The calculator takes an array of two dimensional coordinates as input. The array should contain the coordinates in order, one point per line. Each line contains the (x) coordinate, some whitespace and/or the comma character, and then the (y) coordinate. Spreadsheet and other software can be used to generate this set as two columns (x,y) of numeric values. Depending on the tool you are using to generate the point coordinates, you can either generate a .csv (comma separated values) file of the points, or simply select and copy that portion of the spreadsheet onto the clipboard.
Once the array of coordinates is on the clipboard, you can paste it into the input text box of the calculator. If all looks good, select the output file format you want (.dxf or .svg) and click on the Calculate button.
If the Status box says "complete" then the conversion was successful and you can save the file to disk by pressing the SAVE TO DISK button in the lower right corner (sometimes you have to hover the cursor there to make the button appear). Note that the save function uses flash, which must be installed and enabled in your browser. If flash is not installed and enabled the SAVE TO DISK button will not appear in the bottom right corner of the calculator.
