A method includes disposing an intervention service tool within a tubular. The intervention service tool includes an anchoring system, a shifting system, and a linear actuator system. The tubular includes a shifting profile geometry disposed within the tubular at a first location. The anchoring system, the shifting system, and/or the linear actuator system is actuated. Shifter system pressure, linear actuator system force/pressure, and displacement of the shifting system is measured. A known graph of the shifting profile geometry is compared to one or more of a measured pressure, a measured force, or a measured displacement. A position of a key disposed on the shifting system is determined relative to the shifting profile. The shifting profile geometry is engaged with the key based on the position of the key. The shifting profile geometry is positioned at a second location that is different from the first location.

A material modification assembly comprises an energy source for generating light beams to modify a substrate. A computing device generates pattern script(s) based on at least one parameter of the modification. The computing device also generates process script(s) including a type of pulse scripts to be used with the light beams and are based on at least one parameter of the interaction between the energy source and the substrate.
