Hey, I have what may be a very simple question but I have just started using Mathematica and can not figure it out. I have a text file with lines of x y z values seperated by tabs, ie 223.3 233.5 2894.0 How do I get a 3d graph of the points? I would appreciate any help or a location in the Stephen Wolfram book that explains this. I have tried various functions ListPlot3D, Graphics3D but they either don't work or give me a surface that I know does not match the data. I can read the data from the file correctly. At least I think I have it in a proper format. I use pointlist=ReadList["weights.txt",{Number,Number,Number}]; Which give me a list that looks like this {{-20., -20., 68272.796875}, {-19., -20., 67817.}, {-18., -20., 67363.203125}, {-17., -20., 66911.398438}, {-16., -20., 66461.601563}, {-15., -20., 66013.796875}, thanks, Stephen Nichols
