how to fix airfoil geometry in SolidWorks?

Hello everybody,

I am new to SolidWorks and I would like to model a wind turbine in SW.

I have imported airfoil coordinates by using ''curve through xyz point'', now I plan to move the airfoil and loft it through a 3D curve.

My first question is that might airfoil geometry change by moving or lofting?

If yeswhat should I do to fix the airfiol geometry? 

Thank you in advance,

bahar.
