Click to remove the selected used project and= keep model references across it in the model. There are two cases when you= may need to remove the used project this way.

Case #1= g>: You may need to replace a used project with the equivalent project carr= ying the same elements (but with slightly different content) and retaining = all the references.

In this case, removing the initially used project= , but keeping references creates an automated project usage that temporaril= y carries the model level references. This automated usage is invalid, sinc= e it is unconfirmed. You can confirm it by replacing the initially used project wi= th another project.

Case #2: You may need to ref= actor projects that are created with earlier MagicDraw version than 17.0.3 = and remove excessive project usages. These versions of MagicDraw have only = user-defined project usages. Because of this, a project usually had direct = user defined usages to indirectly used projects besides the indirect usages= through directly used projects. So both =E2=80=9Cproject =E2=86=92 directl= y used project =E2=86=92 indirectly used project=E2=80=9D and =E2=80=9Cproj= ect =E2=86=92 indirectly used project=E2=80=9D usage paths were present. In= this case it may be advantageous to remove the surplus usage =E2=80=9Cproj= ect =E2=86=92 indirectly used project=E2=80=9D by clicking the Remove, keep= References button.
