Changing points and line segments
Each segment in a line has a control handle at either end, so at each interior
or "corner" point (where two segments join) you'll see a pair of handles.
The behaviour of these handles—and the curvature of the segments on either
side—depends on whether the point is set to be sharp, smooth, symmetric,
or smart. You can quickly identify a point's type by selecting it and then
checking to see which button is selected on the displayed context toolbar.
Each type's control handles behave differently as illustrated in the table
below.
To change one or more points to a different type:
1. Select the item with the
Select tool.
2. Click the
Edit Points button displayed beneath the item, then
click on the point you want to change (Shift-click or drag out a
marquee to select multiple points).
3. Click one of the point buttons on the displayed context toolbar:
A Sharp Corner means that the line segments on either side
of the point are completely independent. The corner can be
quite pointed.
A Smooth Corner means that the slope of the line is the
same on both sides of the point, but the depth of the two
joined segments can be different.
At a Symmetric Corner, points join line segments with the
same slope and depth on both sides of the point.
Normally, custom segments you draw with the Pen tool end in a
symmetric corner.
