When you merge pipe networks, no pipe network parts are moved. However, the selected parts are associated with a different pipe network name.
The Pipe Networks contextual tab is displayed in the ribbon.
The source pipe network is the pipe network that will be added to the destination pipe network.
The pipe network parts from the source pipe network are added to the destination pipe network. The source pipe network name is deleted from the Prospector tree.
Most of the part properties of the selected parts are not modified when merging pipe networks. Part properties such as the referenced surface, referenced alignment and labeling, remain unchanged when merged. The only part property that changes is the pipe network that the parts are associated with.
