When I save a diagram,in option save file dun appear *.vpd let I save file .vpd,just appear SDE_diagram, I put name for file.vpd already,but I dun find those file *.vpd in project *.vpp.

Dear Dieu,

You are not require to save the diagrams individually. The diagram information are already inside the project file. If you want to export your diagram(s) as a standalone project. You can make use of the project export function.
