The Eraser tools lets you drag the stylus to remove paint from a canvas plane in strokes. When a brush tool is active, the cursor becomes a crosshair with the letter P (paint), E (erase), H (hide), or S (show).
When you hold the cursor over a canvas plane, the cursor also displays a preview image of how the brush will apply paint to the sketch.
You can turn off the brush preview and radius indicator.
Drag the stylus on the canvas plane to begin sketching.
In the Paint Panel or Brush Options window do any of the following:
To apply paint as a brush, set Brush Mode to Paint or press and release F1.
To erase paint, set Brush Mode to Erase or press and release F2.
To hide paint, set Brush Mode to Hide or press and release F3.
To show hidden paint, set Brush Mode to Show or press and release F4.
Markers always apply paint and do not have a Brush Mode.
You can also set Brush Mode to smear paint (Smear), blur paint (Blur), sharpen paint (Sharpen), lighten paint (Dodge) or darken paint (Burn).
