Open Lattice Brickwork

[trbrock]

I am designing an elevated beach house that sits on pilings faced with brick arches that will have a single thickness open lattice brickwork inset in the arch to allow for water to flow through if we have a big storm.
Does anyone know how to generate this 3D pattern without using a separate CAD program and then importing the pattern. I tried using 3 3/8x4x8 inch soffits with a 12" repeat, which gives a 4" space between bricks. Then I raised the next soffit 3 3/8 inch off the floor with the same repeat and then moved it over the first row offset so the there was a space below each solid brick. Then I raised the next row 6 3/4 and repeated the process until the wall was as high as I needed. This looks great but the process is very labor intensive and Chief crashes when the structure gets too large. It would be nice if Chief had a 3D Configurable Pattern Generator. I can think of a large number of uses and it would be a tremendous time saver.
