Toroidal Helix: A Complex CATIA Exercise
Recreating a toroidal helix from a practice drawing in CATIA using a simple construction method and a fully parametric Curve from Equation method.
Browse contents
This is a complex CATIA exercise based on a reference drawing. The goal is to recreate a toroidal helix using two different approaches and compare the result.
The reference drawing
This drawing comes from Too Tall Toby's User Submitted CAD Challenges. It was created and submitted by Koska.
Method 1: Direct Construction
The simple method uses standard CATIA construction tools to recreate the shape directly from the drawing.
Method 2: Fully Parametric Curve from Equation
The complex method uses CATIA's Curve from Equation feature to define the toroidal helix fully parametrically.
