Before we go any further, I need to briefly explain the
purpose of Modifiers and the Modifier
Stack.
Modifiers are what you use to carry out all of the more complex modifications to models. Extrude is an an example of a Modifier. Some other basic Modifiers are Bend, Twist, Taper and Lathe. So you get the idea. You add modifiers to an object by selecting the object, and then selecting the modifier you want from the Modifiers Drop-down in the Modify Panel. Each Modifier you add to an object is stored in the Modifier Stack:
This is literally a stack of modifiers. The beauty of this method of applying modifiers is that it is non-destructive. You can move up and down through the stack and turn modifiers on and off. If at any point you decide that you want to remove a modifier, you can do so without affecting the other modifiers you have added since. To move through the stack, you simply select the modifier you wish to work on. Once a Modifier is selected, you can either: edit the Modifier parameters via the rollouts, toggle it on or off - or delete it - I'll leave it at that for the time being. There's lots more to know, but you just need to know enough to understand what Modifiers are and how you use them. Read "Chapter 6: Modifying Objects" in the recommended text to learn more. |
