The Save Selection As command saves the selected entities and all other entities on which they depend to a new project (.pw) filename. Note that
these supporting entities will be written to the new project file regardless of election, layer status, and show/hide status.
The Save Selection As command will always open a new dialogue box in which the filename and directory location can be specified.
Tip: The File, Save Selection As command allows you to save only the currently selected grid and database entities (and
their supporting entities) to a new Pointwise project file.
