While Rhino holds a large share of usage among designers and design firms, it lacks a comprehensive library of models that are built natively in Rhino. And when models are found, they tend to be miscellaneous visualization assets instead of integral architectural elements.
Partonomy is an ongoing effort to supply native Rhino models of architectural elements in the most convenient and streamlined way.
Partonomy offers 3 versions of the models for use in the viewport, Enscape or Vray. Every model is built to either be modular for easy assembly or fully parametric for customization. The models chosen by Partonomy are those that most important to architects and designers so that they can streamline their in house Rhino work without sacrificing accuracy or time.
