I'm wanting to make a bundle of fibers to along an organic shape (so not a cylinder). I have the 3D model of the shape (an approximation of a muscle), and I want the fibers aligned to the longest axis. Here is a picture of the model:
So far I've done the trick of selecting all the vertices, doing the 'Checker Deselect' function, separating out the selected vertices, turning those vertices into a curve, and then going to the Object Data Properties for the curve and changing the bevel size from 0 to a nonzero number.
The result is cool but I need the fibers to only run the longest length of the muscle. Is there a function that I'm missing that can get rid of the crossbars?
