Step 7 two face :

Easier one! You had done only the left side of the first, but how about the other side?

So what we’re going to do is to “mirror” it or in 3dsmax it going to be, symmetry.

1.   Be sure to check your paper so when you click move button, the X should be zero! X=0 like you’re doing it in Step 4

2.   Now go to the “modifier” List and Take symmetry~

3.   Under symmetry parameters, Tick “x” and “flip”

4.   Result:

Feel free to check the problem and fix it by edit the vertex. Move it with your desirable needs.
