1. A method of modeling a part for 3-D printing, the method comprising:
determining a first volume of the part;
modeling the first volume using a 3-D computer-aided design (CAD) model;
determining a second volume of the part;
modeling a complex geometric feature (CGF) within the second volume using parametric modeling based on 3-D printing parameters, wherein the CAD model of the first volume and the parametric model of the CGF are independently compiled and not constrained by one another; and
determining independent instructions for 3-D printing portions of the part based on separate processing of the CAD model of the first volume and the parametric model of the CGF during 3-D printing of the part.
