Changes are only available in 21.1 and will be made available in 2019 and 2020 in a later version. 

Select Pipes from Spanning Labels

Several Naviate commands have been supplemented with support for Spanning Labels. Instead of selecting start and end pipe, you can select a spanning label instead. There is also a Select objects from Spanning label to select the included pipes.

 

Pipe Subassembly

The Naviate Pipe subassemblies can be used for Pressure Pipe networks as well, and this has been updated to include fittings and appurtenances as well.
