Curve fit: Available from within the Freehand Pen Options dropdown while the Freehand Pen Tool is selected. Value entered determines the accuracy to which bezier handles will be added to your freely drawn path. The higher the value, the more accurate your result will be. A value of between 0.5 and 10 pixels is required.

Magnetic: Available from the Options bar and within the Freehand Pen Options dropdown while the Freehand Pen Tool is selected. When selected, paths drawn will magnetize to pixels. The Magnetic settings as shown below, determine the width of the area the path is prepared to jump across, the contrast of the pixels necessary to attract the path and the frequency of anchor points added to the path.

7. Other Shortcuts and Tips

(With path selected) Spacebar to give you access to the Hand tool. Move your screen without deselecting the path or changing tools.

Go to View > Snap To > Grid to allow precise creation of curves with the Pen Tool.


8. Best Practice Suggestions

Drag handles from the first anchor point when beginning a curved path.

Drag your handles around just one third of the curve youre creating for a smooth path.


Position anchor points on a curve where the paths begin to change direction, not in the middle of its curve.



Be sparing with your use of anchor points, fewer points = neater path.
