*CONVERT CARTESIAN TO CYLINDRICAL*
==================================

Converts a curve defined in Cartesian coordinates (x, y, z) to cylindrical coordinates (r, θ, z). Use this worker whenever downstream processing or visualization requires a cylindrical reference frame, such as axisymmetric structures, rotating components, or radial cross-section analysis.

When to use
-----------

Classification: **process**.
