Hi out there,
I have a problem in reading and plotting datas
discribed by {x,y,z}. e.g. there ist a list of datas x, y, z on a disk a:\

0,25.05, ...

now I`d like to read these datas in a list, called e.g.
Liste={{x,y,z),{x,y,z},...}; finally I`d like to draw a 3DPlot.
My problem is: I read these datas like this;

In[1]:= Asti="A:\\Zdaten.txt"
OpenRead[Asti] In[2]:=Do[xyz=ToExpression[Read[Asti,Word]];
Out[2]:={-30.,30.,0}            {-25.,30.,0}            and so on ...
This no list or table I can work with - can you possibly tell me how I can
get a
list or a table that looks like ...
Liste ={{-30,30,0},{-25,30,0},{x,y,z},...} Is there any command that makes a
3DPlot with this kind of data {x,y,z} - or is there an other way to plot
it 3-dimensional? - I have problems in using the command "ListPlot3D".
My "dream" is to get a 3-dimensional SurfacePlot that shows me the surface -
not only the points.

Hope you can help me,
