Concrete Edge Distances (to Plate): Pressing the infinity button will mark that edge distance as infinite. Note that doing this will cause the algorithm to skip some calculations. If you do not want to skip any calculations, but still want to model a very large edge distance, set the edge distance to 99 inches. This is especially significant for PCI designs, as the program will assume that an edge will influence the design as a two-parallel-edge condition unless you set one of the edge distances to infinity.
Top edge to first row: Distance between the top edge of the plate and the centerline of the closest row.
