No blog post yet, but GitHub has the release code.

I'm trying to do something similar to this old tutorial (https://www.halfgaar.net/modelling-a-jet-engine), but the Prelude to modelling bit does something called dupliverts, which appears to be no longer part of Blender 4.3.

I tried an array (and applied it) but that gives me the blades as one object. How do I do this with the blades being separate objects?

Bicycles and kick scooters will be banned from footpaths that are next to cycling lanes from the fourth quarter of this year. They must stick to the cycling lane instead. Only personal mobility aids like motorised scooters will be allowed on these pedestrian-only paths. These will have a speed limit of 6 km/h by the end of next year. The Land Transport Authority says this is to keep paths safer for all, especially seniors and young children.

This is a big project on a small island
