Paintbrush Tool
– Hotkey N/A
– The Paintbrush Tool is used to create free-form paths that can have a more hand-drawn feel. With the Paintbrush Tool, you can draw a path and apply a brush to the stroke at the same time to give paths an artistic look, like calligraphy, for instance.
– Select either the Paintbrush or Pencil Tool in the Toolbar. Click “Tool Options” in the Properties panel or double-click the Tool in the Toolbar. You can select options for how the tool works in this dialog box.
– With either tool, an asterisk appears next to the pointer, indicating that you can draw a new path. Drag to start drawing.
– With the Paintbrush Tool selected, you can apply a different brush by choosing it from the Brush menu in the Properties panel before drawing a path or after (with the path selected).
– To redraw parts of a path with either tool, move the pointer over a selected path. When the asterisk disappears, drag and redraw.
