Circular blend Illustrator
Using Illustrator, I am trying to blend objects in a circular fashion but can't seem to find a satisfying solution. I have considered using the rotate tool, copying the rotated object around a central axis and then holding down command-d to complete the "blend" but find this method inefficient. I have also considered replacing the spline of a blend with a circle, but it seems that no matter what, the blend can never go past 3/4 of a circle (see GIF below). Am I missing something?
This happens when you replace the spine of a blend with a closed path. The blend can't use the same point as a beginning and end point so you get a section of your path not being used.
To fix the issue just use the Scissors Tool (C) on the path to create an open path.
