That night, Leo opened CATIA V5. He stared at the blank coordinate system. The GSD workbench was a ghost town of unfamiliar icons: Sweep, Loft, Split, Join, Fill, PowerCopy. He felt like a carpenter who had just been asked to perform heart surgery.
Over three weeks, Leo worked through all 50 exercises. He learned to craft a teardrop-shaped car mirror (Exercise 38), a turbine blade with variable fillets (Exercise 42), and a parametric dimple pattern using PowerCopy (Exercise 49). The final exercise, #50, was a single sentence: “Design a Y-shaped air duct with a smooth blend from one circular inlet to two rectangular outlets. No visible seams.” generative shape design catia v5 exercises pdf
The PDF did something his college textbook never did: it forced failure. Exercise 31 deliberately gave him under-constrained curves. When he tried to Fill the surface, CATIA threw an error. The PDF’s margin note read: “GSD hates gaps. Use ‘Healing’ or rebuild the curve with G1 continuity.” That single line taught him more about surface integrity than a semester of lectures.
