Select the edges that you want to combine.
You can use a combination of drag-select, ShiftClick, CtrlClick, and the angle method to select more than one edge to combine. For more information, see Selecting objects within the current viewport.
Abaqus/CAE combines the selected edges. You can use the Model Tree or the Restore Entities tool to restore the selected edges. For more information on restoring individual entities, see Restoring entities that were replaced by virtual topology.
