Hull Structure is the core of the CADMATIC Hull system. It is
used for 3D modeling of the hull structure from the basic
design up to the detailed and production engineering of hull
blocks, assemblies, panels and parts. It is available in two
different packages, Detail and Basic Design.
Hull Structure Detail Design
Hull Structure Detail Design (HSD2) seat overview
The Hull Structure Detail Design consists of the following modules:

- 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,
Fore peak section sheet drawing
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.

Hull Structure Detail Design
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, General Arrangement made with standard 2D drafting functions
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 subcategories. Hull 2D Library offers an automated
'List Generator', a smart feature that enables the
engineer to generate an inventory list of the Safety Plan made with Hull 2D Library
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 builtin 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 Production output examples
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 Hull Work Preparation Manager
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
Generated 2D shell view
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 oneto-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
Importing IGES hull shape data
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.
