11. Scale up vertexes selection on the Y-axis to move them further apart so the ball becomes round again.

12. The ball doesn’t need to be 100% smooth yet, it may have a small bump or indent as those will disappear later on when we add more details. But make sure the ball is at least round, and not egg-shaped for example. For the best results, you can add a second sphere, of the same size, but with 32 segments, on the same location, as a reference ball. You can skip this step and the following two steps if you can do this “manually”. Create the second sphere on the Left viewport starting from the center of the first sphere and you will see something like this:

13. Press F3 to turn on shading in the viewport and your balls should look similar to the following image (the green ball is the second sphere we created as a reference):

If you only see one ball, increase or decrease the size of the second sphere until they partly overlap. As you can see in the image above, we need to move down the top of the ball a bit to make it rounder, which we will do in the next step. Use F3 to turn on and off shading while performing these steps so you can see the results in a wireframe and shaded version.

14. The goal is to make sure the balls overlap an almost equal amount on the top half of the ball. Select Sphere01 again, and press F3 to switch back to wireframe view. Go to vertex mode, select the 37 vertexes as shown in the image below, and move them down a bit.

15. Select the 21 vertexes as shown in the image below, and move them down a bit, and then scale them up a bit. Toggle F3 to check the results. You should end up with something similar to the following:

16. When you are happy with the roundness of the top half of the ball select all the polygons of the bottom half of the ball and delete them. Also hide or delete the reference sphere.

17. Select all the other polygons. Press the Angle Snap Toggle button. Rotate the polygon selection 180 degrees over the X or the Z-axis while holding the Shift button. When you release the mouse button choose Element on the Clone Part of Mesh dialog box and press OK.

18. Move down polygons to below the top half of the ball. Rotate (the bottom half) 90 degrees over Y-axis (horizontal).

19. Select the bottom row of vertexes of the top half and the top row of vertexes of the bottom half (see selection rectangle in image below), press the square button next to Weld. Increase the Weld Threshold as necessary until you have a total of 122 vertexes in the model. You should have 32 vertexes selected before welding, and 16 after welding.

20. Set the TurboSmooth or MeshSmooth modifier’s Iteration setting to 1. Right-click the modifier and select Collapse All.
