Lesson 2: Curves, Sections, Primitives, Surface Reconstruction, and Continuity

Section curves, silhouettes, feature lines, boundaries, curve fitting, and smoothing
Planes, cylinders, cones, spheres, extrusions, revolutions, and analytic primitives
Surface fitting, patch layout, swept, through-curve, bounded, fill, and studio surfaces
G0, G1, G2 continuity, matching, trimming, extending, sewing, and gap repair
Curvature, reflection, deviation, surface-quality analysis, and diagnostics

Create or review a practical configuration for section curves, silhouettes, feature lines, boundaries, curve fitting, and smoothing.
Build and test an exercise involving planes, cylinders, cones, spheres, extrusions, revolutions, and analytic primitives and surface fitting, patch layout, swept, through-curve, bounded, fill, and studio surfaces.
Use diagnostics or evidence to validate curvature, reflection, deviation, surface-quality analysis, and diagnostics.

Explain section curves, silhouettes, feature lines, boundaries, curve fitting, and smoothing.
Apply planes, cylinders, cones, spheres, extrusions, revolutions, and analytic primitives and surface fitting, patch layout, swept, through-curve, bounded, fill, and studio surfaces.
Validate and troubleshoot curvature, reflection, deviation, surface-quality analysis, and diagnostics.
