Freehand Draw Tool
To draw freehand in the SVG document, click and drag the pointer freely in the work area.
The shape to be drawn can be added (Boolean operation) to an already drawn and selected shape.
To add the shape to be drawn to a selected shape (path), hold down the "ALT" key during the drawing phase.
The shape to be drawn can be used as a subtraction (Boolean operation) from a shape that has already been drawn and selected.
To use the shape you intend to draw as a subtraction from a selected shape (path), hold down the "ALT + SHIFT" key during the drawing phase.
This tool can be activated via the keyboard by pressing the "N" key.
