Autoship Systems Corporation's

Total CAD/CAM Solution for Ship Design and Building

Autoship Systems Corp. (ASC) has initiated a new 'total system' approach to

CAD/CAM software for shipyards, aim- ing to eliminate what it terms the most expensive CAD/CAM inefficiencies within the design-to-manufacture process: data exchange and interface discontinuities between specialized products (and the additional training and maintenance costs that result). ASC sought to achieve these goals through designed interoperability, with the over- all system bringing a shipyard's major design and construction phases into the same data chain, and the interface remains familiar through each stage of the process.

Autoship's total solution includes five

ASC products and software options from two partnered companies. While some of the product names are familiar, four of the Autoship products are either brand new or so re-engineered that they can be considered brand-new:

The Autostructure 1.1 Group (Released 1st Quarter 2002)

Autostructure performs internal struc- tural modeling tasks. Designed to sup- port many networked engineers working simultaneously on single or multiple projects, its data base capacity and response time provide well for even the largest shipyard. It starts with project files generated in Autoship and Auto- plate (plate design and structural model- ing can proceed in parallel). Autostruc- ture aims to simplify design tasks by providing specialized dialogues, excel- lent graphical methods, and advanced regeneration based on automatic track- ing of part dependencies and interrela- tionships. The Autostructure group con- sists of three associated programs:

Autostructure itself, Project Manager, and Report Manager. Project Manager provides database management func- tions (project creation, archiving, back- up and access control). Report Manager provides flexible and customized report generation.

Autoship 8.1 (Released 1st Quarter 2002)

Version 8.1 retains all that ASC has learned from 20 years of developing this

CAD/CAM product, yet has been re- engineered to provide the foundation for a modern and integrated CAD/CAM suite for ship design. The many addi- tions and enhancements to the user interface include the Navigator (a float- ing window in which the project is dis- played as a tree), and the OpenGL View- er developed for Autostructure. Dynam- ic display is included when editing curves, and immediate updating is avail-

July, 2002 able when editing control point weight.

Centred on a NURBS-based mathemati- cal engine, Autoship displays models in four views — three axes and a rotatable 3-D view. Autoship works with several types of points, curves and surfaces, including developable surfaces. A spe- cial feature allows surfaces to be con- structed from an offsets table. Editing is accomplished through control points, edit points, scaling, translation, rotation or shearing. Models can be exported as
