Subject 'CAD Systems'Name in Estonian: CAD-projekteerimine
General descriptionProjection environments, sheet formats. Menues, commands and accomlishment of drawings in 2-D environment. Shifting, rotation, reflection, scaling of objects. Accomplishment of models with 3-D tools: the bodies with protrusions, indents and undercuts of various shape, the details with threads and ribs. Accomplishment of working drawings of 3-D models (elevations, sections, local sections, local elevations, dimensioning of drawings, surface roughnesses). Accomplishment of models in sheetmetal treatment environment (bending, tensile and flanged details).Developments. Accomplishment of simple assembly in assembly environment, correlations. Execution of technical drawings. Terminal requirement is the proficiency of accomplishment of technical drawings both with 2-D (Draft) and 3-D modelling tools.
General aimThe aim of the course is providing primary knowledge to accomplish technical drawings of machine building with Solid Edge tools.
AimStudent having passed the course: is able to execute technical drawings on computer with Solid Edge tools, and knows how to print out drawings; is able to accomplish working drawings of details in 2-D (Draft); is able to make models of various machine building details with 3-D modelling tool (including making the detail models from sheetmetal in sheetmetal treatment environment), to process them and to make working drawings of 3-D models; is able to accomplish 3-D models of various easier assemblies with creating necessary interrelationships between details in assembly environment, and to make their assembly drawings in projection environment.

2. There are prerequirements to get the final mark: 1. Five homeworks must be submitted by portfolio and rated positively (1…5). 2. Classroom written tests must be passed positvely (1...5). The homework that has got the mark 0 must be amended and resubmitted until getting a positive mark (1... 5). Unsuccessful tests can be repeated. EVALUATION CRITERION "1" -kadet is able to to model the easiest parts of the 3D models, and generate from them drawings. Requires a non-significant teacher aid. The choice of images is irrational, there are no sections. Some dimensions and axes, ara missing. There are the solution of task is incomplete and there are some errors, framing an unfinished drawing, implementation of the standards and knowledge are poor. "2" -kadet is able to to model the easiest parts of the 3D models, and generate from them drawings. There are unnecessary images, sections are badly done. Some dimensions and axes, ara missing. There are incorrect solution to the task and a number of inaccuracies in mechanical engineering standards are used, the drawings are experiencing some inaccuracies "3" -kadet is able to to model the average complexity of 3D details and generate drawings from them. Images and sections are correctlyselected. There are no few axes, there are unnecessary dimensions. Mechanical engineering standards are acquired, the solutions accuracy is not sufficient , there are deviations from the requirements of the format of Figure "4" -kadet is able to to model the average complexity of 3D details and generate drawings from them. Images and sections are correctly selected. Dimensions is rationally, there may be no single dimension or axis the task of the solution corresponds to clearance of small deficiencies to the requirements of the mechanical engineering standards "5" -kadet is able to to model the average complexity of 3D details and generate drawings from them. Images and sections are correctly selected. Dimensioned is rationally there are logical solutions of the problems, and formatted in accordance with ISO standards, there are no mistakes in the works. The work is correct. Drawing is a professionally formalized. Final grade formation: Prelim (graded) quiz in auditory in line with evaluation criterion. The homeworks portfolio mark can raise or lower the final grade by one unit.
