Description

It looks like this example was broken in the transition to PythonOCC. It fails in both CQ-editor and the jupyter_cadquery extension. Here's a jupyter_lab stack trace from this issue: https://github.com/bernhard-42/jupyter-cadquery/pull/8

IndexError                                Traceback (most recent call last)

Contributor guide

Research direction
Investigate why the workplane returns an empty set of faces. Verify that the extruded shape has the expected faces before the failing line.
