You can easily further refine any of the vector paths in a shape by adding or removing anchor points, adjusting their roundness, making them sharp, and moving them. To edit the anchor points in a vector path, you first need to make the path editable.
Making a vector path editable lets you see and edit each of its points or add more points.
To exit editing, do one of the following:
Tip: If you’ve previously edited a vector path, you can double-click it to make it editable once again.
After you make a vector path editable, you can select one or more of its points to move, reshape, or remove them. An unselected point is outlined in red, while a selected one is solid red.
To select a single point, simply click it.
To select multiple points, do one of the following:
Tip: You can also reverse a selection of points so that any currently selected points are deselected and vice versa. To do that, press and hold theor keys while drawing a selection over a number of different points.
Sharp points have straight lines connecting to them, while smooth points have curved lines.
Tip: To sharpen or smooth all the points in a path,–click a vector path on the canvas (without making it editable) and choose Sharpen Path or Smooth Path from the shortcut menu.
When you move one direction handle of a smooth point, the opposite handle moves symmetrically so the two segments connect smoothly at that point. If you’d like to adjust the direction handles independently, you can disconnect them, turning the smooth point into an adjustable sharp point.
Divide lets you open closed paths (if you'd like to continue drawing, for instance) or split them into separate paths.
Note: To split a closed path into two open paths, make sure you select two points on the path. If you divide a closed path in one place only, you'll open the path instead of splitting it. When a path is split, the style of the original path (such as stroke weight, fill color, and shadows) applies to the newly created ones.
Open paths essentially become lines, so their stroke position is automatically reset to Center.
Join lets you combine paths onto a single path or you can use it to close the path completely and create a shape.
When open paths are joined, they are connected with a straight line going directly from endpoint to endpoint. To change the path shape, add additional vector points.
