If I have an excavation and a point on the crest (or a bunch of crest points) and I put in a slope of 4:1 and I have a known pit bottom floor. Will Surfer be able to calculate where the slope intersects the pit floor and what the XYZ coordinates will be at the point?

I need to apologize but I am still confused. Do I digitize the polygon that I have already created in the drawing? How many points should I get? When I open the BLN in a worksheet is it the worksheet that contains the coordinates for the contour map, or do I open a new Worksheet? Once I create the BLN file and change the cell B1 from 1 to 0 and save the changes do I create a Grid file from that?

I need help trying to figure out how to keep the contours within a defined area. I can specify the maximum and minimum x and y boundaries but the shape of the area I am using is more like a trapezoid and the contour lines are going outside the area because the program things it is a square.

Hi,
Everytime I select the drawing tools in a Surfer 8 Plot the progranm quits responding. Is this because I am now using Windows 7? Do you have any other ideas as this is extemely frustrating.

I have Surfer 9 and it gives me the area of the polygon but not the surface area of the land in the survey coordinates. Example: The area of the polygon was 439.77321590909 cm2 on a drawing of 1:5000 scale. Ineed the land area in m2 or Ha or Acres

I finally figured out how to grid the data and how to use the two different grids (the upper and lower surface) to get a volume. My next question is: If the elevation is in metres then is the volume in cubic metres??

I am really new at using Surfer and I am not sure how to make a grid. Is it just a grid map as I do have all the original survey data including elevations from 2006 and the most up to date survey.
I would appreciate it if you could help me learn to make grids or point me in the direction to find out how to do it.

I need help with calculating volumes for a gravel deposit. I have an original contour surface drawn from 2006 and a new contoured surface for 2008. I need to be able to show the differences between the two on the drawing (e.g. -12m etc..) and then be able to calculate what volume of material has been moved out of the pit since 2006.
