Erasing a wire number deletes the main wire number of a network, or a wire number copy. Select a wire number copy precisely to erase just that copy, leaving the main wire number of the network and any other copies in place. Select the main wire number to delete it and all wire number copies.
AutoCAD Electrical automatically hides wire numbers when the wire number is on the same network as a terminal symbol that carries a copy of the wire number (WIRENO attribute). You can hide or show wire numbers manually.
