Two kinds of 3D modeling methods for square dome shaped pipe (SDSP) are presented in this paper, i.e. Manual modeling method by means of relative commands provided by AutoCAD and automatic modeling method by means of AutoLISP programming. The modeling steps are described in detail in the manual modeling method. Based on these, the 3D modeling application for SDSP is developed by means of AutoLISP language. The parameterized modeling of SDSP is achieved, and the drawing efficiency is increased effectively.

Cam mechanisms are widely used in automated machines. Globoid cam has received widespread attention for its eminent kinematics and dynamic performance in research and application. As a commonly used cam mechanism in industry, especially in the field of industrial robots, Globoid Cam has the advantages of being highly efficient, highly accurate and relatively cheap. This study used ProEngineer to create a 3D model of the Globoid Cam mechanism. This paper describes the steps used to create a 3D model of the Globoid Cam, and the basic principles behind the parametric 3D modeling method.

By analyzing the chart data and formulas in the traditional design of the roller chain, together with the SolidWorks modeling features, a fast modeling method of roller chain drive is presented on the basis of the main parameters in the chain drive design. In virtue of the Curve Driven Array, the chain modeling is executed in parts environment, with the track dimension property changed and the dimension driven mathematical formula established to correct the error between theoretical calculation and practical graphics, which ensures a successful array and provides an effective way for the rapid 3D model establishment of chains and the chain drive assembly.

The exploration of oil and gas, especially in Indonesia is experiencing various challenges and varying degrees of difficulty. In this research, the researcher tries to make a 3D modeling from gravity data, where the model will show a structure to determine the central coordinates for drilling. Pertamina has carried out drilling at a location in NTT and it turns out that the well does not produce oil and gas, even though the log data reads an oil showing that the area should have the prospect of producing oil, but the wells that have been drilled do not show any oil or gas, therefore the researchers tried to make a 3D model determine the structure around the production well. In this research, it was seen that the area of the previous drilling point had deviated from the top of the up dome and it was also seen in this structure that the area was deviated by about 3 kilometers and depth must exceed 526 m, the researcher concluded that the drilling point must be at X, Y coordinates.

Currently, for tunnels, the design centerline and design cross-section with time stamps are used for dynamic three-dimensional (3D) modeling. However, this approach cannot correctly reflect some qualities of tunneling or some special cases, such as landslips. Therefore, a dynamic 3D model of a tunnel based on spatiotemporal data from survey cross-sections is proposed in this paper. This model can not only playback the excavation process but also reflect qualities of a project typically missed. In this paper, a new conceptual model for dynamic 3D modeling of tunneling survey data is introduced. Some specific solutions are proposed using key corresponding technologies for coordinate transformation of cross-sections from linear engineering coordinates to global projection coordinates, data structure of files and database, and dynamic 3D modeling. A 3D tunnel TIN model was proposed using the optimized minimum direction angle algorithm. The last section implements the construction of a survey data collection, acquisition, and dynamic simulation system, which verifies the feasibility and practicality of this modeling method.

The clinical experience demonstrates the importance of 3D modeling when planning surgical intervention in patients with pulmonary tuberculosis. The 3D model was built up based computed tomography data using Avtoplan software with plug-ins for segmentation of the lung, pathological foci, vascular structures, and bronchial tree. The data obtained during 3D modeling allowed us to plan surgery and the data were fully confirmed during the operation. The 3D model with color mapping reveals syntopy, which is extremely difficult to determine using standard computed tomography and allows the wider use of minimally invasive endoscopic surgical interventions.

Abstract Objectives This systematic review evaluated whether CBCT is a better diagnostic tool in facial forensic reconstruction. Forensic facial reconstruction is a technique to reconstruct human face from unidentified face from skull remains for human identification and facial recognition. Materials and methods Article selection and data extraction was done based on the inclusion and exclusion criteria devised for the study. The articles were screened from PubMed, ProQuest, Google scholar, Science direct and Scopus. Result Three hundred and thirty-nine articles were initially identified from which seven articles were full text reviewed and included in the review. All the articles included in this study suggest that the facial reconstruction done using CBCT are reliable. Conclusion The computerized 3D modeling method produces reliable facial reconstructions which involves the images scanned from CBCT and the combination method. The computerized 3D modeling method produces facial reconstruction which almost mimics the original resemblance.
