OG exemplary drawing
 
1. A computer-implemented method for generating a drawing of a spinal rod having a plurality of spline segments, comprising:
providing a computing system comprising a processor, a data store, and a patient specific planning and analysis module;
inputting a patient specific target plan comprising a digital representation of a spinal rod having a target geometry;
transforming the digital representation of the spinal rod into a curved line corresponding to the target geometry,
generating a spline data set comprising a plurality of spline segments, each spline segment being sequentially linked to an adjacent spline segment;
adjusting, iteratively, each spline segment until the plurality of spline segments approximate the curved line; and
generating, after the adjusting step is completed, a digital file comprising drawings for manufacturing a spinal rod based on the plurality of spline segments.
