Hi, any ideas how to get flow along curve to work on non planar curves? The objects never actually follow the target curve properly, it needs manual adjustment on the base curve. See attached. Thanks flow along curve question.zip (16.0 MB)

It appears the problem is the objects are not oriented as desired when flowed along the target curve. Flow does not have any knowledge of the adjacent surface. Have you tried using FlowAlongSrf? Create a target surface, UnrollSrfUV/Squish it, position the objects along the flattened surface, and th…

it is the same issue, and flow along surface it is more work. Flow along curve is not a problem if the target curve it is a planar curve. But as soon as the target curve is not planar, it does not work.

Solution: Create a surface which will be used to flow the objects and unroll that surface and the target curve. DupEdge Loft with straight edges between the duplicated edges Split with Isocurve at the end of the target curve. UnrollSrfUV the new surface and the target curve. [image] Flow the…

Thanks! I was hoping there was a solution for the flow along curve, which is a quicker method. I know array along curve has the same issues and has been fixed, perhaps FAC is next

thanks guys! I know array along curve will change , I was hoping the same was happening for flow along curve. I use flow along surface sometimes but it takes longer for more complex surfaces, have to break the surfaces, unroll, etc. Extract isocurves and flow would be quicker, if it worked :-), but …

Hi @theoutside Are there any plans to get flow along surface working better/more efficient in V9? Glad flow along curve is getting attention. I’m currently using the standard workflow David posted but I need to further unwrap my linework after its flown on a surface. I’m doing stencils on cups and…

@Trav would know better than I would what the status there is-

Davids solution is great and he beat me to it -
I’d go that way-

fwiw, array along curve is getting a MASSIVE rewrite for v9 and is going to blow more than a few minds for this type of work.
