2D IN A 3D WORLD: CLASSIFICATION DRAWINGS FROM 3D PRODUCT MODEL

摘要

Classification drawings have traditionally been developed in 2D software (e.g. AutoCAD) but separate applications are used for the development of a 3D design and engineering model. This results in duplicate effort, rework and error. To try to solve this problem, several shipbuilding specific software packages now can generate class approval drawings from the 3D model. However, these programs lack the detailing capabilities offered by AutoCAD so in practice, AutoCAD is still used as well. Thus, the problem with duplicate effort remains and is compounded as changes occur because the drawings are disconnected from the 3D model. This paper discusses a solution to the above industry challenge which consists of a new product from SSI called MarineDrafting. SSI MarineDrafting allows standard 2D AutoCAD drawings to be automatically generated from the 3D ShipConstructor model according to specific class rules and shipyard standards while remaining linked to the 3D model as changes occur.
