parts. The dialog box is shown by first selecting Grid|Subdivide
Grid Elements or pressing the Subdivide grid elements
button . Then the user clicks and
drags on the grid with the mouse to select a range of elements.
The elements over which the mouse moved with the mouse button depressed
will be selected and shown in a gray color. When the mouse button
is released, the Subdivide Rows, Columns, and Layers
dialog box appears. In the dialog box, the rows columns and
layers selected by the user are displayed. If desired, the user can
edit the range of columns, rows and layers displayed. The user
specifies how many columns, rows and layers each selected column, row,
and layer should be divided into and clicks the OK button to subdivide
them. After specifying how the elements are to be subdivided, the
user clicks on the OK button to subdivide the elements. Each
selected column, row, or layer will be split into the specified number
of parts. The parts making up each former element will have a
uniform width and the total width of the parts will be equal to the
total width of the selected columns, rows, or layers before they were
subdivided.
