Volumetric Modeling in Cao for the Design of Automobile Parts

Abstract
The research offices and the automobile systems offices which
became highly competitive in the areas of computerized design, from
design and manufacturing of defined parts beginning with surface
areas, have now discovered potentials for informational systems
suggesting creative design and production control.
In the same fashion, the power of the calculation units and the
increasing performances of graphics, at constantly diminishing
costs, have allowed planning for use of more complex computers.
Thus, the systems designers of CFAO were able to set up third
generation products: after the "2 dimensions" then the
"3 dimensions" surface, the "3 dimension"
volumetric integrating complex left sides has been put into
use.
Relying on examples, one will show how in the automotive
industry these products allow the following: - better management of
space that is useful during architectural study of a subassembly:
clearance under the hood, installation of driving gears and control
parts in the dashboard, arrangement of the trunk, etc... -
optimization of mechanical parts issued from forge or foundry
"crudes," thanks to a calculated simplified model by the
method of finished parts, -description of body parts in plastic or,
functional and rigid interior forms border the exterior forms
issued from the study of the stylist to constitute a complex space,
- help in modeling and setting up of robots.
The choice of the defining mode of the parts: "elementary
solids," "facetization of surfaces" or "spaces
with complex sides" is directly linked to CFAO applications
under the office of research: in the automobile the necessity of an
integration between research offices and sectors of tools
manufacturing required us to be directed to the third.
