1. A system for converting graphic representations of three dimensional molecular models into computer-aided design format, the system comprising: a processor; and a memory having a set of instructions stored thereon, wherein the instructions, when executed, cause the processor to: receive, within a chemical structure rendering application, a request identifying a three dimensional model (e.g., of a chemical and/or biological structure), wherein the request is one of a file save request and a print request, associate the request with conversion to a computer-aided design format, access the three dimensional model, identify a surface region of a graphic representation of the three dimensional model, and convert the surface region into a polygon mesh representation.
