Build high-quality, continuous curves (splines, connect curves) with proper tangency (G1) and curvature (G2) continuity.

Parametric design relies on defined parameters, constraints, and relationships to drive geometry. If you change a single dimension, the entire model updates automatically. Explicit modeling, conversely, treats geometry as static, unlinked shapes. Advanced parametric design uses formulas, design tables, and external parameters to create intelligent, self-updating systems rather than simple static parts.

The error message "Update Diagnosis: Feature formulation failed" is a common headache for CAD designers. These errors typically stem from parent-child relationship failures or topological changes. The "Dangling Reference" Problem If you change a single dimension, the entire
Develop the outer skin using Sweep , Multi-Sections Surface , or Blend features. Ensure surface continuity matches your engineering requirements: Point continuity (touching). G1: Tangent continuity (smooth transition). What is Hybrid Design
Unlike purely history-based modelers (like SOLIDWORKS or Inventor), CATIA’s mode allows you to mix solid and surface geometry freely in the same tree.
Prepare a 40–80 page fixed PDF covering the above, include 2–3 full worked examples with native files, and provide a one-page quick reference cheat sheet for daily use.
