Erase objects using a Wacom stylus pen eraser
When you flip a stylus pen, the Eraser Tool automatically becomes active. When you flip the stylus pen back over,
the last active tool becomes active again.
❖ Turn over the stylus pen and drag across the area you want to erase.
Press harder to increase the width of the erased path.
Eraser tool options
You can change the Eraser tool options by double-clicking the tool in the Tools panel.
Note: You can change the diameter at any time by pressing ] to enlarge or [ to reduce.
Angle Determines the angle of rotation for the tool. Drag the arrowhead in the preview, or enter a value in the Angle
text box.
Roundness Determines roundness of the tool. Drag a black dot in the preview away from or toward the center,
or enter a value in the Roundness text box. The higher the value, the greater the roundness.
Diameter Determines the diameter of the tool. Use the Diameter slider, or enter a value in the Diameter text box.
The pop-up list to the right of each option lets you control variations in the shape of the tool. Select one of the
following options:
Fixed Uses a fixed angle, roundness, or diameter.
Random Uses random variations in angle, roundness, or diameter. Enter a value in the Variation text box to specify
the range within which the brush characteristic can vary. For example, when the Diameter value is 15 and the
Variation value is 5, the diameter can be 10, or 20, or any value in between.
Pressure Varies in angle, roundness, or diameter based on the pressure of a drawing stylus. This option is most
useful when used with Diameter. It is available only if you have a graphics tablet. Enter a value in the Variation text
box to specify how much more or less the original value the brush characteristic will vary. For example, when the
Roundness value is 75% and the Variation value is 25%, the lightest stroke is 50% and the heaviest stroke is 100%.
The lighter the pressure, the more angular the brush
stroke.
Stylus Wheel Varies in diameter based on manipulation of the stylus wheel.
