Allows you to lighten and darken the intensity of the SmartSketch grid. Grids are the net-like lines that appear on the Drawing sheet. As with the lines on graph paper, these horizontal and vertical grids allow you to plot SmartSketch elements with a high degree of precision. The grid display can be toggled on and off by clicking View > Grid Display in SmartSketch.
You can use Tools > Customize to place the Grid Brightness button on a toolbar.
