Scale it up 160 times.

Something like this?

Yest that is correct, But how? I can scale it, I don´t know the current size to begin with as I am not able to add dimensions as you have. 

 

What steps did you take?

 

Thank you,

it looks great. Can you also describe me how you created the airfoil and l can design the rest of the foils? I just need the 2D case.
thank you so much. I appreciate your help.

The text file must be X,Y format, instead of having 5 spaces between your X and Y you replace them with a comma.

 

1.00000,0.00000
0.95022,0.00789
0.90043,0.01750
0.85057,0.02755
0.80065,0.03739
0.75066,0.04661

 

Then hightlight the coords, copy then in autocad type in: SPLINE

when it prompt for points, click in the command space and PASTE , hit enter several times to accept then when it stops, ZOOM all,

that's all to it.

Thank you so much. I appreciate your help. Now, I want to add more points like 200 points and export the point coordinates to a text file. Can I do that in autocad?

Thanks
