Hi Kevin,
I have just tested it on 2019.1 and it is working on my site.
Open data manager, switch to "Order by area", select the tagged pipe line and choose from context menu "Export to PCF". The file was created and when I have opened it with an editor, the expected content was listed here. When I use command PCF to Pipe in a new drawing, the pipe line was created correctly.
What do you see in an editor when opening the pcf-file there? When in data manager, select the node Pipe lines to see the line number as a row. Select the row of the line number and click button "Show selected item". Do you see something? Maybe your pipe line itself is "corrupt".
Best regards
Bernd
