Method for implementing design-for-manufacturability checks
First Claim
1. A method for implementing design-for-manufacturing checks during construction of a virtual model of a real part, the method comprising, at a computer-aided drafting engine executing on a computing device:
- receiving, at the computer-aided drafting engine, a manufacturing file specifying a set of available material stock-cross sections for a manufacturing facility;
in response to receipt of a first virtual feature for the virtual model at the computer-aided drafting engine, determining a first set of manufacturability scores for each of a plurality of stock orientations, comprising, for each stock orientation of the plurality;
identifying a first set of manufacturability errors associated with the stock orientation based on the first virtual feature, a corresponding material stock cross-section from the set of available material stock cross-sections, and the stock orientation, anddetermining a first manufacturability score for the stock orientation based on the first set of manufacturability errors, wherein the first set of manufacturability scores comprises the first manufacturability score for the stock orientation;
generating a first ranking for the plurality of stock orientations based on the first set of manufacturability scores;
selecting a first stock orientation from the plurality of stock orientations, based on the first ranking; and
presenting, at the computer-aided drafting engine, a first manufacturability error of the first set of manufacturability errors associated with the selected first stock orientation.

Abstract
One variation of a method for implementing design-for-manufacturing checks during construction of a virtual model of a real part includes: in response to insertion of a virtual feature into the virtual model, estimating a minimum stock geometry for the real part based on the virtual feature; selecting a first material stock cross-section from a set of available material stock cross-sections of a material designated for the real part based on the minimum stock geometry; at a first time, prompting a user to adjust a dimension of the virtual feature to enable production of the real part with a second material stock cross-section in the set of material stock cross-sections, less than the first material stock cross-section; at a second time succeeding the first time, submitting, to a manufacturing facility and over a computer network, an order for production of a unit of the real part according to the virtual model.
