The effects of computer-aided design software on engineering students’ spatial visualisation skills

The paper presents a method developed and used by the CCHAPT researchers for the graphic plotting of the index tests results for hydraulic turbines, the comparison of the efficiency curves resulted from testing to those obtained by the model transposition [1] i.e. the determination and comparison of the existing combinatory cam with that obtained from tests.The method presented in the paper was born from the need for processing and presenting the results of index tests within the shortest delay and eliminating the errors that might occur in the results plotting.

This article discusses that how mechanical engineers will pair their already-familiar computer-aided design software with not-so-familiar three-dimensional (3D) displays for true 3D design. This is in accordance to a number of vendors' intent on supplying the newfangled computer monitors, within the next two decades. Although some of the devices are already on the market, affordable 3D monitors and displays seem to be more than a decade away, according to one university professor at work on such a project. Widespread adoption is still hindered by factors such as cost, software availability, and lack of a mouse-like device needed to interact with what’s on screen. Over the past 25 years, mechanical engineers have witnessed evolutionary change in design methods-from pen and paper to two-dimensional software and now to 3-D computer-aided design. While software makers have stepped up with sleeker and faster modeling capabilities, visualization lags. Computer users two decades out will carry out all business, web surfing, and gaming on 3-D displays. That next generation may well find the very idea of 2-D monitors to be as dated as record albums seem to teenagers today.

This article compared the accuracy of producing patient-specific cranioplasty implants using four different approaches. Benchmark geometry was designed to represent a cranium and a defect added simulating a craniectomy. An ‘ideal’ contour reconstruction was calculated and compared against reconstructions resulting from the four approaches –‘conventional’, ‘semi-digital’, ‘digital – non-automated’ and ‘digital – semi-automated’. The ‘conventional’ approach relied on hand carving a reconstruction, turning this into a press tool, and pressing titanium sheet. This approach is common in the UK National Health Service. The ‘semi-digital’ approach removed the hand-carving element. Both of the ‘digital’ approaches utilised additive manufacturing to produce the end-use implant. The geometries were designed using a non-specialised computer-aided design software and a semi-automated cranioplasty implant-specific computer-aided design software. It was found that all plates were clinically acceptable and that the digitally designed and additive manufacturing plates were as accurate as the conventional implants. There were no significant differences between the additive manufacturing plates designed using non-specialised computer-aided design software and those designed using the semi-automated tool. The semi-automated software and additive manufacturing production process were capable of producing cranioplasty implants of similar accuracy to multi-purpose software and additive manufacturing, and both were more accurate than handmade implants. The difference was not of clinical significance, demonstrating that the accuracy of additive manufacturing cranioplasty implants meets current best practice.

AbstractBackgroundIdentification of sex from skeletal remains is an essential step in forensic anthropology. The skull is the second choice, after the pelvis, to estimate sex by osteometric methods.ObjectiveTo evaluate the process of identification of sex in Northern Thai from crania by using computer-aided design (AutoCAD) software and conventional caliper methods.MethodsDry skulls of 86 men and 74 women were examined. AutoCAD software and digital calipers were used to measure dimensions. Eleven of the 15 parameters were created for this study.ResultsMen are significantly larger than women in all parameters, except in the nasospinale–prosthion measurement. There were no significant differences in the intraobserver error test and between the AutoCAD and digital caliper measurements. The logistic regression analysis yielded a sex classification accuracy rate of 92.9% in men, 93.4% in women, and 93.1% of overall accuracy for AutoCAD software. When using digital calipers, there was an accuracy rate of 89.3% in men, 94.7% in women, and 91.9% for overall accuracy.ConclusionsAutoCAD software is a reliable method to predict the sex and provide high accuracy in sex determination from crania.

ABSTRACTThe upper structure is the parts that make up buildings such as sloof, walls, columns, beams, and roofs. In this upper structure these components have a very important role. Today, civil engineering students are required to be able to plan well so that they are strong and durable for a long time.In planning this upper structure, of course there are many methods that can be used to calculate moments, one of them is ultimate moment method, which can be combined with a reference from SK SNI 2847,2013. For pouring images can be presented with CAD (Computer Aided Design) software called AutoCAD.The results of this plan are used for roof and floor plates used 100 mm and 120 mm thick with reinforcement used 12 mm main reinforcement and 8 mm stirrup reinforcement with a distance of 200 mm. For beams and Sloof used the same, which is 16 mm for basic reinforcement and 10 mm for reinforcement Sengkang with a distance of 200 mm. Whereas for columns, reinforcement 16 mm and Sengkang 12 mm with a distance of 200 mm are used. The load distribution that occurs is for the roof floor of 20.640,924 kgm, because the assumption of loading the 1st floor to 6th is the same, which is equal to 23.233,644 kgm. The moments that occur in this plan are on the plate occurred at 17.074,370 kgm, the beam occurred at 342.733,875 kgm and 493.536,780 kgm. In the column arises a fairly large moment, with a value of 551.697,600 kgm. From the calculation of the earthquake load get the result = 159843 (kNm).Keywords: Planning, Structure, CAD, SNI
