A computer-implemented method for applying passive strain indicators to a component includes creating a plurality of surface curves and a plurality of data points on each of the plurality of surface curves, the plurality of surface curves and the plurality of data points defining the exterior surface of the component. The method further includes receiving data indicative of a user input selection of a selected surface curve of the plurality of surface curves, a selected data point of the plurality of data points on the selected surface curve, and a selected rotation angle. The method further includes determining an output dimension, location, and orientation of a passive strain indicator. The method further includes providing one or more control signals to a passive strain indicator application system to cause the system to apply the passive strain indicator having the output dimension, location, and orientation to the component.
