Abstract This paper describes the construction of an information flow that combines parametric modelling and genetic algorithms to optimise both the total weight of a structured steel roof and the shape of its surface to maximise the generation potential of photovoltaic energy. Through the systematisation of a design process using genetic algorithms integrated with generative design as an architectural design method, architects can work with problem parameterisation, going one step further than the mere formal proposition of solutions.As a result, we present a process in which there is a dialogical relationship between the architect and project in a continuous flow of information in the initial steps of the design process, guided by predefined optimisation objectives. Therefore, it is relevant to note that the designer accepts a reduced creative control over the final shape in favor of control over the core principles that constitute the optimisation algorithms. An approach that involved the designer in a process of post computational processing evaluations is also highlighted, giving him better support to discuss and analyze the design options.

In this study, a design methodology based on prototyping is proposed. This design methodology is intended to enhance the functionality of the test, differentiating it from the prototyping that is being conducted in conventional architectural design projects. The objective of this study is to explore reference cases that enable designers to maximize the utilization of both digital models and physical models that have been currently used in architectural designs. Also, it is to explore the complementary roles and effects of digital models and physical models. Smart Building Envelopes (SBEs) are one of challenging topics in architectural design and requires innovative design process included tests and risk management. A conceptual prototyping-based model considering the topic is applied to the design studio (education environment in university). Designing SBEs is not difficult to conceive ideas, but it is impossible to “implement” using the conventional design method. Implementing SBEs requires to strengthen validities and improve responsibilities of ideas in the stages of architectural designs, with cutting-edge technologies and smart materials. The design methodology enables designers (represented by students) to apply materials and manufacturing methods using digital models (parametric design, simulation, BIM) and physical models, rather than representing vanity images that are considered simple science fiction.

Globoidal indexing cam mechanism is the spatial indexing mechanism of high speed, high precision and widely used in modern machine and automatic production line.But the working profile of the globoidal indexing cam mechanism is not fair for the space curved surface and it is difficult to model. The traditional design method requires a great deal of calculation, and the design process is complexed, we have to repeat the entire design process when changing any parameters, lead to low design efficiency and poor universality. To solve above disadvantages, this paper used the space meshing principle and space coordinate transformation method, based on 3 d modeling software Pro/ENGINEER, using vc + + and Pro/toolkit for secondary development, realize the parametric modelling of globoidal indexing cam mechanism, and the simulation and analysis of the generated cam mechanism.

<p><br clear="none"/></p><p>During the optioneering phase, engineers face the challenge of choosing between myriads of possible designs, while, simultaneously, several sorts of constraints have to be considered. We show in a case study of a 380 m long viaduct how parametric modelling can facilitate the design process. The main challenge was to satisfy the constraints imposed by several different stakeholders. In order to identify sustainable, aesthetic, economic as well as structurally efficient options, we assessed several key performance indicators in real time. By automatically estimating steel and concrete volumes, a simple, yet suitable approximation of the embodied carbon (considering 85-95%) can be obtained at a very early design stage. In summary, our parametric approach allowed us to consider a wider range of parameters and to react more flexibly to changing conditions during the project.</p><p><br clear="none"/></p>

According to the different fellower structure and general simple trapezoid motion law of cam mechanism, this paper established a mathematic model for the motion of fellower structure of cam mechanism. The design method of motion law of the fellower structure was introduced, and the law of motion transition of fellower system and the related issues with program design were studied. A design system was developed using VB code based fellower structure and general motion laws. And the system could solve the curve of motion law for the fellower system and the eigenvalue of the curve, and finally realize parametric design of motion law for the fellower structure of cam mechanism. And the system could calculate and output the coordinate of cam configuration, and improve the digitized design process of cam parametric. The interface of the designed system is friendly and convenient, and the system could be used in both engineering and teaching.

In the era of digitization, parametric design creates new possibilities for its application in areas such as architecture and design as well as landscape architecture. However, it requires tools that can not only facilitate the design process, but also reduce its time consumption. The purpose of the article is to review the software used for parametric design supporting the work of landscape architects. The selected, most popular programs and plugins used by architects and designers, which are also indirectly used by landscape architects as well as software dedicated directly to landscape architects, were evaluated. Most of the discussed software has options for parametric design, while they only apply to selected elements. Due to the interdisciplinary character of landscape architecture, there is currently no single multifunctional program giving the possibility of comprehensive application of parametric design options to all aspects of a complex project. For this reason, landscape architects are forced to combine functions themselves using several of programs. This is a significant difficulty in carrying out the design process.

<p>Architects use computers predominantly to digitise a design process that has been in use prior to the advent of the computer. Traditional analogue concepts are transferred into and sculpted through the digital world but the overall process has remained mostly unchanged for decades. Merely digitising a known process does not utilise the full power of the computer and its near limitless ability to compute.  For an architect, design of the built environment is highly important especially if they are to optimise the physical, phenomenological and psychological aspects of the space. The process of designing an architectural space is riddled with possibilities or variables that architects have used historically to aid in the design of the built environment, including but not limited to: object relationships, climate, site conditions, history, habitibility and the clients input - all project requirements that must somehow be quantified into a built object. This information is key for an architect as it will inform and form the architecture which is to be designed for the project at hand.  This information, however useful, is not easy to integrate into every aspect of the design without intensive planning, problem solving and an exploration of almost an infinite number of possibilities. This is where parametric design can be used to aid in the design. More of the fundamental aspects of the information gathered in a project can be programmed into a computer as parameters or relationships. Once this information has been quantified, the designer can run through iterations of a design which are defined by these parameters. This is not a random process. It is controlled by the designer and the outcome is a product of how the architect designs the parameters, or relationships between components of the design.  Parametric design offers a shift from merely digitising design ideas to using programmed constraints derived through the design process to influence and augment the design envisioned by the architect. Parametric design allows the system to be changed holistically and updated through the alteration of individual components that will then impact the form of the design as a whole – creating a non-linear process that is connected throughout all design phases.  This thesis seeks to explore parametric design through its implementation within a group design project to decipher how a parametric process grounded in an understanding of contemporary digital fabrication can inform architectural space. To explore parametric design, this thesis will practice this re-envisioned design process through three design phases. The first phase is the foundational knowledge stage where the applications of digital workflow, computer models, tools and material explorations are examined. Second is the production of a prototype to investigate lessons learnt from phase one and apply these lessons to an actual parametric system used to design a prototype. The final stage will be a developed design process that will further explore a parametric system and its architectural applications. These phases will be developed through a series of prototypes in the form of material explorations and scale artefacts which will explore how it would be used to address many of the designs facets from sensual to corporeal.</p>

The design processes and strategies applied to each architect in carrying out their design tasks are different. The stages in producing architectural work can be based on the theory of certain design methods, intuition or design experience from each architect. As an architect, it is mandatory to know the design process in accordance with existing methods. There are several variables in the design method according to Jones and Schmitt. And this study aims to find the variables most widely used by 8 architects in designing. Including the average of the variables it uses. The method used in this research is quantitative method with one way ANOVA (analysis of variant) as its statistical analysis, by examining the mean difference between the research objects. The literature study was used to obtain an analysis of the design process and the methods used by 4 well-known architects as their secondary empirical data source, while field observations in the form of direct interviews were carried out to obtain the reality of the design process for 4 local architects with various backgrounds and characteristics as well as different architectural works. The end result shows that the average level of architects in the use of research variables is not much different and the design process variables that are most often used by architects in carrying out architectural designs, are the clarity of the need for the design function, the use of the drawing system and the design results that are meaningful and logical.

Parametric designing, its instruments, and techniques move architectural design education towards novel avenues of deep learning. Akin to learning and working environments of engineering and manufacturing, it offers similar advantages for architects. Yet it is not as simple as using another tool; parametric designing fundamentally shifts the engagement with the design problem. Parametric designing allows architects to be substantially deeper involved in the overall design and development process extending it effectively beyond production and lifecycle. Leaning parametric design strategies enhance architects’ critical engagement with their designs and their communication. Subsequently, the computational aid of parametric modelling alters substantially how and what students learn and architects practice.

Structural project is based on technical regulations, structural codes, construction conditions, and client requirements. Through the structural design process, some important decisions that can significantly affect the final result must be implemented. The most important factor for optimal design is the reduction in material and overall work costs. Selecting appropriate joint configurations that can reduce the overall weight and work on the structure is critical. To examine a significant number of possible configurations and their effect on structural behavior, the generative design method (GDM) is used. In this study, software is custom developed, and a relevant example of generative joint structural design is provided. The methodology for the optimal joint and structure design is described comprehensively. The final results show that the GDM is an effective methodology for application in the design of steel structures.
