I want to align the blend to the spine, and have them perpendicular to the stroke, however they are seemingly randomly rotating. How do i fix this? I have tried everything in the blend options menu.
You can use an Artbrush to have that effect.
You can try if you can use the transform effect to rectify that. But you will probably always have to adjust it when you alter the path.
Alternatively try a scatter brush.
I’m not sure how you created your blend and got those random rotations.
Here I created a horizonal Blend.
Then used Object>Blend>Replace spine.
Is this what you want?
A Pattern Brush works well also.
