I am trying to extract all "long" lines from this alembic mesh
My first assumption was to somehow use the fact that they go along the U coordinate.
I used a simple expression to store the original position and convert this mesh to a "UV grid"
v@PStore = @P; @P = @uv;
This made things look easier but I still couldn't figure out how to keep only the horizontal lines.
So I wrote a script that would delete the vertical ones based on their length since I was lucky that all of them had a larger @restlength.
In the end after restoring the @P to the one I stored earlier I achieved the result but I am sure that there is a more elegant way to select only the "U" prims.
I would appreciate any pointers on a more logical way to achieve that result.
Thank you
