Objectives and competences

Students will: - know to solve some basic geometry construction tasks. - develop drawing and 3D skills. - use engineering projections. - know how to model and present solids on the 2D media. - use methods of computer graphics to present technical information including the use of CAD technology.

Content (Syllabus outline)

Introduction and terminology; the role of geometric modeling and descriptive geometry in the engineering. Presenting technical information and elements in technical drawing: Form and format, tipes of lines, dimension, hatching, fonts and media. Ergonomic of graphic communication. Geometric constructional problems (circle and tangent, transition curve, ellipse,…) Geometric transformations – 2D and 3D (translation, scaling, rotation). Projection methods. Classification. Perspective and parallel projections (including oblique, orthogonal and axonometric). Invariants and characteristics of projections. Free hand drawing. Projections - mathematical procedures. Projections - engineering standards. System of positioning of picture planes. 1st and 3rd angle view. Isometric, dimetric standard axonometry. Viewing. Computer graphics approach. 2D and 3D viewing, clipping, transformations. Computational methods in engineering (graphical data standards, compressing of data, vectorisation, rasterisations, basics of image processing) Modeling of solids. Analytical approach: methods of polygonal planes mesh. Control points and topology. Meshing. Parametrical patches. Synthetical approach. Methods of presenting of solids. Wire-frame model, solid model. Removing of hidden edges. Shading (sources of light, ambiental light, characteristics of materials – reflection coefficients, methods of textures, smoothing). Colors (physiology of perception, recommendations for use of colors in engineering and transportation praxis). Basics of modeling of curves (interpolation and approximation, control points, parametric curves, mathematical spline, physical spline, b-spline, Bezier etc.). Presenting technical information. Form and format. Fonts and media. Ergonomic of graphic communication. CAD tools. Tutorial seminar: Practical use of methods, techniques and technologies with general CAD tools, graphic input and output devices.
