autocad question

If you no the format of the cad file you need to create you could write a macro in excel to create the file for you.

You'll be better off asking this question on the AutoCAD NG. My approach would have been to output the points as a text file with one coordinate per line: x1 y1 x2 y2 ...... xn yn

Then a simple AutoLISP program can read this text file into AutoCAD and create points or connect these points with a polyline - whatever you want. You can make AutoLISP read a CSV file, which is one of the standard EXCEL export formats, but for a casual AutoLISP dabbler it will be faster to spend time on simplifying the point file than on writing a more complex CSV import routine.
