Make sure you get all the options and settings for the Spin right after you

make the Spin because the menu disappears after you start another

operation in Blender.

In the Spin menu, you find an option called “Use Duplicates“ that doesn't

connect the Spin's copies. It works like a rotation based Array.

4.7 Proportional editing

The transformations we apply to any polygon elements in Blender take

full effect on selected elements; they will not influence anything at their

surroundings if not selected. For instance, if you choose a couple of

vertices from a polygon with hundreds of vertices and press the S key, it

will apply a scale only to the selected vertices.

What if you also wanted to apply transformations to surrounding vertices

with a lower influence? You can do that with the Proportional Editing

tools. The option is available at the 3D Viewport header, and you can

also enable it with the O key (Figure 4.32).
