Editing Hull (watercraft) (section)

==Computer-aided design==
Use of [[computer-aided design]] has superseded paper-based methods of ship design that relied on manual calculations and lines drawing. Since the early 1990s, a variety of commercial and freeware software packages specialized for naval architecture have been developed that provide 3D drafting capabilities combined with calculation modules for hydrostatics and hydrodynamics. These may be referred to as geometric modeling systems for naval architecture.<ref>{{cite web|last1=Ventura|first1=Manuel|title=Geometric Modeling of the Hull Form|url=http://www.mar.ist.utl.pt/mventura/Projecto-Navios-I/EN/SD-1.5.3-Hull%20Geometric%20Modeling.pdf|website=Centre for Marine Technology and Ocean Engineering|access-date=29 March 2018|archive-date=17 January 2024|archive-url=https://web.archive.org/web/20240117133537/http://www.mar.ist.utl.pt/mventura/Projecto-Navios-I/EN/SD-1.5.3-Hull%20Geometric%20Modeling.pdf|url-status=dead}}</ref>
