CAD/CAM/CAE al modeling starts with 3-D sections that are imported from a hull fairing system.

With a single command, CAD-Link98 generates one 2-D drawing for each frame, girder or deck. CAD-Link also is designed to address many time consum- ing procedures in part production, with interference checking of parts to allow for easy identification and changing of intersecting parts.

Maestro Version 8.0 is loaded with new features, including composite pan- els, masses, acceleration and load bal- ancing in waves. The latter three fea- tures allow a complete and rigorous quasi-static modeling of dynamic loads, throughout the entire structure. Accord- ing to Nick Danese of Design Systems & Technologies, today's users of advanced CAD/CAM programs have a large part in future version develop- ments, crediting as much as 75 percent of functionality due to direct customer requests. "We think we are good pro- grammers, be we don't know everything about ship design," Danese conceded. "We have to ask our customers."

Design Systems & Technologies and

SPAR Associates recently demonstrat- ed new computer software, specifically the visual cost estimating system which links hull structure modeling with cost estimating. Developed by Proteus

Engineering and SPAR, the develop- ment is a real-time link between Mae- stro and EstiMATE, thereby transform- ing Maestro Modeler into a very rapid and effective cost-product modeler. The hull model allows rapid development of structural scantlings organized by ship zones and basic type of structural assemblies. The material cost estimates are developed using prices from a stan- dard parts library for plates and shapes.

A major contract with Halter Marine was recently signed by AeroHydro, a pioneer in CAD for boats and ships.

Halter purchased the MultiSurf,

MSDEV and MSPLEX to design new commercial marine vessels. The com- bined use of the technologies will reportedly help Halter create accurate lofting and NC machining, reduce scrap and accelerate the assembly process.

MultiSurf is AeroHydro's flagship product, and is an advanced 3-D surface modeler for marine applications. The technology is based on AeroHydro's patented relational geometry engine that allow complex models to be created and modified with precise and enduring relationships among parts. "Ship- builders face fierce global competition.

The use of leading-edge technology such as MultiSurf, MSDEV, and

MSPLEX is critical to enhancing engi- neering efficiency and product quality," said Bob Watkins, Halter's hull chief.

Autoship Systems Corporation

July, 1999 released a library of marine gear and equipment models. The models will help in the preliminary assessment of space available on deck, and to enhance the visual presentation of the vessel's design. This library is reportedly the first of its kind in the software design marketplace and will enhance the design tools available to Autoship users.

The models have been developed in the Autoship-hull design/surface model- ing program, and are native Autoship files (PR3).

The models are imported into the user's Autoship vessel definition. When making a presentation to an owner or an investor, the models will make the dif- ference providing a design looking very

Circle 259 on Reader Service Card realistic, convincing and professional.

The list of currently available models include: anchor, antenna, antenna radar, satcom antenna, 3 types of life boats, 3 types of rescue boats, 2 types of cranes, door, 2 types of hatches, 2 types of lad- ders, life raft, life ring, monitor, mooring bitt, mooring chock, navigation light, 3 types of propellers, rail, seat, stair,
