A method includes receiving 3D solid model data of a part to be manufactured, receiving at least one rule from a rules database, applying the rule to the 3D solid model data using a rules engine, and producing an output according the rule applied to the 3D solid model data. The rule can include an extraction portion which identifies elements or features of the 3D solid model data, a logic portion that applies a condition to the identified elements or features, and an action portion that defines an action to be performed to identified elements or features that meet the condition. The output can include an annotation of product manufacturing information to elements or features of the 3D solid model data that match the rule. ## Claims ### Claim 1 A method comprising: receiving, by a data processing system, 3D solid model data of a part to be manufactured; receiving, by the data processing system, at least one rule from a rules database; applying the rule to the 3D solid model data using a rules engine, by the data processing system; and producing an output according the rule applied to the 3D solid model data. ### Claim 2 (depends on 1) The method of claim 1, wherein the rule includes an extraction portion which identifies elements or features of the 3D solid model data, a logic portion that applies a condition to the identified elements or features, and an action portion that defines an action to be performed to identified elements or features that meet the condition. ### Claim 3 (depends on 1) The method of claim 1, wherein the rules database maintains a plurality rules, each maintained as a logical graph. ### Claim 4 (depends on 1) The method of claim 1, wherein applying the rule includes identifying elements or features of the 3D solid model data according to the rule, applying a condition to the identified elements or features according to the rule, and performing an action on the identified elements or features that meet the condition. ### Claim 5 (depends on 1) The method of claim 1, wherein the output is a listing or data structure of elements or features of the 3D solid model data that match the rule. ### Claim 6 (depends on 1) The method of claim 1, wherein the output is an annotation of product manufacturing information to elements or features of the 3D solid model data that match the rule, and the annotated 3D solid model data is stored in a 3D solid model for the part to be manufactured. ### Claim 7 (depends on 1) The method of claim 1, further comprising causing, by the data processing system, the part to be manufactured according to the output. ### Claim 8 (depends on 1) The method of claim 1, wherein the rule is received via an interaction with a user to define the rule as a rule logical graph in the rules database, and the output is produced in real time as the rule is defined. ### Claim 9 A data processing system comprising: a processor; and an accessible memory, the data processing system particularly configured to: receive 3D solid model data of a part to be manufactured; receive, at least one rule from a rules database; apply the rule to the 3D solid model data using a rules engine;
