After selecting the
Create Grid button from the Digitizer (Advanced) toolbar or the digitizer popup menu
option, the user can proceed to select the anchor point (top left corner)
of the grid by left clicking at the desired location. Cancel creation
of the point(s) at any time by pressing the Escape key or right clicking.
After selecting the anchor point for the grid, the Grid Setup dialog (pictured below) appears and allows the user to setup the size, count, naming, and orientation of the grid cells.
This section provides a number of options to derive grid cell sizes and counts.
Select the Anchor Grid Top Left to Clicked Position option and specify the Rows, Columns, and Grid Cell width and height to derive a grid based on size.

Calculate Grid Cell Sizes to Fill Rectangle - Select this options and then choose a rectangle area feature to calculate grid cell sizes or cell counts to fill the selected rectangle.
Grid Naming - Select the naming convention to be used in naming the Grid cells. By default Rows and then Columns will be named, with Rows starting with 'A' and Columns with '1'.
- With this option, a number starting at 1 for the top-left tile will be appended to the selected export filename. The number will increase across each row.
- With this option, separate indicators will be appended to the selected export filename for the row and column. If letters are selected, the letters A-Z will be used. If more than 27 letters are needed, multiple letters will be used (e.g. AA, AB, etc.). If numbers are used, the number values will be pre-pended with zeroes in order to make the numeric values have the same number of characters for every output tile. If the Reverse checkbox is marked, the order or the numbers or letters used will be reversed (e.g. if there are 4 rows and numeric naming is selected, the rows will be named 4, 3, 2, 1 instead of 1, 2, 3, 4). The user also has the option of specifying the letter/number to start naming at as well as the option to specify a prefix for each column and row number for each tile and the option to specify by what value numeric names should change by (step) for each successive row or column.
If the Reverse Naming option is checked, the column name will come before the row name in the export filename, otherwise the row name will be before the column name.
If the Prepend 0 to Numbers to Make Same Length option is checked, the longest number will be found for both the column and row names and all other column/row names will have 0's prepended to make them all the same length. The same applies to column/row names using letters if the Prepend A to Letters to Make Same Length option is checked.
The Separate Rows and Columns with Underscore option causes an underscore to be used to separate row and column values in the output filenames. If not checked then no separator character will be used.
Allows user to create grid line and area features. There are also options to create points at grid line intersections, endpoints and cell centers.
