Artykuł podejmuje problematykę optymalizacji procesu projektowania konstrukcji żelbetowych w odpowiedzi na wyzwania stawiane przez koncepcję Przemysłu 4.0. Tradycyjne, sekwencyjne metody modelowania na styku środowisk CAD i MES zastąpiono autorskim algorytmem opartym na projektowaniu parametrycznym (AAD) w środowisku Grasshopper. Opracowane rozwiązanie integruje automatyczne generowanie układu prętowego trzystrefowego budynku laboratorium z modułem inteligentnej aplikacji obciążeń klimatycznych i użytkowych, bazującym na topologii obiektu. Skrypt przeprowadza wstępną optymalizację materiałową przekrojów z wykorzystaniem silnika Karamba3D, a następnie realizuje bezstratny transfer kompletnego modelu analitycznego do docelowego programu obliczeniowego Dlubal RFEM 6. Przeprowadzona analiza porównawcza sił wewnętrznych potwierdziła wysoką zbieżność i rzetelność uproszczonego modelu statycznego. Wykazano, że algorytmizacja drastycznie redukuje czas niezbędny do wdrażania zmian koncepcyjnych oraz eliminuje błędy transferowe.

The article addresses the optimization of the reinforced concrete structural design process in response to the challenges posed by the Industry 4.0 paradigm. Traditional, sequential modeling methods at the interface of CAD and FEM environments have been replaced with a proprietary algorithm based on Algorithmic Aided Design (AAD) within the Grasshopper environment. The developed solution integrates the automated generation of a three-zone laboratory building’s spatial frame with a module for the intelligent application of climatic and live loads, based on the object’s topology. The script performs preliminary material optimization of cross-sections using the Karamba3D engine, followed by a lossless transfer of the complete analytical model to the target structural analysis software, Dlubal RFEM 6. A comparative analysis of internal forces confirmed the high convergence and reliability of the simplified static model. It has been demonstrated that algorithmization drastically reduces the time required to implement conceptual changes and eliminates transfer errors.

Maksymalizacja naturalnego oświetlenia odgrywa kluczową rolę w projektowaniu budynków mieszkalnych, wpływając na komfort użytkowników, redukcję zużycia energii oraz poprawę jakości przestrzeni wewnętrznych. Tradycyjne metody oceny nasłonecznienia, takie jak podejście Mieczysława Twarowskiego, oferują sprawdzoną i wiarygodną podstawę analityczną. Jednak rozwój technologii cyfrowego modelowania informacji o budynkach (BIM) pozwala na znacznie bardziej zaawansowane podejście do optymalizacji oświetlenia naturalnego, otwierając nowe możliwości w zakresie projektowania. Metodyka modelowania parametrycznego, oparta na narzędziach, takich jak Rhino z modułem Grasshopper lub Revit z modułem Dynamo, w połączeniu z algorytmami iteracyjnymi, umożliwia wielowymiarową analizę nasłonecznienia. Dzięki temu projektant może przeprowadzać precyzyjne symulacje oświetlenia w różnych wariantach projektowych, uwzględniając zarówno sezonowe zmiany nasłonecznienia, jak i specyfikę lokalizacji. Świadome wybory projektowe pozwalają na stworzenie optymalnych rozwiązań, które maksymalizują dostępność światła naturalnego przy jednoczesnym spełnieniu wymogów estetycznych, funkcjonalnych i energetycznych, czyniąc budynki bardziej zrównoważonymi oraz przyjaznymi dla ich użytkowników. W artykule przedstawiono rezultaty wykorzystania narzędzi modelowania parametrycznego w celu uzyskania najlepszej struktury funkcjonalnej projektowanego budynku z naciskiem na dostępność oświetlenia naturalnego.

Maximizing natural lighting plays a key role in residential building design, impacting user comfort, reducing energy consumption, and enhancing the quality of interior spaces. Traditional methods of assessing sunlight exposure, such as the approach developed by Mieczysław Twarowski, provide a proven and reliable analytical foundation. However, the development of Building Information Modeling (BIM) technologies allows for a much more advanced approach to optimizing natural lighting, opening up new possibilities in architectural design. Parametric modeling methodology, based on tools such as Rhino with the Grasshopper plugin or Revit with the Dynamo module, combined with iterative algorithms, enables multidimensional sunlight analysis. This allows designers to perform precise lighting simulations across various design scenarios, taking into account both seasonal changes in sunlight and the specific characteristics of the building’s location. Informed design choices make it possible to create optimal solutions that maximize the availability of natural light while meeting aesthetic, functional, and energy efficiency requirements-making buildings more sustainable and user-friendly. This article presents the results of using parametric modeling tools to achieve the best functional structure for a proposed building, with a focus on maximizing access to natural lighting.

This article presents a study of the application of generative artificial intelligence (AI) in the early architectural design phase. Its purpose is to verify whether these tools speed up the development of a concept and how to increase control through simple parametric models and a clearly defined decision loop including a human. The study was based on a course taught at the Faculty of Architecture of the Warsaw University of Technology by a team of teachers from the Chair of Architectural Design and the Department of Pro-Environmental Design. The course was attended by 62 students in 25 teams. The course was divided into four blocks (type exploration and visualisation, automation of functional layout generation, insolation analysis and life cycle assessment) - the first of these is described in detail in this article. The course combined parametric modelling with a text- and image-driven image generator. The results of student surveys conducted at the end of the course indicate that AI was useful at the concept stage for 88% of them; the main barriers were limited predictability, repeatability and hardware requirements. The best results were produced by a combination of a clearly defined designer’s intention with a simple 3D model and a critical selection of results. The course authors recommend integrating AI into the curriculum as a way to learn to work with the process (formulating criteria, controlling the course, evaluating the results), rather than only operating result-focused tools.

The study presented in this paper was carried out to verify the effectiveness of the individually developed acoustic optimisation method. Documentation and own measurements of an existing post-industrial building - a grain elevator in Płock - were used. The method of iterative search for the geometric form of the interior was used to design a concert hall inscribed in its structure. The criteria for assessing the quality of the generated solutions were the acoustic parameters obtained (reverberation, initial time delay gap, uniform coverage of the auditorium with reflected sound, and the quotient of the hall volume and the number of seats in the auditorium). As a result of the optimisation, variants of the auditorium’s interior design were created. These were evaluated against reference architectural realisations. The results of the study allowed the authors to confirm the effectiveness of the method (the optimisation results were in line with the reference halls in many points). They also provided a picture of the existing limitations, being a premise for further improvements to the method. The authors intend to use the results in further work on parameterisation of architectural models and on the use of generative engines in optimisation. In the longer term, after refinement, there is a chance to use the method in real creative activities.

Artykuł przedstawia zasady projektowania zwierciadeł akustycznych w przestrzeni publicznej, ukierunkowane na nadanie im jednoznacznej afordancji funkcji interaktywnej. Celem badań było określenie, w jaki sposób krzywizna, refleksyjność i sposób posadowienia wpływają na intuicyjne rozpoznawanie działania obiektu. Badania przeprowadzono w formule research by design, wykorzystując iteracyjne modelowanie geometryczne, analizy materiałowe i ocenę wariantów integracji z podłożem. Wyniki wskazują, że powierzchnie o wysokiej refleksyjności wzmacniają percepcję wklęsłości czaszy i sprzyjają kojarzeniu obiektu ze zjawiskiem odbicia dźwięku. Podwójna krzywizna – wklęsła robocza i wypukła paraboloidalna – poprawia czytelność sylwety i łączy wymagania akustyczne z komunikatywnością formy. Zastosowanie wycinka eliptycznego obniża strefę ogniskową i zwiększa powierzchnię odbicia, poprawiając ergonomię użytkowania. Zintegrowane posadowienie ogranicza skojarzenia z urządzeniami technicznymi i wzmacnia jednorodność bryły. Opracowany zestaw zasad może stanowić podstawę dalszych analiz nad modelowaniem interaktywnych obiektów w przestrzeni publicznej.

The article presents design principles for acoustic mirrors in public space aimed at achieving clear affordance of their interactive function. The study examined how curvature, reflectivity and ground integration influence the user’s intuitive understanding of the object prior to interaction. The research was carried out within a research-by-design framework, using iterative geometric modelling, material analyses and evaluation of anchoring variants. The results show that highly reflective surfaces enhance the visual legibility of the concave dish and support associations with sound reflection. Dual curvature – the functional concave surface and the convex paraboloidal shell – improves silhouette recognisability and balances acoustic performance with visual communicativeness. The elliptical trimming lowers the focal zone while increasing the reflective area, improving ergonomics. Integrated ground anchoring reduces associations with technical devices and reinforces the coherence of the form. The proposed design principles provide a basis for further studies on modelling interactive objects in public space.

The emerging trend of employing 4 or more axes multi-purpose and gantry industrial robots in large format additive manufacturing presents numerous opportunities as well as challenges. The capacity to handle substantial material quantities and rapidly produce prototypes, jigs, and final products of considerable dimensions necessitates the formulation of a well-suited production strategy. This involves setting production parameters to minimize material consumption and production time, considering the limitations of the utilized technologies, and ensuring the final product's quality. While slicers are commonly employed for establishing manufacturing strategies and production parameters, most additive manufacturing slicers are optimized for planar 3 axes 3D printing. This limitation hinders their ability to generate non-planar and freeform toolpaths. To overcome this constraint, this paper delves into the utilization of parametric modelling as a potent tool in the realm of non-planar additive manufacturing. It explores the possibilities offered by Rhinoceros Grasshopper software in designing toolpath strategies and fabricating non-planar layers. The paper addresses the associated challenges and limitations of parametric modelling, including computational complexity and the requirement for specialized software and expertise. It emphasizes the crucial need to strike a balance between design complexity and manufacturability to ensure the successful implementation of non-planar additive manufacturing processes.

A novel method for shaping innovative building forms, roofed with diversified complex continuous and discontinuous folded structures composed of many transformed corrugated shell units, is presented in the paper. The units are defined on the basis of specific reference polyhedral networks and arranged on arbitrary reference surfaces characterized by the negative Gaussian curvature. The method is presented using several computer models of complex building structures with folded plane-walled elevations. The proposed method significantly supplements the previous method developed for modelling building free forms, roofed with shell structures arranged in conformity with surfaces having the positive Gaussian curvature. Some basic rules using parameterization and governing the creation of the multi-plane elevations, ribbed continuous and discontinuous roof shell structures, arranged in different unconventional and visually attractive patterns, were developed. The elaborated specific sets of division coefficients are taken as parameters for the designed building structures. These sets determine unconventional polyhedral networks, which are composed of several specific sets that allow to define a polygonal eaves network, a reference surface and, finally, individual shell units of the roof structures. The developed method is presented using the example of three novel forms defined by means of the appropriately selected diversified sets of values of the division coefficients. The elaborated new forms confirm the innovative nature of the achieved results. By imposing appropriate proportions between the values of these division coefficients, the developed method enables the creation of two different groups continuous and discontinuous complex shell roof structures.

Controllable rotary fluid damper (CRFD) is an efficient and cheap energy dissipation device, which is used to reduce the impact of vibration in mechanical systems. In this paper, the CRFD controlled by a servo motor is developed to reduce the effects of vibrations in the helicopter flight control system. The dynamic mechanical characteristic of the CRFD is experimentally investigated by the MTS machine. Due to the complex factors such as high shear thinning rate and compressibility of the damping medium, inertia of moving parts and internal friction, the CRFD studied has highly nonlinear hysteresis characteristics. The accuracy of the damper modeling is of great significance for designing effective vibration reduction methods. Therefore, a new generalized viscous–nonlinear elastic model is proposed to track the mechanical characteristics of CRFD. On the basis of parameter sensitivity analysis, the proposed generalized viscous–nonlinear elastic model is modified. According to the identification results of the modified model, the main parameters are fitted as polynomial functions of motor rotation angle. Through error analysis between analytical torques and experimental torques, it is concluded that the modified generalized viscous–nonlinear elastic model has the smallest error compared with Kwok and Maxwell models, which indicates that the proposed modified model can accurately describe the mechanical characteristics of the CRFD under different working conditions.

In the article, a practical example of using the Autodesk Inventor Professional iLogic tool for designing self-propelled drilling rigs has been presented. Self-propelled drilling rigs are advanced mining machines with a complex structure. At the design stage, most of the structural changes affect the stability, manoeuvrability and coverage area of the machine. Working on detailed machine models is timeconsuming and unnecessary in the initial phase of the project. Therefore, a parametric 3D model of a two-boom drilling rig has been developed. It enables a quick analysis of selected machine properties depending on a number of significant parameters. The most important dimensions, masses and centres of gravity of each subassembly are entered by transparent editing windows. Next, model tests are carried out taking into account the pass through a face end of a given width as well as the coverage area of a face with specific dimensions. At each stage of model tests, the location of the machine's centre of gravity against the stability triangle background is analysed. In addition, the model allows entering the longitudinal and transverse angles of inclination of the working as well as determining the distance of the centre of gravity from the tipping edge. The model is a practical tool that makes it possible to easily determine the inner and outer turning radius as well as the working area of the machine while constantly controlling its stability. Due to the use of simplified geometry of subassemblies, the changes in parameters result in an instantaneous change of the model and allow a quick analysis of their impact.

The article concerns the computational model for analysing the stability of the BEV LHD loader. Works were carried out to develop an innovative, light battery-powered loader, which was the subject of an R&D project implemented in cooperation with Bumech S. A. Compared to the existing solutions of loaders with similar load capacity, this one is distinguished by the use of an individual electric drive in each wheel and a replaceable battery. A physical and mathematical model was developed taking into account the specificity of the BEV LHD loader. In the model, the masses of the battery, individual drives, the platform and excavated material are taken into account separately. The developed model allows determining the loader wheel pressure on the floor, depending on the location of its components’ centres of gravity, the turning angle of the machine, the amount of excavated material in the bucket and the position of the bucket. The input parameters also include the longitudinal and transverse excavation slope angles. In addition, the model enables determining the inner and outer turning radius of the loader. To verify the theoretical model, dynamic simulation tests were carried out. The results of simulation analyses confirmed the correctness of the developed theoretical model. The model was used to prepare a calculation sheet for analysing the stability on the basis of the adopted parameters. In the article, selected results of the conducted stability analyses have been presented, along with the proposed parameters ensuring the loader’s stability. The developed theoretical model enables a quick assessment of the loader’s stability, which, due to a number of innovative solutions, differs from existing designs. The structure of the loader at the design stage is subject to numerous modifications, which affect the distribution of the centres of gravity of individual components. The developed model of the loader is a useful, parameterized tool that allows assessing the stability and the values of the turning radii of the machine.

The process of design, development and production of cars has been strongly influenced by the use of computer technology since the 1980s. The philosophy of CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) approaches has become an integral part of the automotive industry. These technologies have shortened the innovation cycle in car model lines to 6-8 years. In the middle of this cycle, the so-called facelift of the model line is employed, when there are certain shape changes of the exterior and interior of the car or the equipment is expanded with new or improved elements. CAx systems enable changes to be made in such a short period of time. This article deals with the design of a fully parametric CAD model of a car interior element. Specifically, it is part of the door pull handle. The advantages of connecting a fully parametric model to a spreadsheet were pointed out. This link has a significant impact on the speed and flexibility of change processes on product models. The model was created in the Part Design volume modeler in the CAD system CATIA V5 Release21, which is used mainly in the automotive and aerospace industries. The parameters of the model were linked to the MS Excel spreadsheet.

The paper addresses the problem of the efficient shaping of curved steel rod structures conducted based on the Enneper surface. The proposed parametric design process consists in linking the geometric shaping of grid models with their structural analysis and optimization, which is realized through the application of design tools working in the Rhinoceros 3D software. The mechanical performance of lattices covered with glass panels is evaluated and the structures are pre-dimensioned. The presented aesthetic grid shells with good structural characteristics may constitute original coverings. However, the analysis, which targets an early stage of the design, aims at providing design guidelines to facilitate communication between architects and civil engineers.

BIM as a new way of designing and a new approach to creating building investment has already made itself at home in Europe and the first projects are already being implemented in Poland. The development of this technology and trends in the field of construction clearly show that sooner or later, to be able to play a part in the market, each office will have to go through a stage of change and adapt its work to BIM standards. Terrain projects or external networks, although often omitted in statements and publications related to parametric modeling, are also performed in BIM technology. Creating a smart network model opens up new possibilities and streamlines work on a given investment.

The aim of the study was to develop a practical approach to parametric shaping of spatial steel rod structures formed based on a hyperbolic paraboloid. This design approach was realized by application of designing tools working in environment of Rhinoceros 3D, that is its plug-in Grasshopper for geometric modelling and Karamba 3D for structural analysis. The goal of this research was to elaborate an universal scripts in order to create rod structures‘ models of various forms and grid patterns, as well as evaluating their structural behaviour dependently on various boundary conditions. The optimisation criterion was the minimum mass and deflection. Several proposals of coverings by means of single layer grid structures were presented and analysed to choose the best solution. The rod structures generated based on a hyperbolic paraboloid turned out to be structures with good static properties, so may be an interesting proposals to cover large areas.
