Class-A Surfacing Essentials in CATIA: The Standards Behind Automotive Body Styling

Creating Flawless Aesthetic Exterior Car Panels

In luxury automotive styling, panel surfaces must show perfectly smooth light reflections without visual ripples or sudden highlight breaks. Class-A surfacing ensures surfaces maintain curvature continuity across panel boundaries.

The Geometric Hierarchy: G0 Through G3 Continuity

Surfacing specialists control the mathematical curves that define complex exterior styling.

  • G0 (Point Continuity): Surfaces touch along an edge, creating a sharp crease or seam.
  • G1 (Tangent Continuity): Shared tangent vectors smooth the seam, though surface curvature changes abruptly.
  • G2 (Curvature Continuity): Matched radius curves create smooth highlight reflections across body seams.
  • G3 (Torsion Continuity): Curvature rate-of-change matches seamlessly across boundaries, producing showroom-grade body highlights.
