Hello Changsong Ling, First - What version of OpenPlant PID are you running? Go to Help About and look for the build number. As an example 08.11.11.43 The seed file should have no bearing on the line jumper settings. This is controlled by the schemas and is on the PIPING_NETWORK_SEGMENT class. There should be a Custom Attribute. The custom attribute is Jumper Mapping . This is by default inherited from the PID schema. You need to verify that this is there. In the PID.cfg file, there is also a setting there for Jumper setting when intersecting lines have the same class - IE MAJOR_PIPELINE. # Run breaking heirarchy, when intersecting runs have same class # 1 means horizontal segment will not break # 0 means vertical segment will not break SCHEMATICS_JUMPER_SAME_CLASS_HORIZONTAL_PRIORITY = 1 Tony DeRosa Bentley Plant
