DIY builders waste materials and time calculating optimal CMU block layouts to minimize cutting and small pieces

DIY homeowners and contractors struggle to plan CMU (concrete masonry unit) block wall layouts that avoid awkward small blocks at the end of rows, which wastes expensive materials, creates structural weak points, and requires time-consuming recalculation. Existing solutions require manual trial-and-error or expensive professional consultation, leaving most builders guessing and making costly mistakes during construction.
