Hull Structure Detail Design (HSD2) seat overview The Hull Structure Detail Design consists of the following modules:

- Hull Structure - Hull Drafting - Hull 2D Library - Production Information - Seams & Butts, - Shell Views - Hullshape Import Manager - 2D eXchanger - 3D Export Manager - Integration

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, bulkheads, stiffeners, shell frames, girders, flanges, brackets etc. Hull structures are stored topologically, meaning that relations between structural components and relations with the hull shape allow fast and easy modifications. The effects of modifications on a topological structure are automatically carried through to the related structural components allowing fast and easy re-use of information 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 their topological properties. Piping and outfitting components can be made visible during the 3D modeling 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. taking away 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 all 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.

Besides 3D modeling, the Hull Structure module contains full 2D drafting functionality to complete the views of the 3D model, create details and any kind of sheet drawing.

Hull Drafting With this module, which is also part of the Hull Structure module, a wide range of structural drawings can be produced varying from classification drawings, construction plans, section drawings up to workshop drawings. The drawings are linked to the 3D model and updated automatically according to any changes, thereby offering the highest level of consistency. The module offers flexible tools such as Snap, Insert, Select, Trim, Extend, Cut, Copy, Paste, Undo, Redo, Properties and manipulate functions such as: shift, rotate, resize, mirror, duplicate and move. This enables full control over the drafting entities: Line, Arc, Ellipse, Rectangle, Spline, Hatch, Dash, Symbols, Fonts, Dimension and Annotations. The drafting method is modern, like AutoCAD® and uses Dynamic Input, popup menus, hotkeys, function keys, function dependent options and recently used functions.

Hull 2D Library Hull 2D offers a specific and dedicated 2D drafting functionality to create and maintain general drawings and plans such as general arrangement, main section, construction plan, safety plan, manholes and doors plan as well as 2D accommodation drawings. With Hull 2D Library the user has access to a full library driven interface for adding user-defined symbols to the drawing and automatically generating piece part lists on the drawing. It offers a complete user definable 2D library structure to create, store and retrieve 2D symbols. The library can be created according to the end user's definition of categories and sub-categories. Hull 2D Library offers an automated 'List Generator', a smart feature that enables the engineer to generate an inventory list of the applied Hull 2D Library symbols on the drawing automatically and quickly. Hull 2D Library is an ideal feature for generating safety plans (multi lingual) and i.e. deck layout drawings.

Production Information For production engineering a fully equipped set of work preparation tools is embedded in the Hull Structure module. This ensures that production receives all the required information such as welding details, part lists, weight and CoG, profile lists, profile nesting, profile sketches, shell frame bending information, part geometry for nesting etc. The information is directly derived from the 3D model with the built-in Report Generator. The user is able to define his own report layout and to perform "Action on Reports" to query the 3D model for various production and logistic data. When used together with the Hull Work Preparation Manager (see separate description), 3D work breakdown sketches and 2D+3D combination sketches can be generated automatically for use at the workshop floor. Hull Work Preparation Manager (WPM) The Hull Work Preparation Manager is part of the Hull Structure module and streamlines the information flow between, engineering, planning, work preparation and the workshop. Hull WPM speeds up the process of work preparation significantly, and thus shortens the throughput of the ships' several assembly stages. The WPM functionality is embedded in the Hull Structure module. WPM provides a set of unique tools for automatic detecting and assigning numbers to assemblies, subassemblies, panels and parts. Parts such as profiles, brackets and collar plates are automatically assigned to the correct panel. With this functionality the complete work breakdown structure of a hull block can therefore be determined automatically by the software. The depth of the work breakdown structure can be freely defined up to sixteen levels. In addition, each individual part can automatically receive a workshop 'process code' and 'job number', based on the part's properties and work process, such as flanging, cutting, bending, beveling etc. All these features give the shipyard very flexible possibilities for generating the desired work breakdown structure automatically. With the Hull Work Preparation Manager the user is able to control the complete work breakdown structure of a hull block easily and quickly. The use of the Hull WPM is very simple and straightforward. Once the work breakdown structure has been generated by the software, the user can easily manipulate

its structure by dragging and dropping items on the computer screen, rename assemblies, panels and parts and also create new ones. The Hull WPM is operated like Windows Explorer and offers 3D assembly animation features. Hull WPM is available as an integrated part of the Hull Structure module and as a standalone module, the so called Hull Viewer Work Preparation Manager. The manipulation of the work breakdown structure with the integrated Hull Viewer is directly processed by the 3D Hull database. The standalone version of the Hull WPM has the advantage that it does not require a full CADMATIC Hull license. It is intended to be used between project partners, such as engineering offices and shipyards, or between the engineering and work preparation department at the shipyard. A practical example of using the Hull Work Preparation Manager is where the work preparation department determines the actual work breakdown structure based on the 3D Hull model. The modified logistic information in the 3D model is returned to the engineering office and merged into the Hull database, after which the engineering office delivers the production information in the desired format to the shipyard's production.

Seams & Butts With the Seams & Butts module the user has the possibility to add and modify seams and butts to the hull shape database. The user projects the lines, which are defined in one of the three views (top, aft and side) on the ship's hull shape. Besides the projection of the lines, the seams and butts can also be interpolated on the ship's hull shape database. The module offers various copy, paste and move functions for flexible working. The Seams & Butts module requires the Shell Views module.

Shell Views With this module the hull designer can produce 2D shell views drawings in four different views. The module generates the view according to the "Area" (box) of that part of the ship that he wants to see. The view includes all available seams and butts together with the existing hull structure in the 3D hull model such as decks, girders, frames, etc. The views that can be generated are aft, side, top and spatial views. After the view is generated from the 3D hull model the hull designer can determine various kinds of information and add this as attributes to the view. The module also offers several functions for dimensioning, positioning stiffener information and adding 2D construction lines in case all information is not available in the 3D hull model yet. The shell (expansion) view is stored and treated in the same flexible way as inserting views in a drawing with the other CADMATIC Hull modules.

Hullshape Import manager With the Hullshape Import Manager it is possible to import surface based hull shape models directly into CADMATIC, based on different independent file formats. Existing features, such as instant access to a NAPA shape database or importing wire frame data, are also available. The module supports the import of the following file formats: IGES (*.igs, *.iges), Rhino 3DM (*.3dm), NAPA (*.db), ACIS (*.sat) and AutoCAD® (polygons only) (*.dxf).The imported surfaces and curves are divided into hull groups (or layers, they have a one-to-one relationship). Depending on the imported file format the layer assignment is (semi) automatic. After the surfaces and curves are assigned to the proper hull groups, the user defines the frame (coordinate) list. The hull shape is stored in the default CADMATIC Hull DataBase format which has the *.hdb extension. Other supported formats to store the shape data are IGES (*.igs, *.iges), ACIS (*.sat), 3D Dump (*.3dd), eBrowser Model (*.ebm) and Hull Viewer Model (*.hvm). The hull database is related to the inner construction (via so-called topology). When a revision of the hull shape database is loaded and activated, the modelled construction is recalculated according to the new hull shape. Merging additional surfaces and curves (in an existing hull database) is possible from different file formats. This, for instance, allows the shape of the hull and superstructure to be modelled with different software.

2D eXchanger Hull This module is used to import and export 2D views and 2D drawings from and to other drafting systems according to the AutoCAD® DXF and DWG formats.

3D Export Manager Hull This module is used to export 3D hull geometry to other 3D systems according to following formats: AutoCAD® DXF and DWG, IGES, SAT and Rhinoceros. For users who have the need to translate the 3D hull model into native AutoCAD® format, the Hull ARX plug in module for AutoCAD® is available. This module converts the 3D hull model into the AutoCAD® 3D workspace for further processing. Download the Hull ARX plug in from www.cadmatic.com.

Integration This integration module reads into Plant Modeller module the CADMATIC 3D hull structure and uses that as original, true components inside Plant Modeller module. Modifications made by the piping designer (such as holes for penetrations etc.) are updated automatically and in real time for the CADMATIC hull designer’s acceptance. After acceptance the holes will be cut, or without acceptance only be powder marked. The Hull user is also able to see inside Hull Structure the 3D model created with Plant Modeller and to access the piping & outfitting component library to position 3D models inside the hull structure.
