I am trying to model a wing in Solidworks 2010. I know everything about importing airfoil data. I take airfoil coordinates from UIUC database.
Whenever I use "Insert Curve through XYZ" to insert airfoil data, the curve that appears is not a closed profile but an open one. I tried some other airfoils and got same thing. I have gone through many tutorials and everyone gets a closed curve but I can't understand why I cannot. The below image is of NACA0013 airfoil.
I tried manually adjusting the coordinates and closing the profile but the profile gets a soemwhat distorted at the trailing edge. I have to do CFD simulation afterward so I need an accurate profile. Please help me out.
