I have spent all morning trying to create a surface plot from a set of survey data that I have. The data I have is in the format xi, yi, zi. It is in Excel in columns. I read some previous questions on this topic, but my plot just comes out all jumbled. Here is what I coded.
As soon as I figure out how to post images, i will post the plot...

"a" is the name of the data that I imported from Excel
aa := [seq(a[i, 1], i = 1 .. 46)];
bb := [seq(a[i, 2], i = 1 .. 46)];
cc := [seq(a[i, 3], i = 1 .. 46)];
plots[surfdata]([seq([seq([aa[i+23*j], bb[i+23*j], cc[i+23*j]], i = 1 .. 23)], j = 0 .. 1)]);
The discussion that I read to get even this far is here:
Here are the first three points from Excel:
