Pencil
Shortcut N

The pencil in hand with its bar, normal, merge, subtract and tolerance, and two freehand strokes

The gesture

You press, drag, release: the stroke is the route the pointer took, turned into a smooth curve (not a polyline of hundreds of tiny pieces). The Pencil does not snap.

  • If you release within 15 pixels of where you started, the stroke closes: it is a closed shape, and it takes the fill of the style. Left open, it stays a line.
  • A stroke shorter than 6 pixels is not created.
  • The Pencil stays selected, and the stroke you just placed stays selected.

The bar

OptionWhat it does
normalthe stroke is placed as it is
unitethe stroke is united with the shape it touches
subtractthe stroke is cut away from the shape it touches
tolerancehow much the trace is simplified, in screen pixels; 2 by default. At zero every sample is kept

In unite and subtract, the stroke determines the target: the first shape under the points it passed over. Stroke and shape become a boolean operation, which takes the place and appearance of the shape, and stays selected. Nothing underneath? The stroke is simply placed. A group or a text cannot go into a boolean operation.
