Hi Emily,

So here's the sketch I promised.  lamella_logic-Model.pdf

Essentially what you need to accomplish is to:

1. Remap the UV of the surface you started with in order to overlay a grid that will be the basis of creating lamella members.  In the sketch I'll use the 8 m side as U and 6 m as V.  The surface is divided into a grid comprised of 1 m² squares.  This step is not strictly needed but I use it to calculate the spacing in each direction for trimming.

2. Remap the UV of the surface again to generate the grid for lamella members in each direction.  This grid subdivisions will be twice the size of the basic grid from step 1.  Before remapping the grid I'm pretty sure I trimmed off the ends of the surface in the U direction by 1/2 the grid division distance (1 m off each end in the sketch).  Repeat this for V, but in the other direction.

3. Extract the diagonals in each of the grids from step 2.  Connect points 0 & 2 to form on diagonal, and 1 & 3 for the other diagonal.  This will create lines for generating the lamella ribs.  You'll have to dig around my definition to see how that's done...it will be very difficult for me to type that out.

4. Others probably have cleaner methods of producing the same effect.  I know I certainly didn't put much effort into cleaning up the definition.
