need help to create the geometry of a J-shaped airfoil in two dimension
 

hi
In ansys design modeler:
By using the curve from points command, I create two curves and then i close the open ends with the line from points command. So far, everything is correct(image 1), but when I create suface from the edges ,the curves breaks at several points(image 2).(I import the sketch from solid works too but I faced the same problem too).anyone could help me please?
