After calibration, you can create individual measurements over the source.
Available tools include:
- length,
- curve,
- area,
- rectangle,
- arc,
- angle,
- circle.
Point placement accuracy
Place measurement points at geometrically unambiguous locations. At high zoom levels, it is useful to snap to helper geometry and, in PRO, to the pixel grid.
Shift / Ortho
For selected tools, the Shift key can lock the horizontal or vertical direction.
