Some 154 global standards make up the third and updated edition of the ISO handbook "Technical Drawings." The goal of ISO/TC 10, the technical committee that drafted most of the standards, is to enable a drawing to be interpreted correctly in any country, regardless of language differences. Among the handbook's contents are standards for dimensioning, tolerancing, microcopying, surface texture, graphical symbols, and drawing equipment. A separate section deals with mechanical engineering drawings. You can buy the handbook, which comes in two volumes, from any national member of ISO or from the ISO Central Secretariat at 1 rue de Varembe, CH-1211 Geneva 20.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
