In some cases (I found that only with BIG models) when exporting Creo assembly to PVZ, it creates external structure files (separate pvs files) from top level subassemblies. I such case those branches are indicated with small blue/yellow arrows in icons of branch nodes in CreoView model tree. In CreoView UI there is a 'merge branch link' command that can be used to merge these kind of branches with main structure and get rid of the external pvs files. I have tried to find answer to two questions: 1 Why or in what case these external structure files are created? 2. is there a direct command or workaround in CreoView API to do the merge operation automaticaly without user interaction?
