NAPA is the world's leading provider of tools for designing ships. This includes NAPA Steel, a software solution which is used in the early design phase for the fast and flexible creation and modification of the hull structure. However most shipyards use software from AVEVA Marine for the subsequent detailed design of the steel structures and outfit components. Although both are so-called intent-driven systems, which store almost no explicit geometry but instead record the way in which it was created and its relationships to other structural elements, the data from NAPA Steel cannot be used "as is" in AVEVA Marine. In practice, the ship designers have to reconstruct the steel structures.
