There are two ways to do this. First go to Map Display, click on Pipelines, go to the Labels tab, and select Default Labels. These will immediately show the abbreviated company name and licence/line number on all pipelines visible on your map. If you want to label the pipeline with more information you’ll select User-Defined Labels instead. Check off the items in the Label With section that you want displayed. Close the Map Display window. In the toolbar on the left of the program go to the Objects section and select Label. In the black box that comes up you can choose your text style. To add the label click Add, click the pipeline you want to label, and then click where on the map you want the label to appear. The text will be in the same orientation as the part of the pipeline that you clicked.
