In this paper, we explore several extensions to surface pasting. In particular, using the task of modelling a ferret as a driving force, we improved the user interface for cylindrical pasting; we looked at methods for reducing the distortion of pasted features; and we created a method for pasting trimmed features to allow for features that do not have the rectilinear shape of standard pasting.

Binary Optics: Binary (diffractive) optics uses computer-aided design (CAD) tools and verylarge-scale-integration (VLSI) electronic circuit manufacturing technology to create novel optical devices and to provide design freedom and new materials choices for optical elements. When combined with conventional (refractive) optical lens systems, binary optical systems cannot only provide athermalizat...

This paper presents news problems linked to the increasing use of virtual spaces in the building of new types of manufacturing what is currently called Virtual Manufacturing (VM). VM has many consequences in the activity of industrial companies whatever be size, economic sector or geographical area. Particular attention is paid on virtual spaces, manufacturing and collaboration, skills matrix a...

In this paper, we present a method for estimating local thickness distribution in finite element models, applied to injection molded and cast engineering parts. This method features considerable improved performance compared to two previously proposed approaches, and has been validated against thickness measured by different human operators. We also demonstrate that the use of this method for a...
