Abstract In Solid Modeling, a boundary representation (b-rep) defines solids by their
bounding surfaces, providing an efficient volume description. Building on this …

In a factory with different kinds of spatial atmosphere (warehouses, corridors, small or large
workshops with varying sizes of obstacles and distribution patterns), the robot's generated …

With the advancements of 3D modeling software, the use of 3D CAD in mechanical product
design has become a standard practice. Methods and tools are continually being developed …

To perform a mechanical simulation of a component, its geometrical model usually needs to
be simplified in accordance with the hypotheses on its mechanical behaviour. Here, the …

Automatically detecting modifications between CAD models has many potential applications
in product development processes. Tracing modifications throughout the design and …

Being able to automatically mesh composite geometry is an important issue in the context of
CAD–FEA integration. In some specific contexts of this integration, such as using virtual …

The efficient, economical and often elegant transformation from a design schema to an
embodied design solution containing real components is essential for the commercial …
