This study is motivated by recent observations of velocity--coherent substructures (\"fibres\") in star-forming filaments. We find such \"fibres\" ubiquitously in our simulated filament. We found that a fibre in one projection is not necessarily a fibre in another projection, and thus, caution should be taken into account when considering them as real objects.
