drawing's labels.
Select a referenced pipe network part. The pipe network’s labels are deleted and replaced with labels from the source drawing. If you select parts from multiple referenced pipe networks, changes apply to all of the referenced pipe networks.
Note: After selecting this command, if there are no referenced pipe networks in the current drawing, an error message is displayed. If a source drawing is not found, an error message is displayed. If you select a part that is not from a referenced pipe network, you are prompted to select a referenced pipe network part.
