Phpstorm, create a custom UML diagram

Question

PhpStorm has a function to create UML diagrams based on existing classes.

But I need to create and save my own diagrams, which will have objects for non-existing classes. For example, I need to create a database diagram and a UML diagram for some classes of a new function.

Can I do this via phpstorm?

Answer 1

No, go to the documentation Merging Jetbrains on UML diagrams in Phpstorm and this phpstorm post allows you to create different types of UML diagrams of your code base, the only model is the code base itself. Thus, you cannot have classes only in the diagram.
