ANSYS DESIGN MODELER - NACA 4412 - Import Points - Part 1B/4

Hi, I want to use the fluent to analyse a 2d airfoil, can I follow this tutorial to the de mesh? If so, what changes I need to do?

My airfoil model has a chord and thickness of 15cm , after using the scale tool i had a problem adjusting the enclosure dimensions ,,
