My program create text .txt files that is used in SolidWorks and Rhino3D
It is 7 files, one for each blade station, that have X, Y and Z
co-ordinates, with the proper angle and placed correctly in relation to
the
plan form that is chosen (6 of them)

In SolidWorks it is just to insert "curve through free points" one by one
txt file, then loft from station 1 to 7 and the blade is don. It is don
faster then it take to write this, it's just a matter of clicking with the
mouse. no writing of co-ordinates.

So the .txt files are a text based set of points that can be imported like
an .igs file? Then add some "skin" to them and you're ready to go?
