.. _auto_curves_cartesian_to_cylindrical:

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

Converts one or more curves from Cartesian coordinates (x, y, z) to cylindrical coordinates (r, θ, z). Use this worker whenever downstream processing requires radial/angular representations of curve data, such as rotational or axisymmetric analyses.

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

Classification: **process**.

Tagged: ``cartesian``, ``coordinate_transform``, ``curve``, ``cylindrical``, ``geometry``.

     - One or more input curves in Cartesian (x, y, z) coordinate form; accepts multiple curve objects. Leave unconnected only if curves are supplied via an upstream default — otherwise required.
