To convert a smooth point to a corner point with independent direction lines, drag 

either direction point.

Converting a smooth point to a corner point

You can modify the shape of a path by moving any of its anchor points or by moving the 
direction points of direction lines attached to a curve segment. Editing existing segments 
is slightly different from drawing them. Keep the following guidelines in mind as you 
adjust existing segments:

If an anchor point connects two segments, moving that anchor point always changes 

both segments.

When drawing with the pen tool, you can temporarily activate the last used selection 

tool by holding down Ctrl (Windows) or Command (Mac OS) so that you can adjust 
segments you’ve already drawn.

When you draw a smooth point with the pen tool, dragging the direction point 

changes the length of the direction line on both sides of the point. However, when you 
edit an existing smooth point with the direct-selection tool, you change the length of 
the direction line only on the side you’re dragging.

With the direct-selection tool  , drag the anchor point on either end of a segment. 
Shift-drag to constrain the adjustment to multiples of 45 degrees.

If you’re simply trying to make a rectangle wider or narrower, it’s easier to select it 
with the selection tool and resize it using one of the handles on the sides of its 

bounding box.

1 Using the direct-selection tool  , select the anchor point on either end of a curved 
segment. Direction lines appear on the anchor point and on the adjacent anchor points, 
if present (some curved segments use just one direction line).

2 Do one of the following:

Drag the anchor point. Shift-drag to constrain movement to multiples of 45 degrees.
