Hull
Hull combines purpose-built shipbuilding specific surfacing technology and the simplicity of working inside of AutoCAD. This brings together the best of two worlds. It allows for easy and intuitive creation and manipulation of complex surface models while also allowing the freedom to use standard AutoCAD drafting techniques.
Hull provides powerful features such as surface-surface intersection, surface trimming, plate expansion, structural section definition, shell expansion, shell stringer definition, offset book printing, and pin jig drawing generation. The data designed in the external hull production model flows freely into the Structure product.

Structure
Structure offers rapid 3D production detailing of internal hull structure. It combines aspects of both associative and parametric 3D modeling but is tailored specifically to the design of ships and offshore structures. Accurate and intelligent 3D project models can be created very quickly utilizing a cross section of shipbuilding specific capability and native AutoCAD tools.

MarineDrafting
In a world of 3D design and manufacturing, many activities still need to be supported with 2D drawings during design and throughout the shipyard. Using shipyard standards, MarineDrafting allows the creation of 2D approval and workshop drawings directly from the 3D model. These drawings are created in AutoCAD DWG format and remain associatively linked to the 3D model as changes happen.
