Abstract
An execution height setting system 100 includes laser device 102 for setting a horizontal reference plane by rotatably radiating a laser beam and a execution height display device 104. The execution height display device 104 has a light receiving section 112 for receiving the laser beam, an indexing section 118 for indicating a shift of the sensed laser beam relative to the reference position, and a data display section 108 for displaying the inputted grade or execution height. As the execution height display device 104 receives the laser beam, it senses the distance between the laser device 102 and the execution height display device 104 and then computes the desired execution height based on the set grade value. The computation result for the execution height is displayed on the execution height display portion 108c.
