CAD/CAM _JVIultiSurf's reportedly precise control of complex shapes derives from the program's Relational Geometry framework. According to AeroHydro, this framework allows the designer to capture a wide variety of relationships while building a design — relationships which come in handy as the model is updated, because MultiSurf then updates the other elements of the design automatically. MultiSurf is not a NURBS (Non- Uniform Rational B-Spline)-based program, but it does support NURBS as one of 20 supported surface types. Those with Internet connections and World Wide Web browsing software can download a fully- functional version of MultiSurf (stripped only of its file-exporting capabilities) from AeroHydro's site on the Web; the "address" — URL, or Uniform Resource Locator — is http://www.netins.net/showcase/ aerohydr/msdemo.html.

We have a wealth of experience with all manner of vessel types for both newbuilding and conversion work. We use the STEERBEAR and TRIBON systems with which we have more than 25 years experience Steel Cad AB is currently providing expert design support to National Steel and Shipbuilding Company (NASSCO), the first US shipyard to fully adopt the KCS/TRIBON system. NASSCO is using the TRIBON Hull Application in its Sealift New Construction program, to design the first of a class of 290 m Panamax RO/ROs for the US Navy. Steel Cad engineers have provided NASSCO with detail design of hull module structure, shell development, fairing and nesting. This support has also included user training in the TRIBON system. " Steel Cad has made a major contribution to our implementation of this new system. Their expertise has provided us with a strong user base as we come up to speed with the TRIBON system says NASSCO. William B. Hale mm With the most up to date computers and software we have the know-how and the equipment. Call us today to see how we can help you with your project.

An initial group of 15 users was trained for all disciplines covered by TRIBON, including hull, outfitting, mechani- cal and electrical. The first task for which TRIBON was employed was the lengthening of a containership, a task which required application of all disci- plines the program covers. Re- portedly, the project was very suc- cessful and TRIBON helped the project team reduce excess amounts of steel.

The FORAN system is not unfa- miliar to PAL, which in 1982 was licensed to use version 10 of the system. The program was devel- oped by Senermar, the Spanish firm of naval architects. Implementation of version 30 will be carried out at the Surabaya yard, but part of the general design modules will also be implemented at the company's offices in Jakarta. The FORAN system is licensed for use in 121 shipyards in 21 coun- tries worldwide.

The software automates the conventional pro- peller drafting process. With Pro- pellerSoft, the designer can report- edly create high-quality two- or three-dimensional propeller draw- ings automatically. By clicking a mouse, the designer can obtain laser-quality drawings and infor- mation such as blade volume, hub volume, and propeller moment of inertia. The program was developed by registered professional engineers with hands-on naval architectural and marine engineering experi- ence. The independent file struc- ture of blade, foil, hub and nozzle (duct) used by the software not only offers an easy way of electron- ic storing and cataloguing of pro- peller designs, but also reportedly makes creating new variations of propellers faster and easier. PropellerSoft can save 3-D pro- peller models in .DXF format for exporting into other CAD pro- grams. Seastar says PropellerSoft can also be used as a pre-processor for lifting-surface or finite-element analysis programs.
