hi there could someone point me a way to generate an output data file in the following format:

x-coordinate y-coordinate x-velocity y-velocity 1.0 2.0 4.5 6.7 1.2 2.0 4.6 6.8

p/s: export to ASCII format does not produce the above format. thanks in advance. yf

You should use a UDF. There are some macros yuo can use to get the informations you neeed. You can write a program using the C language and export what you need in a file. Hope it helps. Luca

hi thanks!!
