Surprisingly, this is really simple in all other CAD packages I have used. In AutoCAD, I-deas, and ProE it would hardly need automation ... but reading a text file into a program in Catia is so difficult. Well, as always, it is about knowing the process, but the process in this case is very difficult.
Hmm ... actually I need to read text files (a number of them) and insert them at specific places around my drawing. Thus things are not as easy for me.
For your part - a method that I use often. You can CUT-PASTE your data file into the comment file. Getting text out of a comment file is easy. Thus you can get the text, use string functions to get the coordinates, and finally plot them. Well, a bit more difficult, but this one wont need another software.
