I have a problem with my palette. it shows only some of the available symbols e.g. in the standard UML section of the palette, there are no symbols for classes. BUT: When I open the example graphs, there is such a class diagram, having also class specific symbols. The same is for ERM diagrams in the examples.
And I simply don't know where to find and how to add all those symbols. Where can I find those extansions?
Thank you very much!
