Hi, i need to replicate the ring above. Head is fine - did that with sub d. The body is about 176.27mm long and i planned on using flow and either creating subd scales or just boolean differencing a cut along the body to replicate an engraved look.

but each way ends up with my program running very slowly not responding for a number of minutes at a time

does anyone have any ideas of how else i can achieve this?

this is a flowAlongSrf (preserve Structure = true) with a subd with 4800 Faces.

took around 10 or 15 seconds to flow…

maybe provide some .3dm file so the forum can see what s wrong / how to precisely help.

kind regards - tom

the file is too big.

the shape is not a perfect spiral so im not sure how to construct a surface from it

this is what happens when i use flow. it twists at the ends and doesnt hold a cylindrical shape

flow (that uses a curve) is the wrong command here.
you will need flowAlongSrf


please post at least this curve as 3dm so the forum can play around with it.
SaveSmall might reduce the file size if you have huge render- / analyse Mesh Data.

its too big to attach the full file. i have flow along srf working but it is warping the scales like so:

is this closer to what you re after ? … uff … a few tricks and a custom script … but a nice “how to do this”-riddle…
