Pencil and Eraser
The Pencil tool is usually used to draw free-form lines on PDF document pages and the Eraser tool is used to erase parts of the pencil markups that you’ve drawn.
To mark up with the Pencil tool:
- Choose Comments > Draw Tools > Pencil, or select the Pencil tool in the Comment toolbar.
- Move the pointer to where you want to begin drawing. You don’t have to use one unbroken stroke. You can release the mouse button briefly, move the pointer to a new location, and continue drawing.
To edit the pencil markup:
- To change the line thickness, color and opacity, right-click the drawing and select Properties from the context menu. Select the options you want from the Pencil Properties dialog box. See Setting Comment Properties.
- To erase parts of the drawing, choose Comments > Draw Tools > Eraser or select the Eraser tool on the Comment toolbar. Then drag across the areas of the drawing you want to remove.
