Sorry, i am not sure if i really understood what you want... but here is a solution for thaht what i understood.
- Get a empty-PolyMesh
- ICETree
- Grab the "Create Extrusion Along Strands"-Compound
- Set the BaseShape Nb Subdivisions to 2
- Go into the Compound to: Create Extrusion Along Strands / Apply Extrusion / Build Quads Description / Build Last Quads Description
- Set the Integer at the Left Subtract-Node to 2
Here is my Result and the Way to do this.
Becouse i dont got a XSI2013 i cant test this with Tim's FeatherCompound
