In the field of Generative Design (GD),Visual Programming Languages (VPLs), such as Grasshopper, are becoming increasingly popular compared to the traditional Textual Programming Languages (TPLs) provided by CAD applications, such as RhinoScript.This reaction is explained by the relative obsolescence of these TPLs and the faster learning curve of VPLs. However, modern TPLs offer a variety of linguistic features designed to overcome the limitations of traditional TPLs, making them hypothetical competitors to VPLs. In this paper, we reconsider the role of TPLs in the design process and we present a comparative study of VPLs and modern TPLs. Our findings show that modern TPLs can be more productive than VPLs, especially, for largescale and complex design tasks. Finally, we identify some problems of modern TPLs related to portability and sharing of programs and we propose a solution.

Algorithmic BIM (A-BIM) is a design paradigm that merges the potentialities of both Algorithmic Design (AD) and Building Information Modelling (BIM). This paper describes how the A-BIM approach was integrated into the design workflow of two traditional design studios, to develop a set of parametric facades for a residential building, from which we automatically extracted material quantities and construction details. This work demonstrates how the combination of AD with BIM influenced the whole design process and the selection of the final solution. The limitations found during the entire process are also addressed, such as tight deadlines and financial constraints. Finally, the pros and cons of using an A-BIM process compared to a traditional BIM approach are discussed, as is the implementation of this paradigm in a traditional design practice. We also show how the efficiency of the A-BIM process can be greatly increased by the use of an Integrated Development Environment for AD supporting the generation of 3D models in both Computer-Aided Design (CAD) and BIM applications. Highlights Combines algorithmic design with BIM in the context of a traditional design studio. Uses a portable CAD/BIM algorithmic tool to speed up the design exploration. Uses algorithmic design to optimize the production cost of a facade design. Automatically generates the corresponding technical documentation.
