Method and arrangement for inspection and cutting to length of lengthwise objects such as timber trunks 10", where the measurement object is placed stationary against an indication beam 13 with a plurality of indication elements such as light diodes 13a at uniform mutual spacing i. By operating a stick 16a, the light diodes are turned on and off in sequence and when the light/dark boundary reaches an intended cutting site, a signal is triggered which drops a stopping shoulder 31, 32, 33 at a cutting station K via a computer layout 30.
