Why use Flow ?
Array / Curve is not sufficient ?



PS Your curve is not clean there is angle inside!
Control points are not well aligned...so any operations will be mismatched...

Hi Pilou

This is how I have it done, but I thought that instead of 450 (the base ring is just the outline) rings, putting it all together would have very little weight in memory.

How do you know how much memory it consumes?

Thanks again for your help

I don't know but the Flow was for me too long...i don't see the result in reasonable time for my old computer ...the Array curve is instant! :)
