Editing Bézier Handles
For Bézier polylines, each control point has two direction handles that adjust the slope of a
curve through the control point. These direction handles appear only when the point
is selected.
Dragging a direction handle makes adjustments to the curve of the segment that emerges from
the control point. The direction handle on the opposing side of the control point will also move
to maintain the relationship between these two handles.
To break the relationship between direction handles and adjust one independently, hold
Command while dragging a handle. Subsequent changes will maintain the relationship, unless
Command is held during each adjustment.
Hold Command to adjust one
handle independently.
If you want to adjust the length of a handle without changing the angle, hold Shift while moving
a direction handle.
Point Editor
The Point Editor dialog can be used to reposition control points using precise X and Y
coordinates. Pressing the E key on the keyboard will bring up the Point Editor dialog and allow
you to reposition one or more selected control points.
The Point Editor dialog can be
used to position control points.
The dialog box contains the X- and Y-axis values for that point. Entering new values in those
boxes repositions the control point. When multiple control points are selected, all the points
move to the same position. This is useful for aligning control points along the X- or Y-axis.
If more than one point is selected, a pair of radio buttons at the top of the dialog box
determines whether adjustments are made to all selected points or to just one. If the Individual
option is selected, the affected point is displayed in the viewer with a larger box. If the selected
point is incorrect, you can use the Next and Previous buttons that appear at the bottom of the
dialog to change the selection.
