How to Copy Symbols from one project to the other project

How to Copy Symbols from one project to the other project

Hi all
I want to use some symbols (buttons, trend, ...) of zenon Demo project in my own project but when I simply copy them from Demo project and past it in my project, it seems that it doesn't transfer its images and its preview is just some line.
Any advises about what is the standard routine for copying symbol from a project to the other project?
