Abstract
A method and a storage device including a software product for designing a drilling pattern, and further a rock drilling rig, in the control unit of which a software product may be executed for designing the drilling pattern. For a group of holes of the drilling pattern, at least one master hole can be determined which comprises at least one dominating factor. The properties of at least one other drill hole are determined on the basis of the dominating properties of the master hole. A master hole may be a hole location master, hole depth master or hole direction master.
