2. Intelligent Methods of Three-Dimensional Modeling in CAD

Creating and editing engineering data

History-based modeling has been the dominant CAD technology for many years; it is still widely used. Last years history-free (or direct) modeling becomes more robust and useful, and now CAD users can choose between two very viable and very different technologies. This workgroup will be a place for discussion how this choice impacts the intellectual property and product development process of customers.

Discussion topics:

• Parametric modeling of surfaces and solids
• Comparative analysis of history-based parametric modeling with direct geometry editing: advantages and drawbacks of each approach
• What direct editing tools are offered in mainstream MCAD
• How to keep design intent in history-free environment
• Comparison of geometric modeling kernels
• What file format will be used for CAD data exchange in 2050?
