cutThruAll failure

[adam-urbanczyk]

The following code fails:

import cadquery as cq

sphere_r = 10.

result = (cq.Workplane("XY").sphere(sphere_r)
            .workplane(centerOption="ProjectedOrigin").circle(sphere_r / 2.).cutThruAll()
            .workplane(centerOption="ProjectedOrigin").transformed(rotate=(90, 0, 0))
            .circle(sphere_r / 2.).cutThruAll()
            .workplane(centerOption="ProjectedOrigin").transformed(rotate=(0, 90, 0))
            .circle(sphere_r / 2.).cutThruAll()
            .workplane(centerOption="ProjectedOrigin").circle(sphere_r / 2.).extrude(sphere_r + 2, both=True))

perturbaing one of the angles makes it work

import cadquery as cq

sphere_r = 10.

result = (cq.Workplane("XY").sphere(sphere_r)
            .workplane(centerOption="ProjectedOrigin").circle(sphere_r / 2.).cutThruAll()
            .workplane(centerOption="ProjectedOrigin").transformed(rotate=(90, 0, 0))
            .circle(sphere_r / 2.).cutThruAll()
            .workplane(centerOption="ProjectedOrigin").transformed(rotate=(0, 89.9, 0))
            .circle(sphere_r / 2.).cutThruAll()
            .workplane(centerOption="ProjectedOrigin").circle(sphere_r / 2.).extrude(sphere_r + 2, both=True))

show_object(result)

None of this works now. Using an old release (CQ-editor compiled for Windows) the second code works as expected.

Error code

Traceback (most recent call last):
  File "/testing/src/cutThruAll/C2.py", line 7, in <module>
    result = (cq.Workplane("XY").sphere(sphere_r)

    faceRef = sel2.filter(faces)[0]
  File "/cadquery/cadquery/selectors.py", line 103, in filter
    return [min(objectList, key=dist)]
ValueError: min() arg is an empty sequence

Tested with (almost) the latest release using Docker. Find the docker image here.

Thanks, will try to fix this ASAP.
