Will this parameter name change break existing scripts?

[adam-urbanczyk]

It could, but every time I used this method I was confused. And AFAIR I implemented it...

[lorenzncode]

Is this intended to be order dependent?

print(f.siblings(simple_box, "Edge", (1, 2)).size()) # 5
print(f.siblings(simple_box, "Edge", (2, 1)).size()) # 1 

Siblings bug: Visualize with fig. The level 3 faces are missing (blue).:

from cadquery.func import box, fuse
from cadquery.fig import Figure

fig = Figure()
fig.clear()

solid1 = fuse(
    box(1, 1, 1),
    box(1, 1, 1).moved(x=1),
    box(1, 1, 1).moved(x=2),
    box(1, 1, 1).moved(x=3),
)

seed = solid1.face("<X")

level_1 = seed.siblings(solid1, "Vertex", 1)
level_2 = seed.siblings(solid1, "Vertex", 2)
level_3 = seed.siblings(solid1, "Vertex", 3)
actual_123 = seed.siblings(solid1, "Vertex", (1, 2, 3))

fig.show(
    seed,
    name="seed",
    color="Black",
    alpha=1.0,
)

fig.show(
    solid1,
    name="solid1",
    color="LightGray",
    alpha=0.2,
)

fig.show(
    level_1,
    name="level_1",
    color="Red",
    alpha=0.8,
)

fig.show(
    level_2,
    name="level_2",
    color="Green",
    alpha=0.8,
)

fig.show(
    level_3,
    name="level_3",
    color="Blue",
    alpha=0.8,
)

fig.show(
    actual_123.moved(z=1),
    name="actual_123",
    color="Orange",
    alpha=0.8,
)

fig.iso()
fig.fit()

Thanks, will investigate.
