The ability of PC-DMIS to "box-select" feature identifications now allows a union of sheet metal features between two selected groups. This functionality makes the selection of multiple three-dimensional objects much easier. Additionally, if any CAD objects are box-selected and then a CAD object is chosen without box selection, those objects that were box-selected become permanent selections in addition to the single selection.
For specific information on how to use this capability, see "Box-Selecting to Create Multiple Auto Features" in the "Creating Auto Features" chapter.
