There are several enhancements in Costing for SOLIDWORKS 2017. First, the bounding Box Preview now allows you to view either the first or last sheet when multiple sheets are required. This allows users to make modifications or alter the lot size to maximize sheet usage. In SOLIDWORKS 2016, we introduced rules based costing for machined parts, now in 2017 rules can now applied for sheet metal parts as well to get more accurate cost information.
