In the projects for making 3D illustrations a client regularly loses judgment as to which system to use amid the procedure. It is likewise a noteworthy issue in showing representation, in light of the fact that the last result can be acquired by different strategies utilizing instruments accessible as a part of the projects. This paper introduces and examines the cases of the use of PC perception in showing specialized subjects on science resources. For this reason CAD projects, for example, Inventor and AutoCAD were utilized. The commercial vantages of 3D more than 2D outline were depicted and the investigation and assessment of the accessible devices for 3D demonstrating and PC representation were directed. In the last some portion of the work chose illustrations of PC perception are exhibited, in the setting of supporting showing the understudies of science fields of studies. Keywords: computer visualization, computer modelling, teaching. INTRODUCTION The educating of specialized subjects, for example, building, representation or machine outline rudiments of specialized fields, up to this point, was taught through the utilization of customary techniques for figuring and drawing. These days, the advancement of PCs and programming permits you to utilize them to support the work of the cutting edge engineer. At first, it was to finished the conventional strategies by reputting a planning phase and mini-computer. In any case, now, the utilization of PCs with particular programming, replaces totally the customary techniques. PC projects are utilized, entomb alia, on the phases of item plan, building estimations and assembling of gadgets. Progressively, amid these procedures the PC perception is utilized. PC perception is the regular name for graphical routines to make, examine and convey data. It is most usually utilized as a part of common modern areas, for example, the development business, machine, vitality, and so forth,. be that as it may, likewise in medication, promoting, photography and numerous different regions of life. Representation additionally influences the routines leading exploration, furthermore fills instructive needs [1]. During the time spent instructing, the utilization of 3D demonstrating and PC representation makes new open doors for learning exchange. It makes specialized issues introduced on normally specialized subjects, less demanding to comprehend translate and set up the documentation. As an ex-abundant, amid building assembling classes, an understudy can outline an item, utilizing displaying and representation, make a PC model, pre-pare its documentation, and afterward deliver it. It is additionally significant that by performing work with projects that utilization PC representation and 3D displaying, individuals add to its specialized and spatial creative ability, which is of incredible significance in the preliminary procedure of the item.

2 These days, there are numerous projects for 3D demonstrating and PC representation on the market. Different application projects can be distinguished here, for example, 3 ds Max, Blender or Maya 3D. In designing applications, and in addition science training projects from the gathering of CAD/CAM/CAE are prevalently utilized. They are among the projects which are a piece of CIM (Computer Integrated Manufacturing). They are utilized regularly to help building in the configuration and assembling of an item. Under the term CAD/CAM/CAE we comprehend Computer Aided Design, Computer Aided Manufacturing and Computer Aided Engineering. These are the primary instruments utilized by cutting edge engineers, paying little respect to their industry. Subsequently, it is a fundamental element of the training of future designers, examining specialized fields Computer Aided Design (CAD) involves the use of programs and computer equipment during engineering design. Characteristic of CAD is creating digital geometric models that determine the structural form of the product (one or more objects). Computer-aided design software is meant to support the work of the engineer mostly in the early stages of product development. CAD programs are not only applicable when creating and modifying 2D construction documentation, but especially in 3D modelling, performing assembly, presentation and analysis of endurance where computer visualization is applicable (Figure 1abc). CAD software can be used for documentation of the treatment process used in the conventional machines, and for the preparation of 2D/3D models used in CAM programs. PC supported assembling (CAM) is the joining of the outline and assembling stages. CAM programming encourages planning technological forms. A trademark highlight of PC programming, which encourages the preparation handling of the models which emerge in PC demonstrating 2D/3D into machine control guidelines in CNC machine apparatuses, which allow preparing the components [2]. PC visualization is utilized here, for instance in checking whether there are no impacts of a device with the workpiece or any piece of the machine, amid the machining etc. Computer Aided Engineering (CAE) is the use of computer programs to simulate the functioning of the product. This is to improve projects and support processes of resolving design errors [4]. The Examples of CAD programs are AutoCAD and Inventor. AutoCAD is a commercial program created and distributed by Autodesk. It is used for computer-aided design in 2D and 3D. Originally, it was used mainly by technicians. Currently it is used by architects, electricians and other designers due to the fact that Autodesk has expanded the program with many specialized overlays such as AutoCAD Electrical, AutoCAD Mechanical, Mechanical Desktop, Architectural Desktop, Civil Design, etc. Since 2005 version, the program has become a good tool for creating 3D models, with which you can create photorealistic visualizations. With AutoCAD, the most commonly created is 2D documentation, and then, based on it, 3D models and their visualization are made [4 6]. Autodesk Inventor is another business Autodesk program. It is a parametric framework which permits outlining items in 3D space, with a plausibility to make 2D and 3D documentation. Amid the work various leveled models are created as successive trees of a past filled with operations performed by the client. Creator likewise empowers the making of congregations in light of 3D models and performing their presentation [7 9]. Autodesk Inventor HSM Express 2014 is a free CAM solution for PC supported assembling, which is incorporated with Autodesk Inventor plan environment. It Includes systems of creating apparatus ways for processing, penetrating, digging and boring. In the wake of producing device ways, the consequences of simulation can be checked utilizing the player. In conclusion, we can say that CAD / CAM / CAE are good tools supporting the work of modern engineers, as well as facilitating the conduct of the process of teaching technical subjects. Anshu Page 9

3 AN EXAMPLE OF THE USE OF COMPUTER VISUALIZATION IN INVENTOR IN SCIENCE EDUCATION In programs CAD / CAM / CAE user often loses recognition, which of the techniques to use during the work. It is also a major problem in the teaching process, because the final result can be obtained by various methods. Choosing the right tools and modelling techniques is often debatable. In today s computer programs we have a lot of computer techniques used for Fig. 1. The use of visualization in Inventor: a) 3D model, b) submission, c) strength analysis, d) tooling of CAM modelling and visualization of 3D objects. Modelling of three-dimensional parts usually starts with a two-dimensional 2D sketch that defines their shape. A good example includes the tools for sketching in Inventor. When you create a sketch in Inventor, information about relations is registered Anshu Page 10

4 additionally. Due to relations (bonding), the process of editing the sketch is easier, as long as they are properly applied. The Sketch is launched on the sketch plane, on which episodes, arcs, circles, etc. are plotted. The generated sketch becomes a profile which is used as the basis for the operation of creation of a 3D object The basic techniques to create 3D objects in Inventor, among others are: Extrude, Rotate, Loft and Drag. Necessary for the modelling of very complex objects are auxiliary construction elements, such as: surface, axis, or point coordinate system. The Planes are primarily used as a space for sketching when there is no plane of a part suitable for creating two-dimensional sketches of elements. On the basis of the 3D model it is possible to perform 2D documentation. Figure 2 shows a visualization of the 3D model and 2D documentation made on its basis. This is an example, implemented in the classroom, by the students in the field of computer engineering graphics. a) Anshu Page 11
