Solid Modelling and CAD Systems

This volume provides readers with an insight into the methods and problems associated with CAD systems. It bridges the gulf between users who are ignorant of how interfaces work and developers who create systems without understanding the needs of the users.

Solid Modelling and CAD Systems gives users an insight into the methods and problems associated with CAD systems. It acts as a bridge between users who learn interfaces without understanding how they work and developers who create systems without understanding the needs of the users.

The main feature of Solid Modelling and CAD Systems is a logical analysis of the techniques and basic solid modelling methods used in modern CAD systems. The book goes on to describe, among other subjects:

• two-dimensional shape definition methods,
• the command interface and graphics,
• databases and data exchange,
• early-phase design, and

• command files and command structures.
  Reading Solid Modelling and CAD Systems will help users understand the limitations of the techniques they are using and will enable practitioners to use CAD systems more efficiently. It is a valuable tool for designers, as well as for advanced undergraduate and postgraduate students. The exercises it contains allow readers to try out different aspects of the subject matter and the book also includes projects that can be used for teaching purposes.

  Enables practitioners to use CAD systems more efficiently Gives instructors a more thorough way of teaching students about CAD systems Includes a number of case studies Includes supplementary material: sn.pub/extras

  Autorentext
  Ian Stroud has worked with solid modelling since 1977 and has a number of unique insights into how CAD systems work, which are shared in this book. Ian Stroud started work in the first research group in boundary representation solid modelling, headed by Ian Braid. He was responsible for developing the first versions of many operations used in CAD systems today. In 1980 he moved to Sweden to continue work on generalising models, an idea of Professor Torsten Kjellberg. Ian Stroud was responsible for making the ideas work and developed many of the data structure elements, the basic techniques and system philosophy behind these. Techniques used in modern systems, such as thickening sheet models, shelling and wire-frame extrusion, originate from him. He has continued to look at different aspects of modelling which will help system users to be more efficient in their work when they eventually arrive in commercial systems. Ian Stroud is also knowledgeable about many other modelling aspects, such as features, which underpin efficient communication between application areas. He also teaches a course on Computer-Aided Engineering for Master's level students for which many of the exercises in this book were developed.
