CATIA V5- Class A Surfacing

CATIA V5- Class A Surfacing

Class A surface modelers are called digital sculptors for a reason: the Class A surface represents the absolute peak of styling for freeform surfaces. For this reason, the Class A technique is used to design automobiles, high-end products like mobile phones, and aerospace craft, where the shapes must be of the highest quality. This course introduces the concepts behind Class A surfacing, including an explanation of key terms and their roots in shipbuilding history. You also learn the fundamentals of Class A surfacing design—from deriving curves to creating mesh surfaces—and find out how to implement these techniques in CATIA V5, a leading CAD platform. Instructor Steven Marjieh also shows how to assemble the final form, and perform an analysis to ensure your designs meet the original engineering and styling intents.

Topics include:

  • What is Class A surfacing?
  • Primary, secondary, and tertiary geometry
  • CAD tools and options
  • Deriving curves off existing geometry
  • Extruding and revolving advanced geometry
  • Creating mesh surfaces
  • Creating offsets
  • Joining elements
  • Creating and extending slabs
  • Creating tangent curves
  • Making tertiary blend surfaces
  • Removing excess material and joining the final elements
  • Measuring and modifying the final shape
