Merge Grids?

Hello, I am new to Grasshopper and am trying to create an algorithm in which I have two rectangular grids are interwoven, so every other row is shifted 90 degrees. Is it possible to create these two grids in the same formula? Or do I need one formula for rows 1, 3,5, 7 etc, and another for rows 2, 4, 6, 8, 10 etc? Then, I am trying to popular the grid with boxes whose orientation follows the grid direction. I am attaching the rhino file and grasshopper file. Thanks!

WARNING!!! Opened the GH file and the Rhino/GH app is frozen - very LONG TIME now...

Later - still waiting. Always a good idea to work at low resolution until the algorithm is perfected before cranking it up to hi-res and paying a heavy performance price.

Finally! 60K+ points in each of two "threads", culled to ~30K each. OUCH!!!!

Hi Joseph, Thanks for the feedback. I am definitely having issues with the slow speed. Do you have any suggestions of how to reduce the file size? Here is an example that works much better when instead of individual components I use a group of 4' x 4'. The issue is that then the CULL only effects the entire group, not each individual block of 4' x 1' x 7". Sorry I am such a beginner, but really really appreciate the help!

Frankly, I'm reluctant to spend more time on this without a clearer picture of what you are trying to do. Sorry.

OK, before anything else, let me suggest this:

Disable solver before opening this file!
Change 'Ex' and 'Ey' sliders for both 'RecGrid' components to five. This reduces "resolution" to about ~2K points in each.
Re-enable solver.

There are two 'Series' components with 'Count' sliders set at 56 but reducing them appears to change the results in critical ways so I left them alone.

Still, I can't make any sense of this, sorry. Can you provide a picture of your objectives?
