Sea attached a sample.
My P3dLineGroup.tag is 80 P 80032 A2.
When i generate isometric and PCF file, the name of PCF file is correct, but inside PCF file the PIPELINE-REFERENCE take the value "80 P 80032 A2-2". From where P3D add the "-2" ??
The consequences are that on iso line tags this "-2" appear too ! (because isoconfig.xml use the PIPELINE-REFERENCE field)
How the PIPELINE-REFERENCE field is generate from model to PCF file ? (I did found that in isoconfig.xml)
Where does the index "-2" at the end of the number ?
The 2 after your user-defined tag is a reference numbe to the splittet isometric drawing. See attached picture. If your isometric will be splittet in two drawings 80 P 80032 A2-1 and 80 P 80032 A2-2.
True the iso spleeted have an indice added in dwg name and file name. I get it.
But there is only one PCF file and only one PIPELINE-REFERENCE per line (even if it's iso is spleeted)
So sorry but it is not normal to have this indice in PIPELINE-REFERENCE of PCF file
This is strange. I can not recreate it here. I tried also to migrate a 2012 project to a 2013 project. But get no added number at the end of the tag as you get when isometrics are not splitted. I will send you via email a ftp-link there you can upload your project.
