CadQuery: Jak opravit cq.Location() error: TypeError: Expected three floats, OCC gp_, or 3-tuple

Problém

Pokoušíte se konstruovat cq.Location objekt pomocí kódu jako

cadquery_fix.py

cq.Location(1, 2, 3)

cq.Location(1, 2, 3)

nicméně když ho spustíte, vidíte následující chybovou zprávu:

   1012     )
   1013     T.SetTranslationPart(Vector(t).wrapped)

Řešení

Nepředávejte tři samostatné parametry cq.Location() - předejte tuple se třemi čísly přidáním další sady závorek:

cadquery_fix.py

cq.Location((1, 2, 3))

cq.Location((1, 2, 3))
