Correcting the Lines
1To erase lines you have drawn, use the [Eraser] tool.
Select the [Eraser] tool from the [Tool] palette and select "Hard" from the [Sub tool] palette.
2Adjust the size of the [Eraser] tool.
Adjust the brush size of the [Eraser] tool either by moving the [Brush Size] slider on the [Tool Property] palette or by selecting a size on the [Brush size] palette. Setting a larger size allows you to erase a larger area at once, while setting a smaller size allows you to correct fine details.
3Move the eraser along the line to be erased.
Tips: Correcting a Line Using [Undo]
You can undo your last action while drawing by using [Undo] on the [Toolbar]. Use [Undo] to completely redraw a line or the [Eraser] tool to correct part of a line or an area containing multiple lines.
When using an iPad, you can undo operations by tapping the canvas with two fingers.
