Computer-aided manufacturing processes enable the landscape architect to complete the digital workflow from the idea to the physical prototype or the finished project component, not only as a model, but also as a built project. A conceivable workflow progresses from a first idea for a design solution to a digital sketch, e. g. on a tablet, and then to a CAD drawing or a digital three-dimensional model. This design can then be physically produced using computer-aided manufacturing processes – such as additive or subtractive manufacturing – in order to create the desired model, prototype, or finished project component. The fact that these physical-digital technologies continue to expand and grow suggests that it is also time to take a closer look at the design process. On the basis of a case study, I will examine how the existence of physical-digital technologies can affect the processes followed by designers. This paper discusses both benefits and risks. It deals with a formal aspect of design and must therefore be seen in a broader context of design activity (reflection, perception, thinking, expression). On the basis of the practical case study, it is possible to illustrate the potential of computer-aided manufacturing methods in landscape-architectural design processes and make this potential available through the applied method of analysis.
