  1. How would you go about importing a .dxf AutoCad2004 file into Surfer 8.0? My primary reason for doing this is to make groundwater elevation contours in Surfer off an Auto Cad Drawing. Also, is it necessary to digitize all monitoring wells, once my map is imported into Surfer, so that I could begin assigning data to each well to make contours? Thanks in advance to anyone and everyone who can help with this.
  2. Does anybody know how to make, or go about starting to make, a cross section in Surfer 8.0?
  3. Does anybody know how to convert a surfer file to a .pdf file so that I could save a surfer file to a .pdf file and email it to someone? Keep in mind that I don't want who ever receives my email to be able to protect it, and I hope by doing this it will be protected. Thanks!
  4. Surfer 8.0 Cross-Sections

    Hi TomB, Thanks for the help altough I am stuck with getting started. How would I go about creating an ASCII file in a BLN format? Thank you. SafeMan - One way to make a cross-section in Surfer 8 is to grid the data to a GRD file, create an ASCII file in BLN format to define the trace of the cross-secition, and choose Grid | Slice to output an ASCII DAT file with the profile information. The DAT file has a row for each point where the trace of the cross-section crosses a grid line in the GRD file. There are five columns: column A: X coordinate. column B: Y coordinate. column C: Z coordinates. column D: cumulative distance in XY units. column E: profile number, i.e. 1, 2, 3, ... for multiple profiles. - If you have a 2D graphing package to display the cross-section, plot column D along the X axis of the graph and column C along the Y axis. - Surfer 8 requires some file manipulation to display the cross-section within Surfer. Open output DAT file in the Surfer worksheet with File | Open, move column D to column A, column C to column B, and delete column E. Press the END key to navigate to the end of the worksheet, and note the row number of the last row with data to get the number of vertices in the cross-section. Add a blank row at row 1, enter the number of vertices in the section in cell A1, and save the changes to a file with a BLN extension, e.g. cross-section1.bln. Close the worksheet. In the Surfer plot window, load the BLN file with the Map | Base Map menu command. By default, Surfer plots base maps with the same X and Y scale. Many cross-sections require different scales in the X and Y direction. To change the scale, double-click on the base map in the plot window or in the Object Manager list on the left side of the Surfer window to display the Properties dialog, click on the Scale tab, remove the check mark from the Proportional XY Scaling option in the lower left section of the Properties dialog, and enter the desired Length values for the X and Y scale. For example, I like to use an X Length of 8 inches and a Y length of 2 inches. Tom B Tom Bresnahan RockWare, Inc. [email protected]
  5. Importing an Auto Cad file into Surfer

    Hi Tom B, Thanks for the help. I made sure my Auto Cad document only had XY data and not XYZ data, and it did. When I clicked on "Map" then "Base Map..." and selected the .dxf file I wanted to import, after selecting this file it plotted on my map as a very small image (see attachment). How would I adjust the image I want to import into AutoCad so that it would fill more of the plot document? It is so small that I barely see it (see the bottom left of the base map near 0 on the x axis). Is this problem becasue of something of how I saved it from AutoCad? Does it have to do with the image size or how I capture/save it in Auto Cad? Thanks for all your help, as I'm quite the novice in both programs, it turns out! -SafeMan
