Thanks for your response.. I have created two surfaces and able to get multiple sections, one of which is shown in attachment. Also able to generate a Total Volume table as in Table1. But I need to generate a Table either in the format as in Table1 for only 770-690 elevation range or a table in the format as in Table 2. If you are done, you could be a great help to me... sorry for replying thrice, im unable to attach file.. this I was done.
