I recently saw a post featuring a Lamella Zollinger rhomboid pattern reciprocal roof structure and I’m intrigued..  I’m looking for a calculator, or a long hand method to develop the two patterns required to build one.  I tried messing around with this software, but it’s french. https://1drv.ms/u/s!AsPME1vgV0IRgfEVlyDF57O2Pw_dzA?e=dw0xCt  

 There’s more pro’s than con’s with these structures imo, and does anyone have any suggestions on how to figure out the two structural shapes, short of hiring a engineer proficient with Rhinoceros CAD 3D?

  Yes, I tried to contact rural sw Alabama auburn studio because their Hale county animal shelter is the shape and diameter I want.

Thanks
