Maya Basics Scaling objects
Scaling changes the size of objects or components. To use the Scale tool, you can click its icon in the Toolbox or press the R key. Drag the center box to scale the object uniformly on all axes at once,
or drag anywhere along each axis or box to scale along that X, Y, or Z axis. You can also select an axis or box, then middledrag anywhere in the scene to scale along it. To scale the object along a plane, click the plane handle and drag between the two axes you want,
or select a plane handle, then middledrag anywhere in the scene to scale along that plane. You don't even need to click on a box or plane handle directly: just press the Shift key and middledrag in the direction you want anywhere in the scene to scale the object along that axis. For example, if Manipulators display is off in the view, you can use this method to scale an object.
To change the size of the manipulators, you can use the plus (+) and minus keys (). You can also set the default manipulator size in the Preferences window: select Manipulators, and use the Global scale slider. Here, you can also set the default Handle size
and you can choose whether to show the Plane handles or not, and how much these handles are offset from the manipulator's center. If you want even more precise values than you get with the manipulators, you can use the Channel Box, which is covered in another tutorial.
If you want to change the settings for the Scale Tool, doubleclick its icon or click the Tool Settings icon in the upperright corner. You can also hold down the R key and click on the object to show the marking menu for the Scale Tool. This menu contains the same options that are available in the Tool Settings.
