i made a pipe plan. i create 6 layers of the plans. i made a border so that i can plot it perfectly with the others. after that i plot save it to pdf, at first there was no problem unti i started modifing the plans then at some point i cant save some of the plans to pdf. i don't know what happen. there is no error showing and i tried to see the process log and it shows that the process has been done, but there is nothing showing in preview. even if i save it the outcome became blank.
in the plan i can't save the main, subdivision and hh plan. but i can save the line, discharge and dimension plan. they have the same property and size of border.
