I'm looking for better capability to design agricultural buildings- especially dairy-with symbols for (e.g.) free stalls, waterers, curtain sided walls, milking parlors and related equipment, robotic milkers, etc. I've been running Chief 9.5 Full for about 8 years with residential projects, but now I'm more involved in large Dairy projects. (I'm willing to upgrade to latest version if necessary). Anyone got any suggestions?
