MasCalc is an inexpensive, trade-specific alternative to CAD that assists designers with often overlooked masonry details. The software saves architects, contractors, builders, and manufacturers the time and expense of manually calculating the dimensions for special masonry shapes, such as arches, radial brick, non-90-degree angle corner brick, and keystones. By entering the size of the masonry unit and a few additional measurements, the program calculates all the dimensions needed to produce a professional product.
