Free GRAPPA Addin for Revit - Automatically Generate Floor Plans Using Palladian Grammar

GRAPPA is an implementation of "The Palladian Grammar" by  Stiny and Mitchell (1978). The approach is based on graph grammars as described by Grasl (2012).

The Palladian grammar is a well-known example of a shape grammar. These can be used to systematically describe bodies of design. Here the rules that are used during the design generation can either be applied individually or they can be applied using a simple random generator.

This project demonstrates how shape grammars can be implemented for the automatic generation of designs.
