3D Hull Engineering


Hull Structure is the core of the Cadmatic Hull system. It is used for 3D modelling of the hull structure from basic design up to detailed design and production engineering of hull blocks, assemblies, panels and parts.

Hull structure

The Hull Structure module distinguishes itself from other CAD/CAE/CAM systems in that it is extremely fast and easy to use. The intuitive user interface guides the hull designer with maximum assistance while creating structural components such as decks, bulk-heads, stiffeners, shell frames, girders, flanges, brackets etc.

Hull structures are stored topologically, which means that the relation between structural components and the hull shape are maintained, thereby allowing for fast and easy modifications to be made. The effects of modifications on a topological structure are automatically carried through to the related structural components. As such information can be re-used quickly without doing rework.

Rule-based engineering is another strong feature that assists the engineer e.g. in picking the correct bracket sizes (flanged or not) automatically according to specific Class Rules.

The module also supports a hull library mechanism to retrieve and store any kind of structure including its topological properties. Piping and outfitting components can be made visible during the 3D modelling of the hull structure.

The Hull Structure module includes powerful copy functions, parametric definition of yard standards and many automatic mechanisms such as part and panel numbering, marking lines,standard bracket selection, part coding etc. This does away with many of the hull designer’s daily worries and routine tasks.

The project library used by the Hull Structure module consists of a collection of the necessary yard standards for cut outs, profile end shapes, stiffener types, brackets, holes and other structural entities. In addition to the yard related standards, software settings and project specific parameters are also stored and maintained in the project library.
