  • 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.

  • Generating Sample Looks for Geometric Objects in a Visual Design Language
    Generating sample looks for geometric objects in a visual design language Omid Banyasad Philip T. Cox Technical Report CS-2008-04 March 17, 2008 Faculty of Computer Science 6050 University Ave., Halifax, Nova Scotia, B3H 1W5, Canada Generating sample looks for geometric objects in a visual design language Omid Banyasad Philip T. Cox [email protected] [email protected] IBM Software Group Faculty of Computer Science, Ottawa Lab Dalhousie University Ottawa, Ontario, Canada Halifax, Nova Scotia, Canada Abstract. A major application of visualisation is to the design of structured objects such as buildings, machinery and electronic circuits, as in Computer- Aided Design (CAD) systems. Complex designs are frequently parameterised so that they represent families of objects rather than single artifacts, and building them requires design environments that support both the concrete visualisation and manipulation of components, and the abstract specification of how they are related. CAD systems usually separate these two aspects, providing the abstract programming capability via a textual programming language grafted on to a 3D object editor and solid modeler. A recently proposed design language merges these two activities by embedding representations of solid objects in a visual logic programming language. A prac- tical issue that arises is how to automatically generate a “sample look”, a reason- able representation for a parameterised object which can be displayed during ex- ecution (assembly) of a design. We present a solution to this problem based on “factoring”, which separates the constraints on a solid object from its geometric properties. 1 Introduction The work reported here is part of a project originally motivated by the hypothesis that since both geometric objects and some of the operations used for combining them can have concrete visual representations, a visual design environment that provides programming capabilities via manipula- tion of such representations would be a powerful tool for creating parame- terised objects.

Starting from the year 2015 it is a requirement to use BIM even in tenders. In order to meet these requirements WSP developed their own product Open VR - a data platform for visualization, communication, planning, designing as well as a tool for documentation of new and existing environments. Geotechnical analysis is an important part in most of the projects and affects the economy, the projects timeframes and further projects design greatly. Availability of good quality basic data is a requirement to succeed in a project. Inaccurate and late delivered rock and soil 3D models cause the problems at the design stage. A completely or partially automated process for creating 3D soil models using geotechnical database and models presentation in Open VR would provide both economic benefits and reduce the amount of repetitive work in the CAD environment. One of the biggest issues is to combine data coming from different sources and therefore clear standards on how different fields of technology should prepare their information are needed.
