CAD for VEX Robotics
CAD for VEX Robotics (updated 7/23/20) The question of CAD comes up from time to time, so here is some information and sources you can use to help you and your students get started with CAD. “COMPUTER AIDED DESIGN” OR “COMPUTER AIDED DOCUMENTATION”? First off, the nature of VEX in general, is a highly versatile prototyping system, and this leads to “tinkerbots” (for good or bad, how many robots are truly planned out down to the specific parts prior to building?). The team that actually uses CAD for design (that is, CAD is done before building), will usually be an advanced high school team, juniors or seniors (and VEX-U teams, of course), and they will still likely use CAD only for preliminary design, then future mods and improvements will be tinkered onto the original design. The exception is 3d printed parts (U-teams only, for now) which obviously have to be designed in CAD. I will say that I’m seeing an encouraging trend that more students are looking to CAD design than in the past. One thing that has helped is that computers don’t need to be so powerful and expensive to run some of the newer CAD software…especially OnShape. Here’s some reality: most VEX people look at CAD to document their design and create neat looking renderings of their robots. If you don't have the time to learn CAD, I suggest taking pictures. Seriously though, CAD stands for Computer Aided Design, not Computer Aided Documentation. It takes time to learn, which is why community colleges have 2-year degrees in CAD, or you can take weeks of training (paid for by your employer, of course). -

19 Siemens PLM Software
Chapter 19 Siemens PLM Software (Unigraphics)1 Author’s note: As discussed below, this organization has had a multitude of different names over the years. Many still refer to it simply as UGS and, although that name is no longer formally used, I have used it throughout this chapter. McDonnell Douglas Automation In order to understand how today’s Siemens PLM Software organization and the Unigraphics software evolved one has to go back to an organization in Saint Louis, Missouri called McAuto (McDonnell Automation Company), a subsidiary of the McDonnell Aircraft Corporation. The aircraft industry was one of the first users of computer systems for engineering design and analysis and McDonnell was very proactive in this endeavor starting in the late 1950s. Its first NC production part was manufactured in 1958 and computers were used to help layout aircraft the following year. In 1960 McDonnell decided to utilize this experience and enter the computer services business. Its McAuto subsidiary was established that year with 258 employees and $7 million in computer hardware. Fifteen years later, McAuto had become one of the largest computer services organizations in the world with over 3,500 employees and a computer infrastructure worth over $170 million. It continued to grow for the next decade, reaching over $1 billion in revenue and 14,000 employees by 1985. Its largest single customer during of this period was the military aircraft design group of its own parent company. A significant project during the 1960s and 1970s was the development of an in- house CAD/CAM system to support McDonnell engineering. -
Development of a Coupling Approach for Multi-Physics Analyses of Fusion Reactors
Development of a coupling approach for multi-physics analyses of fusion reactors Zur Erlangung des akademischen Grades eines Doktors der Ingenieurwissenschaften (Dr.-Ing.) bei der Fakultat¨ fur¨ Maschinenbau des Karlsruher Instituts fur¨ Technologie (KIT) genehmigte DISSERTATION von Yuefeng Qiu Datum der mundlichen¨ Prufung:¨ 12. 05. 2016 Referent: Prof. Dr. Stieglitz Korreferent: Prof. Dr. Moslang¨ This document is licensed under the Creative Commons Attribution – Share Alike 3.0 DE License (CC BY-SA 3.0 DE): http://creativecommons.org/licenses/by-sa/3.0/de/ Abstract Fusion reactors are complex systems which are built of many complex components and sub-systems with irregular geometries. Their design involves many interdependent multi- physics problems which require coupled neutronic, thermal hydraulic (TH) and structural mechanical (SM) analyses. In this work, an integrated system has been developed to achieve coupled multi-physics analyses of complex fusion reactor systems. An advanced Monte Carlo (MC) modeling approach has been first developed for converting complex models to MC models with hybrid constructive solid and unstructured mesh geometries. A Tessellation-Tetrahedralization approach has been proposed for generating accurate and efficient unstructured meshes for describing MC models. For coupled multi-physics analyses, a high-fidelity coupling approach has been developed for the physical conservative data mapping from MC meshes to TH and SM meshes. Interfaces have been implemented for the MC codes MCNP5/6, TRIPOLI-4 and Geant4, the CFD codes CFX and Fluent, and the FE analysis platform ANSYS Workbench. Furthermore, these approaches have been implemented and integrated into the SALOME simulation platform. Therefore, a coupling system has been developed, which covers the entire analysis cycle of CAD design, neutronic, TH and SM analyses. -

Chapter 18 Solidworks
Chapter 18 SolidWorks As much as any company in the CAD industry, SolidWorks was inspired by the vision of a single individual, Jon Hirschtick. He received both a BS and an MS degree in mechanical engineering from MIT in 1983 and subsequently worked at the MIT CAD Laboratory under Dr. David Gossard. Hirschtick had a strong entrepreneurial streak in him from an early age including a period as a self-employed magician during high school. While working at the CAD Laboratory, he enrolled in an entrepreneurship class in 1987 where he teamed up with Axel Bichara to write a business plan for a new CAD software company they called Premise. Bichara was a graduate student from Germany who was also working at the CAD Laboratory at the time.1 The class business plan for Premise was submitted in mid-May, 1987 and in a little over a month the two founders had $1.5 million in venture funding from Harvard Management Company. It was no surprise that the company set up shop in Cambridge. Figure 18.1 Jon Hirschtick2 Premise’s initial software product, DesignView, was a two-dimension conceptual design tool that ran on IBM-compatible PCs and interfaced with Microsoft software packages such as Word and Excel. Users could sketch geometry, assign constraints and define dimensional relationships. If a dimension changed, the design would adapt to this new information. Since it could be interfaced to Excel, spreadsheets could be used to 1 Bygrave, William D. and D’Heilly, Dan – editors, The Portable MBA in Entrepreneurship Case Studies, Pg. -
21 Miscellaneous Companies
Chapter 21 Miscellaneous Companies Space restrictions simply do not permit me to go into the depth of detail I would like on every company that participated in the early days of the CAD industry nor cover numerous in-house systems developed at major automobile and aerospace companies. Readers will have to be satisfied with the brief descriptions included in this chapter and even then, I have only been able to cover what I consider to be the companies that had the biggest impact. There are hundreds if not thousands of companies that at one time marketed engineering design software. Some of the companies described in this chapter offered just software while other provided both hardware and software. While many have changed names, I have decided to list them alphabetically based upon the name they are best been known by along with earlier and subsequent name changes. Adra Systems (Matrix One) Adra Systems was founded in Lowell, Massachusetts in July 1983 by William Mason, who had been at Applicon from 1973 to 1983, most recently as vice president of operations, James Stenzel, who had been vice president of engineering at Hastech, Inc., and Peter Stoupas, who had earlier been a regional sales manager at Adage and had also worked for Applicon. Mason became the president and CEO, Stenzel the vice president of product development and Stoupas the vice president of marketing. Between 1983 and 1986, the company raised $11.6 million of venture funding from a number of firms including American Research & Development, the company that also provided the initial funding for Digital Equipment Corporation. -
COMPIT Paper
History and Evolution of Shipbuilding Oriented CAD Tools Rodrigo Perez Fernandez, SENER, Madrid/Spain, [email protected] Carlos Gonzalez Lopez, SENER, Madrid/Spain, [email protected] Abstract This paper traces the history of ship design since Roman times, when ship designers began to use curves for drawing frames, through the Venetian techniques (XIII-XVI centuries) reusing templates, to the most modern methods for ship design with FORAN. The FORAN software offers a comprehensive process for the design and construction of ships, offshore platforms and submarines, with the help of computers. It was conceived as an advanced engineering technique for improving the design and reducing the construction period of a vessel. This paper traces the history of this CAD system, since its organization was differentiated into two stages: design (modules from F.1 to F.7) and production (F.8 to F.22); until the recent advances in integration with Product Lifecycle Managements, Virtual Reality and the near future where all the ship product information will be accessible in electronic devices, allowing paper-less design. 1. Introduction to CAD systems Computer-Aided Design (CAD) Systems help engineers and designers in various industries, designing and building 3D models of airplanes, cars, bridges, digital cameras ... and of course, ships, submarines and floating structures. There are other acronyms that are usually accompanying the acronym CAD, such as Computer-Aided Manufacturing (CAM), Computer-Aided Engineering (CAE), and Computer Integrated Manufacturing (CIM), including instructions to Computer Numerical Control (CNC) ma- chines. One could claim that these CAD/CAM/CAE Systems had their origin around the year 350 BC, with the mathematician Euclid of Alexandria. -
