The goal of this paper is to bring together the worlds of design and active databases. Design databases have to provide a powerful data model for complex structured design data as ...
In this paper we discuss how to reconstruct 3D models from multi-view engineering draws by employing human engineers' approaches. Human's `divide and conquer' inter...
Deformation of 3D shapes usually requires the use of a deformation tool. The freeform deformation technique requires the use of a lattice of control point for deforming an object....
This paper presents a method for three-dimensional surface flattening, which can be efficiently used in threedimensional computer aided garment design. First, facet model is used ...

A reasoning Boolean operation based CAD modeling approach applied to construct heterogeneous material objects is presented. This reasoning Boolean operation consists of a merging ...
Current modelling systems adequately support either modelling of parts or modelling of assemblies, whereas ideal modelling systems should adequately support both. To achieve this,...

A general discussion of the including approximation of a curve by a fat arc is given followed by an algorithm for constructing an including fat arc for a parametric Be
