Example: effects of the twist modifier on an object
Modifiers, as the name implies, modify an object's geometrical structure, deforming it in some way. For example, when you apply a Taper modifier to the end of a cylinder, the vertices near the end move closer together. A modifier makes changes in the geometry that stay in effect until you adjust or delete the modifier.
There are other general things to know about using modifiers:
You can apply an unlimited number of modifiers to an object or part of an object.
When you delete a modifier, all of its changes to the object disappear.
You can move and copy modifiers to other objects using controls in the modifier stack display.
The order or sequence in which you make modifications is important. Each modification affects those that come after it. Applying a bend before a taper can create a distinctly different result from doing so in the reverse order.
