No such thing as a free lunch? How about getting free help with your CAD, CAM, or CAE issues? a website that claims it provides independent and objective information for 3-D CAD users, administrators, managers, and enthusiasts. Editor and founder Don Lacourse, former editor of Cadalyst magazine, brings his 30 years of experience in the industry to bear, scouring the Web for information along with developer- and reader-submitted data. The site was developed by eDocHelp.To get more news about cad tips and tricks, you can visit shine news official website.

Companies such as Hewlett-Packard, IBM, Tyco, Ford, GM, Delphi, and Gillette are current users of the site, which offers tips for specific packages including AutoCAD, SolidWorks, Catia, and most major CAD packages. Subjects range from curve and surface modeling and FEA to outputting STL files for rapid prototyping and CNC. Suggested for those considering a move from 2-D to 3-D, the site also caters to advanced users.  Says Lacourse, ?By necessity, most companies today have multiple 3-D CAD systems in production, and their users are spending countless hours online searching for helpful information on those systems. [The site] currently provides indexed access to application-specific tips for 15 different 3-D CAD systems with more being added with each release.

Compared with other high-heat materials, such as polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), Sabic’s Elcres polycarbonate copolymer–based HTV150A films reportedly can reduce dissipation losses by as much as 40% when exposed to temperatures reaching 150°C and frequencies up to 100 kHz. The material has already proven its mettle in thin-wall capacitor films.

Lower dissipation losses in Elcres HTV150A dielectric films can reduce internal heat generation, increase operating efficiency, and stabilize hot spot temperatures, giving engineers greater flexibility in designing capacitors. Lower losses in these films are expected to translate into reduced dissipation losses in capacitors.

“In developing Elcres HTV150A films, Sabic researchers drew upon their deep understanding of how polymers respond to thermal and electrical stress fields,” said Ed Kung, senior manager, Resin Design and Incubation. “They selected material compositions with mild dissipation mechanisms in the temperature and frequency ranges of interest and have achieved impressive results. As customers design new inverter systems and adopt next-gen silicon carbide power modules, lower dissipation losses at higher operating temperatures and frequencies can help drive success.
