Abstract: A controller for an excavating machine, comprising a tool, an arm, a set of sensors and a chassis. The sensors being configured to provide data regarding a pose of the tool. The controller comprising an input interface and a computing unit. The input interface is configured to receive operator steering commands. The computing unit is configured to read a design model, comprising two interconnected polygons defining a breakline and to reference the pose of the tool to the design model. The controller is configured for performing a semi-automatic breakline-transition. The semi-automatic breakline-transition function including identifying a breakline-transition move based on the operator steering commands and the pose of the tool with respect to the breakline and generating operator steering command adjustment commands, based on the pose of the tool and the operator steering commands, in order to align the tool to the breakline.
