Thank you Stefan i have forgotten how to use a SW I have written myself, for several year ago.
I was made for the surfguy's, the wanted to design there own fins for there boards
Funny ide, the supplier know how to do it.
They just need to make a outline sketch at "grid" paper. and set the dimensions.
Then input those to a little SW I have made.
The output is the TXT files you have seen. The profiles is from Airfoil arkive. I then make a STL of the generated part, the surf guys can have and fiddle around with at there 3D printers.
Thank you for the help.
