Combined microstructure and object boundary representations of computer-aided design objects

A system comprising:

• a processor;
• and
• a non-transitory machine-readable medium comprising instructions that, when executed by the processor, cause a computing system to:
• define a computer-aided design (CAD) object in a CAD model as a combination of:
• an object boundary comprised of bounding faces that encapsulate the CAD object;
• and
• a microstructure that defines an internal geometry of the CAD object in a procedural representation, wherein the procedural representation is a representation of the internal geometry of the CAD object in a non-incarnated form;
• and
• incarnate, via the procedural representation of the microstructure, the internal geometry of the CAD object into a geometric representation to perform a CAD operation on the CAD object;
• and
• further perform a material-independent CAD operation on the CAD object without incarnating any portion of the microstructure, wherein the performance of the material-independent CAD operation does not depend on the internal geometry of the CAD object and wherein the material-independent CAD operation comprises a change to the object boundary of the CAD object.
