I always import my plant symbols from one design into another design, but all of a sudden it doesn't seem to work....
As soon as I want to copy a plant symbol which I created previously into my current drawing I can’t select it and it doesn’t display any graphics only an outline.
When I double click on it to enter the 2D Graphics, it is empty and then the image also disappears from my resource browser. The definition is still present.
What am I doping wrong.
