Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design and manufacture of physical structures using toolpath generation by demonstration include, in one aspect, a method including: receiving a user specified path traced in reference to geometry of a modeled object to be manufactured by a computer-controlled manufacturing system, wherein the user specified path is a spatial representation of a desired toolpath; synthesizing candidate toolpaths for the geometry of the modeled object using variations of at least one toolpath parameter; measuring similarities between the candidate toolpaths and the user specified path, including comparing at least a spatial similarity between the candidate toolpaths and the user specified path; suggesting at least some of the candidate toolpaths based on the measured similarities; and determining a toolpath for use when manufacturing the modeled object in accordance with user input regarding the at least some of the candidate toolpaths.
