The Save Grid As command saves the grid entities, layer settings, view, grid tolerances, CAE settings, and grid-specific defaults in the current
project to a new project (.pw) file name.
Select File, Save Grid As. A file browser will appear that will allow you to choose the directory and filename in which your grid project data
should be saved.
Tip: It's not a bad idea to save your grid and database to a different
Fidelity Pointwise project file periodically to save different stages of
your grid's creation.
