• All transformation tools work on paths or groups of points, not single points.
• You must first select a path or group of points to transform, then use a transformation tool on it.
• So option-click a path to select all of it before transforming, or select just the points you wish to transform.
• Or, use the marquee and group multiple objects before transforming.
• You can also use Select All in the Edit menu , then group, to transform your entire drawing. This would be useful if, for instance, you wished to resize your illustration.
