A Study for Parametric Morpho-Semantic Operators to Assist Architectural Conception at the Drafting Stage

In this paper, we make the assumption that a shape modelling process can rely on the application of a set of morpho-semantic operators to initial shapes. In this paper, we refer to several researches which have attempted to identify such operators. We will attempt to validate this concept through the analysis of some ''innovative" buildings. Thus, in different projects of contemporary architects, we can find the trace of some transformations (e.g. "twist", "merge", "overlay", etc.) recorded in the final geometry. These transformations have a symbolic representation. A design system based on the combination of these operators could enable the designer to quickly explore a great number of spatial solutions

1. Introduction

Since the early 80's, CAD tools have provided us with new means of graphic representation in architecture. Contrarily to the usual manner in which spatial forms are represented in a 2D “glance” [in sections, elevations and plans], by using this 3D drawing software, one is provided directly with a virtual 3D model “constructed” by the computer.
