Meshing a SW part

Hi, I am attempting to do an aero-elastic analysis of a wing using Femap. I start by pulling the wing profiles into Solidworks. Then I convert entities to change the dat file of coordinates into a line on a plane. At this stage I put in a vertical line to indicate where I want the main spar to be and cut off the rear portion of the airfoil, this will be the rear spar, (1). I then pull this sldprt into Femap by Import Geometry, (2). When this is done I try to mesh it but cannot. Upon examination I find that some lines do not end exactly on the point chosen, (3). How do I go about 'cleaning up' my model and putting a surface around it then meshing this surface?
Best regards
