[accordion-item title=”Discussions +” state=closed]
- Discuss surfacing principals and prepare users for the basics (people come from many backgrounds have used surfacing for years but never really understood the basics).
- Discuss A-Class surface modeling and evaluation techniques involving various analysis and visualization techniques to the the math behind 3d curve surfaces. Discuss the basic calculus behind that curves and surfaces.
- Discuss the difference of using 3 degree vs 5 or 7 degree curves for building geometry. Discuss Algebra and Calculus of basic spine math and compare y=x^5 spine geometry to multi knot y=x^3 geometry.
- Compare Class A modeling in NX to tools such as AutoDesk Alias AutoStudio & Rhino3d.
- Compare G2 to G3 Continuity and discuss the Calculus behind the ideas.
- Discuss modeling technique and robust building efforts for more modifiable part models. Changes can be made hours before sending models for tooling.
- Discuss import geometry and techniques on managing external import data such as Alias or Rhino data in a product engineering environment.
- Compare to engineering teams remodeling the designer import geometry and discuss techniques associated to handing capturing the integrity (from the designers perspective) of the designer import geometry in an associative modifiable parametric model.
- Discuss Changing poles defining points and manipulating Surface Edit geometry.

Design Engine course presentations and examples involve some 35 specific example models to help participants utilize surface modeling techniques in Unigraphics NX. One example is to create a stapler using WAVE link functions (top-down design) where all the geometry works together to formulate the product and the participant is required not only to model the geometry but make significant design changes to the form in under 10 minutes. As geometry fails, the participant is shown valuable tools for managing parent child relationships. In the end the changes take longer than 10 minutes, however if done over the changes can occur much smoother time frame in effect challenging the participants to model the original form more carefully.
For example one project for making modifications for example to an 18” aircraft seat to a 24” aircraft seat using equations and parameters without remodeling the geometry.
