CAD/CAM

Complete Vessel Structure Modeling and Part Nesting by Autoship

Autoship Systems Corporation (ASC) has developed a com- plete CAD/CAM suite to meet the CAD/CAM needs in marine vessel design and construction, including two key programs in the CAD/CAM suite: Autostructure 3.0 and Production

Manager 3.0. Autostructure and Production Manager are key components in the Autoship CAD/CAM suite, offering ship- yards complete solutions in structural design, pre-construction drawing preparation and part nesting.

Autostructure is used to create a 3D model of a vessel struc- ture and to output the parts of that model in CAD format. The

CAD representation can be used either to prepare construction drawings or for input to NC cutting processors. Autostructure utilizes an Autoship-generated hull and/or superstructure and can also include the shell plate information created in

Autoplate. (Autoship and Autoplate are programs in the

Autoship Systems CAD/CAM suite.

Autostructure was designed to allow parts to be created quickly and with minimal input. While there is a general work- flow. no set ways or sequences are forced upon the user. And since parts can be generated rapidly, mistakes can be quickly and easily remedied. Also, if a part is changed or moved.

Autostructure can update the surrounding structure.

Autostructure has an interface with the piping design system "AutoPLANT" by Bentley Systems Inc. Data exchange between the two programs allows for coordination of design between piping designers and structure designers, hence avoiding costly rework tin the vessel construction site.

All parts designed in Autostructure can be imported into

Production Manager for nesting and related processing.

Production Manager provides sheet and linear (extrusion, flat bar) nesting, part subdivision, weld shrinkage compensa- tion. stock definition, stock inventory and stock remnant man- agement.

Together. Autostructure and Production Manager provide complete control over vessel structure design and nesting, plus integration with third party piping. These components have completed the ASC CAD/CAM suite.

ARL Releases

ShipConstructor2005

Smart Hull module surfaces empower user creativity

Albacore Research Ltd (ARL) released ShipConstructor2005, the lat- est version of its AutoCAD-based 3-D product modeling software for the design and fabrication of complete ships and offshore structures.

ShipConstructor2005 was developed under AutoCAD20()5 with backwards compatibility to AutoCAD2004, pro- viding many new functions that arc designed to improve productivity, not only while operating the software, but also downstream in production and through integration of ShipConstructor with other business processes. "The last development cycle had been a very short one, with ShipConstructor2004 released in October 2003. We decided to move our 2005 release date to June in order to take advantage of function- al enhancements in Autodesk's spring release of AutoCAD2005," said Rolf

G. Oetter, Founder and President of

ARL.

With the introduction of the Hull module. ARL brings much of the func- tionality of the proven but so far stand- alone ShipCAM solution into

ShipConstructor, thus running inside of AutoCAD. Users will be able to open ShipCAM files, import 3DM (Rhino) and ICES (most hull design programs) files.

The Hull module's functionality pro- vides trim-able surfaces, stringer lay- outs. pin-jigs and inverse bending.

Plate expansion, including forming templates, accuracy control data and strain maps are also included.

Established ShipConstructor mod- ules (Manager, Structure. Pipe.

Penetrations, Equipment, HVAC) are boosted by numerous performance improvements to offer users more flex- ibility. fine-grain control and quicker functionality. Notable features of

ShipConstructor2005 include: Smart

Bill of Materials: Improved Database

Integration; and Pipe Module

Enhancements.
