Why 2D nozzle planar curve not smooth?

I make 2D planar surface using solidworks.

The curve is so smooth in solidworks.

But not smooth in ANSYS Fluent design modeler.

Why occurs that???

How I make smooth curve????
and When I make mesh using the not smooth curve, Fluent not working???

What file format do you use when importing to design modeler? I usually doing it by exporting the geometry to a .STP or .STEP, so far works fine for me. One time tried by using .sat file my friend gave me, the complex geometry is a mess.
I wound recommend to use either design modeler or Spaceclaim, less error will occur if I do it this way.

It could also be just graphical?
What happens after you mesh it? is the curve then smooth?
