Make clicks land exactly on the drawing

Snapping makes your clicks land on something real. In this order: the ends and middles of your own measurements, then a corner of the drawing, a place where two of its lines cross, the middle of a line, and last the nearest point on a line. A click that lands two points out is invisible on screen and still in the bill, which is why snapping is on by default.

• Move the pointer near a corner and a marker appears. Click and the point goes exactly there.
• Hold Shift to hold a line exactly horizontal, vertical or 45°. It still snaps, but only to what lies on that straight run: the end slides along the line to the corner or line it meets, and never leaves the straight.
• Click Snap in the status bar to turn snapping off, for instance when you are tracing a curve.

1. Start a measurement and move the pointer towards a corner. A marker shows what it will land on.
2. Click while the marker is showing.
3. To place a point somewhere that isn’t on the drawing, click Snap in the status bar first, or hold Shift to constrain it.
