diagrams

Where can I find or how and where you can create the Default-system for diagrams.

regards

What do you mean about diagrams?
There is AVEVA Diagrams which may be used to create P&IDs.

Pipe form it asks for a primary system

If U use version 12.1.4
Open tab Admin, group Definition, button Systems. In that form systems hierarchy may be created.

You should create System Group World (SYGPWL), Each System Group world can Contain a number of System Group Area Elements (SYGPAR), Which in turn contain System elements (SYSGRP).

From Design you have to create SYGPWL.Create System Hierarchy.

mdsysf attribute is the primary system name on pipe level
