Flange is a common part in engineering, and it is tedious to build the 3D models of flanges repeatedly. Nowadays 3D modeling softwares are widely used in many engineering fields such as mining machinery, transportation and petrochemical. In practical engineering, it is necessary to compute the reliability of a flange. For these reasons a reliability design system of flange was developed with VC and Protoolkit. In this system, we only need to input several parameters to build a flange model and to compute its reliability. Also it is easy to determine the key sizes of a flange with an appointed reliability. The application of the software shown that using the software can improve the work efficiency and decrease the labor intensity of designers.

The extruder is the key device to produce extrusion feed and food. Since different raw materialsi require different structural and technological parameters, the parametric design method must be used when an extruder is designed. The 3D (3-dimensional) software now available is just universal design platform, so the further development must be done based on universal software to realize the automatic design of machines for special purpose. In this paper the further development is carried out and the CAD (Computer Aided Design) system for the 3D parametric design of extruder is developed based on Solidworks. The system is developed with Visual C++, and it can be compatibly added in Solidworks as dynamic linkage library, which makes the modification of extruder more rapid and more correct. The paper introduces every function part in detail, including parameter input , design and calculation, 3D modeling of part, 3D modeling of assembly, engineering drawing. The realization of the automatic 3D modeling adopts the new idea of driven by dimension primarily and driven by program secondarily. The whole system is encapsulated in a menu of Solidworks. After some parameters, such as power and rotational speed, are imported through UI (User Interface), the system will automatically complete the design of extruder. Then 3D models and engineering drawings of parts or assembly can be exported according to the choice of user.

Abstract This paper gives an overview of a collaborative design system (CDS) for electromechanical products. To reduce design costs and to manufacture high-quality products, it is well known that concurrent engineering (CE) is a very efficient approach. Three-dimensional (3D) CAD system and engineering database system are essential components of CE. The CDS is an environment to realize CE. By creating 3D models in a computer and performing some simulations such as mechanical, electronic, software simulation and integrated simulations, it is possible to estimate functions, assemblability, manufacturability and so on, before making prototype models. In this paper, we outline the CDS and mainly discuss the total information management system (TIMS) which makes an important role of the CDS. This paper describes the implementation experience of some functions of the TIMS.

The practice of brokering is one of the concerns felt by the community at immigration services. The Directorate General of Immigration immediately followed up on the report, and appealed to all technical units of immigration to eradicate brokering practices and the practice of extortion (illegal levies) on immigration services. In line with this appeal, the Directorate General of Immigration made an online application called APAPO. Kantor Imigrasi Kelas II Non-TPI Kediri in follow-up to the practice of extortion and brokering also built the Flip Barrier Gate system. This system utilizes the use of RFID (Radio Frequent Identification) technology embedded in the access card. However, over time, this system began to find some problems. Among the obstacles that have arisen are the inactivity of this system because it is feared that it will become the center of the spread of COVID-19 due to the alternating use of access cards. In this research, development planning is carried out for the Flip Barrier Gate Class II Non-TPI Kediri Immigration Office. Flip Barrier Gate is integrated with APAPO through the use of QR code booking code as an access reader. In development planning, this study uses the system development theory described by Tata Sutabri. This phase consists of 5 stages, namely, system investigation, system analysis, system design, system implementation, system maintenance.

RGB-D sensors are novel sensing systems that capture RGB images along with pixel-wise depth information. Although they are widely used in various applications, RGB-D sensors have significant drawbacks with respect to 3D dense mapping of indoor environments. First, they only allow a measurement range with a limited distance (e.g., within 3 m) and a limited field of view. Second, the error of the depth measurement increases with increasing distance to the sensor. In this paper, we propose an enhanced RGB-D mapping method for detailed 3D modeling of large indoor environments by combining RGB image-based modeling and depth-based modeling. The scale ambiguity problem during the pose estimation with RGB image sequences can be resolved by integrating the information from the depth and visual information provided by the proposed system. A robust rigid-transformation recovery method is developed to register the RGB image-based and depth-based 3D models together. The proposed method is examined with two datasets collected in indoor environments for which the experimental results demonstrate the feasibility and robustness of the proposed method

In computer vision, 3D modeling refers to the process of developing 3D representation of the real world objects with systematic procedure. The 3D models can be built based on geometric information about the object or scene to be modeled using CAD/CAM software. However, this approach needs prior knowledge of the objects in the scene like dimension, size of objects, distance from the object to camera, et cetera. To make the 3D models more photo realistic and convenient, images of the objects can be used to build the 3D models. In this chapter, the authors propose a method to extract 3D model from single view perspective image. The approach is based on edge length and exploiting symmetric objects in the scene. Later, an application of touring into picture is discussed with the proposed method.

This chapter presents the implementation of a system that visualizes the construction process using 3D modeling data and schedule data to analyze construction planning. Previous papers have emphasized the benefits of visual 4D planning that combines 3D modeling data and process schedule data for work progress control. The proposed methodology offers rapid visualization of work performance with scheduled activity and facilitates construction planning and schedule inspection. Consequently, it should increase productivity and reduce rework. However, even major construction companies will not adopt such a work style, because the existing, well-organized way of working would not be readily changed unless the new style is proven to afford benefits that outweigh the effort and cost required to adapt to the style. The advanced CAD system, for example, is able to simulate the assembly process, and the advanced 3D graphic designer is able to animate the arrangement of objects. Even though each software provides multiple functionalities, the applications in practical use are all independent and specific, such as CAD for designing 3D models, and a project manager for scheduling and analyzing. Therefore, a system that integrates all outputs from each application is required to move from the conventional work style to the new one. This chapter, thus, aims to develop a system that integrates several types of data and enables the simulation of the construction progress by gradually showing 3D models according to the activity schedule. It is also possible to attach material data to each object and to display related information like cost and object properties. The system assumes the following requirements: (1) to import and display the 3D modeling data, (2) to import the project schedule, (3) to link each model and activity, (4) to give the material data on each object to enhance reality, and (5) to show cost accumulation. These functions are supposed to be realized such that the system utilizes the resources previously reserved. Therefore, the system should be able to import a DXF format file for 3D modeling data and access the MDB format database for the project schedule, including costs. The MDB file is originally a database that Microsoft Access creates. Microsoft Project, which is probably the most widely used software for project management, is also able to export the project data in this format. These functions are implemented with Microsoft Visual C++ and DirectX SDK. Although the system displays inaccurate models partially because of the misinterpretation of the DXF file, all of the demands listed above are satisfied currently. The authors of this chapter are now at the stage of implementation of further functions, that is, to display not only structures but also other elements such as the temporal space on the site, the route of delivery vehicles, and the work area of the temporally used heavy machinery, all for the sake of the visualization and analysis of the entire construction site.
