To properly utilize the weldments features for Solidworks an understanding of the cut list structure is required. Once the Weldment feature is added to a part a few changes are made, including a change from "Solid bodies" to "Cut-List" in the feature manager. This cut list can be linked to drawings and passed to a machinist to facilitate the cutting of proper profile lengths. Consolidating items for the cut list is important, a weldment that requires 40 structural components may only contain 3 or four distinct parts. Grouping of identical items and specifications is done through a folder structure as a part of the "Cut-List" feature.
Once the "Automatic" feature is click the Cut-List will be organized into folders. A folder is created for each unique part, with a quantity noted in parenthesis. My simple example was a rectangular box with a single cross member which created 4 folders, one each for the length/width/height members and another for the cross member.
All items in the folder are named based upon the last feature to modify that body (Structrual Member 1). The order within that feature  denotes the first item created in the feature,  the second and so on. Items can be manually added to folders by dragging and dropping them. For most applications though the drag/drop feature should be avoided as the software does a fairly nice job of grouping items together correctly.
