The Select And Scale flyout on the main toolbar provides access to three tools you can use to change object size.
From top to bottom, these are:
In addition, the Scale command is available on the Edit menu and the Transform quadrant of the quad (right-click) menu; this activates whichever scale tool is currently chosen in the flyout.
The Select And Uniform Scale button, available from the Select And Scale flyout, lets you scale objects by the same amount along all three axes, maintaining the object's original proportions.
The Select And Non-Uniform Scale button, available from the Select And Scale flyout, lets you scale objects in a non-uniform manner according to the active axis constraint.
The Select And Squash tool is useful for creating different phases of the “squash and stretch”-style animation often found in cartoons. The Select And Squash tool, available from the Select And Scale flyout, lets you scale objects according to the active axis constraint. Squashing an object always involves scaling down on one axis while simultaneously scaling up uniformly on the other two (or vice-versa).
