I have a woven mesh modeled and am trying to create and extrusion of another part/feature that "flows" around the mesh.  I have no idea if this is possible.  I have tried everything I can think of with extruding in the assembly to extruding it as a part and deleting the mesh. No matter what It is always solid right through the mesh.

I woould like to fill the the area without filling the existing mesh volume so I can acuratly calculate the amount and weight of material.

Any suggestions?
