With the Vector Brush Tool you can create a hand-painted look by painting freehand, variable width, lines and shapes as if you were painting on paper. Its vector characteristics means you can edit the stroke at any time.
The Vector Brush Tool paints by scaling or repeating an image along a path (line).
As you paint, nodes are created automatically and can be edited with the Node Tool.
The tool uses a soft, round brush as default. Other vector brushes can be selected from the Brushes Studio.
