Title:
DATA EXCHANGE BETWEEN COMPUTER AIDED DESIGN SYSTEMS
Document Type and Number:
WIPO Patent Application WO2001018696
Kind Code:
A3
Abstract:
A method and apparatus for mechanical data exchange between parametric computer aided design systems ("CAD"). According to an embodiment, computer-implemented methods, techniques and structures are employed to extract parametric specification data from a source CAD file and create a second parametric-based CAD file for a different CAD system. In one embodiment, an intermediate data structure is utilized. An objective is creation of a second parametric-based CAD file that preserves design intent of the parametric-based source CAD file.
