The OrCAD PCB Editor Quickplace is an application used to ‘quickly’ scatter components around the perimeter of the design or to a room location. By default, components are placed not to overlap each other. As a result, the application may fail to place components if space is not available. A new control option in the 16.6 release,"Overlap components by," has been introduced to improve completion percentages. You can control the amount of overlap - the default value is seeded at 50%.
