Due to the rapid development of technology, the use of numerically controlled machines in the industry is increasing. The main idea behind this paper is computer-aided design (CAD) based low-cost computer numerical control 2D drawing robot that can accurately draw complex circuits, diagrams, logos, etc. The system is created using open-source hardware and software, which makes it available at a low cost. The open-source LibreCAD application has been used for computer-aided design. Geometric data of a CAD model is converted to coordinate points using the python-based F-Engrave application. This system uses the Arduino UNO board as a signal generator of the universal g-code sender without compromising the performance. The proposed drawing robot is designed as a low-cost robot for educational purposes and aims to increase the student's interest in robotics and computer-aided design (CAD) skills to the next level. The drawing robot structure has been developed, and it meets the requirements of low cost with satisfactory experimental results.

Personnel training of higher vocational industrial design for engineering class will be positioned on designing both the product exterior appearance and the interior structure. Moreover, with the method of computer-aided design and modeling, product design process from design ideas to the real product was completed for training highly skilled application-oriented talents. The designing idea of personnel training scheme is first to identify positions and tasks set by the positions, then to study the required knowledge set by the tasks, and ultimately to make specific teaching content scheme. Curriculum planning adopted the enterprise project mode could realize zero distance links with enterprise.

This paper presents a new concept and method to design mechanisms’ stability using over-constraint. The designs involve the use of parametric Computer-Aided Design (CAD) software to synthesize a mechanism’s geometry in order to achieve a design’s specific bistability requirements. This method ensures a stable position without the need of a hard-stop. There are two main initial design considerations that need to be met in this analysis. First, both (first and second) state of the mechanism should be chosen and should represent the mechanism’s desired stable positions. The first state is the position that the mechanism was manufactured or assembled at, whereas the second state is the position at which the mechanism is toggled to. The second consideration is the assumption that the magnitude of the joints’ torsional spring stiffness is small i.e. living hinges. The main idea is to attach a Potential Energy Element (PEE), such as a spring or a compliant link, to the four-bar mechanism such that it is unstretched in both stable positions and has to deform (stretch or compress) during the motion between stable states. This approach seems to allow the designer considerable freedom in amount of motion between stable states and in the amount of force required to toggle between stable states.

With the advent of technology, architecture has also benefitted by applying tools and equipment instead of conventional manual works. Computational technology has come to the aid of the design process. There is a shift from hand drawing to computer-aided design. Drawing had become more of a tool to explore design ideas and express proposed solutions. The coordination between hand and mind will remain superior until those tools progress. The physical human conditional gesture continues with reliability and is still relevant in idea generation and presentations. But in recent years, technology has driven architectural computing into a new exploratory domain. This research aims on building a procedural 3D model using a pixel-based tracing of the sketch of an architectural plan. The proposed method blurs the line between hand sketching and CAD, thus providing a quicker solution in visualizing the design. The point generated by vectorizing the bitmap data is used to achieve the desired curve. It is all done in a fully parametric model where the user has control over the properties for modeling. Finally, we validate our result with a study in which we compare the conventional modeling tools and establish a system to build the 3D model from an architectural plan. This study helps in believing that CAD and hand drawing could perfectly coexist and finding the right balance in architectural design.

Green infrastructure has been used for environmental conservation and management with many similar concepts such as green-space network, green-link network, and green-ways network based on the objectives of the cities for greening. Seoul established the 2030 Seoul City Master Plan that contains green-link network projects to connect critical green areas within the city. However, the plan does not have detailed analysis for the green infrastructure to incorporate land-cover information to many structural classes. This study maps green infrastructure networks of Seoul for complementing their green plans with identifying and ranking green areas. Hubs and links that are the main elements of green infrastructure have been identified through incorporating cadastral data of 967,502 parcels to 135 of land use maps using Geographic Information System. The study extracted 1,365 of green areas that represent an area of 24,530 ha within the city and buffered these areas to identify districts as critical green areas that have hubs and links. At a city scale, the study used 103,553 of parcel data for ranking extracted 20 districts, and 17,860 of parcel data for ranking extracted 42 links connecting the districts. At a district scale, this study used 87,826 of parcel data for analyzing the status of potential links within the districts and ranking these districts for green infrastructure. This assessment analyzes the main elements of green infrastructure and suggests site prioritization for green infrastructure under variable scenarios of green and developed areas in a metropolitan city.

Designing and manufacturing work on Material Handling Equipments specially material conveying system is being carried out in many heavy engineering companies. To overcome the time delay, in conventional design approach, for the design of belt conveyors by utilizing the CAD facilities is not only the need of time but is also necessary for the market competition in this area. This paper explains the methodology of converting the conventional design process of belt conveyors to Computer Aided Design (CAD). This includes software engineering approach and the usage of different tools in order to get a computer based solution for the design of belt conveyors. Application of parametric design and design for manufacturing concepts could also be followed. The main idea is to automate the drafting process and the lengthy calculations involved in the design phase. General arrangement or assembly of a belt conveyor is shown in Fig. 1.

We propose an improved micro reactor design for a scalable microfluidic device, in which enzymes are immobilized in a hydrogel matrix. Furthermore, fluid flow is controlled by means of hydrogel-based micro-valves. In this work, computational flow simulations will be compared to experimental results to highlight new design ideas and to improve wetting and concentration distribution through the entire chamber volume, even for high aspect ratios. Additionally, modelling concepts will be introduced to efficiently describe multi-domain problems like enzyme reactions. With the help of a computer-aided design process which is capable to simulate hydrogel-based microfluidic systems it is possible to better understand, predict and visualize the behavior of micro-reactors and support the development of highly integrated hydrogel-based microfluidic circuits.

The goal of the study is to determine the actual areas and the geographical distri- bution of Urban Green Spaces (UGS) in Kyiv; compile and analyse the ratings of the city administrative districts by key UGS indicators and substantiate the level of comfortable living in each district according to the concept of a green compact city. The goal stems from the announcement of an official strategy of transforming Kyiv into a comfortable compact city with an attractive green infrastructure. To achieve this goal, we have calculated a number of major indicators of the modern green infrastructure of Kyiv in all ten city districts. According to the method we developed, we analysed the drawings of the urban development master plan and regulatory documents, and conducted a field survey of significant UGS sites in Kyiv. The data obtained were used to make a UGS map of Kyiv and other thematic maps. For the most accurate calculation of key UGS indicators, we processed several thousand contours in Kyiv’s cartographic base. The sizes of Urban Protected Areas (UPA) were found separately, and their share in the total city territory and of each district (Conservation Coefficients) was determined. In so doing, UPA distribution was found to be very irregular, with a total area of 174.9 km2, or about 21.2% of that of Ukraine’s capital. We analysed the ratio of the city population and the areas of green spaces in each Kyiv district. To identify districts with a different UGS coverage, we calculated the Greenness Coefficients (GC) and compiled a rating of Kyiv districts by their level of greenness, using the Greenness Coefficients Index. Significant GC variations in different city districts were substantiated. In contrast to previous studies, we calculated the provision of Kyiv residents with green zones of not merely common usage, but also with those of all other kinds, including UPA. We also calculated the Green space provision per person and compiled ratings of Kyiv districts by the Green Space Provision Index. The results were presented on a relevant map. Based on calculating the share of protected areas in the total UGS area, we found the ratings of Kyiv districts by the Green space legally protected Index. Wherein, we found significant variations among the districts by the ratio of protected areas and green spaces deprived of any legal protection. This increases their vulnerability to projected development attempts. We calculated the Integral Green Space Index (GSI) based on processing all significant UGS indicators of Kyiv. GSI allows for an integral assessment of the condition of the Urban Green Infrastructure (UGI) in Kyiv, and it is the key criterion of its compliance with modern requirements to an ideal compact city. Holosiivskyi District received the highest GSI rating. It is uniformly replete with UGS, which are provided for quality recreation and, at the same time, are protected by environmental legislation. Solomianskyi District received the lowest rating, and almost all the elements of its existing UGI require a cardinal optimisation. As a whole, the indicators we calculated can create an illusion of adequate provision of Kyiv with UGS. Actually, they are distributed very irregularly in the majority of districts. The results of our study are indicative of the presence of many challenging locations that require an extension of existing UGS and the development of new ones pursuant to the principles of compact city planning. Since UGI planning depends on the implementation of the Urban Development Master Plan, it makes sense to include the Green Space Index to the key indicators of the Kyiv Development Strategy. The draft new City General Plan should also be refined with account of the above-mentioned problems.

As Computer-Aided Design software has become more advanced, the use of hand-drawn engineering drawings has greatly diminished. This reduction has led to free-hand sketching becoming less emphasized in engineering education. While many engineering curriculums formerly included courses dedicated entirely to sketching and hand drafting, these topics are no longer addressed by most current curriculums. However, it has been observed that sketching has many benefits including improved communication in the design process, idea generation exercises, and visualizing design ideas in three-dimensional space. While isometric sketching has long been the preferred method in engineering curriculums, there are benefits of teaching perspective sketching including the creation of more realistic sketches for communication and idea generation. This paper presents the development of a perspective-based sketching curriculum and the study of how this method compares to more traditional methods of teaching sketching to students in a freshman level engineering graphics course. The results show that the perspective-based sketching method leads to equivalent gains in spatial visualization skills and final design self-efficacy as the traditional method of teaching hand sketching. While maintaining these skills, the new method also taught students additional skills. Through surveys and interviews, the students expressed that these skills would be useful to them in their future coursework and careers.
