Modifying Shapes with the Sub-Selection Tool
Vector shapes are made up of anchor points connected by line segments. There are two types of anchor points: corner points and curve points. Corner points connect two line segments in a sharp angle such as the corner of a square. Curve points define a curve or positions along a straight line and can be modified with Bézier handles. These handles extend out from the curve point and allow for very precise modification of the shape of the curve. The Sub-Selection tool works hand-in-hand with the Pen tool to create and modify shapes and lines in this way.
Use the Sub-Selection Tool to Modify a Shape
Create a simple oval shape using the Oval tool.
Click the Sub-Selection tool on the Tools panel.
The pointer becomes an empty (or white) arrow.
Click on the edge of the shape to reveal the anchor points, and then click on an anchor point to select it or drag a selection rectangle to select multiple anchor points.
The anchor points are the little white squares around the edge of the shape. When selected, Bézier handles appear on either side of the anchor point.
Grab one of the handles or the anchor points themselves and drag it, and then release the mouse.
