Convert path segments to straight or curved points
Straight path segments are intersected
by corner points. Curved path segments contain curve points.
You can convert a straight segment to a curved segment and vice
versa by converting its point.
Convert a corner point to a curve point
In
the Tools panel, select the Pen tool.
Click a corner point on a selected path and drag away from
it.
The handles extend, curving the adjacent segments.
Note: To
edit the point's handles, choose the Subselection tool or press
Control (Windows) or Command (Mac) while the Pen tool is active.
Convert a curve point to a corner point
In the Tools panel, select the Pen tool.
Click a curve point on a selected path.
The handles
retract, and the adjacent segments straighten.
