I’d like to refer to libraries. I used to create references in EclipseIDE and i am unsure how to do this in SysIDE.

If those libraries are textual files, you should just be able to drop them into the same workspace and do

```auto
private/public import <library name>

```

like with any other SysML v2 package

Just a bit of clarification:

Say you have a package in `mylib.sysml`

```auto
package MyLib {
    part p;
}

```

Then as soon as you put `mylib.sysml` in your workspace, the name `MyLib` becomes available anywhere. That is to say, whenever you type `MyLib` it will refer to the package element specified in `mylib.sysml`. In particular, `MyLib::p` refers to the part usage you put in your package.

A `private/public import` statement is only necessary if you want to re-export the names from `MyLib` elsewhere. For example

```auto
package OtherPackage {
    import MyLib::p;
    
    // use p
}

```

makes `p` available (also!) as just `p` inside `OtherPackage`, but you could just as well have used `MyLib::p` directly, without an import.

Thank you @TiloWiklund and sorry for my unclear question. I was exactly looking for what @Arnas responded.
