WORKING WITH OBJECTS

4. Press the Tab key to move to the Y value input box and enter 100↵.
5. Press Tab again to move to the Z input box and enter 75↵. The box is now slightly shorter
than it is wide and long.
The Select and Scale tool works in a slightly different way from the other two transform tools.
For one thing, a zero value in the coordinate readout doesn’t return the selected object to its original
shape. This is because the values in the coordinate readout represent percentages, where 100% is
the original size.
The Scale gizmo allows you to both uniformly and nonuniformly scale an object by automatically
switching between scale modes. Which operation you perform depends on which part of the Scale
gizmo you drag.
1. Try dragging the center of the Scale gizmo. You will see the object get uniformly bigger or
smaller, when you drag up or down.
2. This time, put your mouse over one of the edges of the Scale gizmo. When you drag over one
of the plane handles, you are performing a nonuniform scale in two directions at once. Look
closely at the gizmo and you can see the axes labeled. Try nonuniformly scaling the box in
the YZ plane.
3. The last operation you can perform using the Scale Transform gizmo is a nonuniform scale
in one direction. To accomplish this, put your mouse directly over the axis handle at the tip
How VIZ Sees the Scale Transform
Look at the box’s Length, Width, and Height values in the Parameters rollout in the command panel.
They all read 5´0.0˝ even though the box has been scaled. This is an important indicator as to how VIZ
handles object data. For example, if you have a box that is 1 unit long on each side and then scale it to
twice its size, VIZ does not now see this as a box that is 2 units on each side; it sees it as a 1-unit box with
a 200% scale factor applied.
