Illustrator Import to After Effects I have an illustrator file with vector paths made up of all strokes. When imported into AE and converted to shape layers, all the strokes turn into filled shapes. I want them to stay as strokes so I can utilize Trim paths. Any Idea about this?
I've had success with 

import composition > layer size

Double click comp

Highlight all > Create > Create Shapes from vector layer

Delete the .Ai layers
