Then you can select all the edges and weld them together, as shown
in Figure 3-52.
Now you have a nice top that you’ve made manually.
Bump
Modeling circular edge loops by hand is the safest way to carve or
bump polygonal objects and reduce mesh errors. When you cut an
eight-sided edge, you have the opportunity to plan how the mesh
will behave because you can cut, remove edges, and merge vertices
as much as you need.
First we cut an “X” in the top of the box, then cut a “+” to give
us eight intersecting lines. Then we draw a poly-circle in the mid-
dle, as shown in Figure 3-53.
Select the polygons inside the circle and extrude it a little bit, then
extrude again. This will generate tension in the base. Extrude
again, a little higher.

After the extrusion, scale down the top polygons. You may want to
cut near the top of the extruded object to improve the tension at the
top.
Notice the differences between the two images in Figure 3-56. The
one on the left represents the extruded shape, and the one on the
right is the same shape with one of the base edges removed.
