The Set Widths of Columns, Rows, and Layers dialog box is used for specifying the exact widths of columns, rows, and layers. To display the dialog box, the user selects Grid|Set Width... or clicks the Set width button 
. Next the user clicks and drags with the mouse to select one or more columns, rows, or layers on the top, front, or side view of the model. When the mouse is released, the dialog box will appear. The average width of the elements will be displayed. The user should decide whether to edit the columns, rows, or layers and check the corresponding checkboxes. The user may then edit the range of columns, rows, or layers to be edited and set the desired width. Clicking the OK button will cause the element size of the selected columns, rows, and layers to be changed.
This method can not be used with Footprint grids because the cell spacing is required to be uniform.
