As systems for computer-aided design and production of mechanical parts have developed there has arisen a need for techniques for the comprehensive description of the desired part, including its three-dimensional shape. The creation and manipulation of shapes is generally known as Geometric Modellin

The capabilities of current solid modelling systems are limited by the available representation schemes, geometric coverage, and types of operations allowed within a modelling system. Most of today's modellers can hardly do anything beyond graphic display and mass property calculation. Modelling sys
## Abstract A simple alternative way to position dielectric materials in the finiteβdifference timeβdomain (FDTD) Yee cell grid is proposed. Planeβwave illuminated spheres are used as examples to study the performance of the alternative method compared to the standard FDTD method. Although the perf
This paper describes a method for the recognition of the semantics of parts (features) of a component from a pure geometric representation. It is suitable for verifying product life-cycle requirements from the early stages of the design process. The proposed method is appropriate to analyse B-rep ge
