Select Part Configuration in the Feature Tree
The existing geometry of a part forms its default configuration.
In addition to this, a part may have configurations in which one or more features of the part have been hidden, or more have been modeled, making the visible geometry of the part different from the default configuration.
You can create, activate and delete configurations using the functions in the feature tree of the part.
Correspondingly, you can select the assembly configuration in the assembly tree.
