Descriptive geometry and engineering graphics. How interesting to know

In all technical universities and technical schools there are subjects that are associated with drafting. Descriptive geometry and engineering graphics are the continuation of two school disciplines: drawing and geometry. All these sciences are interconnected indissolubly. But, nevertheless, everywhere its requirements, programs and methods of study.

Required Tools

Unfortunately, not all schools and technical schools have drafting. Students will find it more difficult to master engineering graphics, but if you want, you can catch up. Why did we speak about geometry above? It is necessary for the study of figures, for construction, analysis. How without geometry can you guess that the angle of the beam is 45 degrees? Or what is a right angle? Drawings on the engineering schedule do not do without the necessary tools. Often there are polygons, cones, spheres and other figures from geometry.

It is necessary to use the ruler and pencil, as well as the compass, protractor, square and officer's ruler, if necessary. Descriptive geometry and engineering graphics require you to have everything you need with you. It is recommended to take into account that the solid lines in the figures stand out with a pencil with a thick lead. Any student should not forget to take such a set of simple pencils with him, be sure to take the color ones, because in the descriptive geometry some complex tasks require different color lines. The eraser should be placed next to the pencils in advance, so as not to forget.

Descriptive geometry and uncomprehending students

On the first course in the first semester of technical specialty, all teachers and students are faced with trouble. For some reason, almost 90% of students from the stream can not understand this science. They think that there is some kind of strangeness: what and where does it take, how to build this line?

Many teachers try to demonstrate tasks not only on the board, but also for real. For example, take up the pyramid and ask the students to say how the points from the pyramid on the board will be projected. One word "projected" is already beginning to frighten listeners. In fact, everything is very simple. In simple words, you need to mark the corners of the pyramid on the board with dots and draw lines leading from the pyramid to the surface of the board. Descriptive geometry and engineering graphics are very different in terms of mastering by students. The second discipline is simpler.

How to help the student? It is necessary to advise him to represent objects. For example, let him take an opaque ruler and a square. The ruler will be in the left hand almost at the eyes, and the square on the desk. What does he see? Part of the body of the gon is invisible. So, on the drawing you should mark the invisible lines with a dotted line.

Engineering graphics and its features

Those who had a draft, almost nothing new to learn. Drawing details is much more interesting than figures and their projections to the surface. As a rule, in the second semester, unloved descriptive geometry is replaced by engineering and computer graphics. For students, there comes a relief.

Here you also need to be patient, and it's also important to have assiduity. Draw a good part and at the same time correctly place it is not so easy. And in order to correctly arrange the sizes, symbols, put a symbol in the drawing font, do everything according to GOST, you need to use directories and textbooks.

Engineering computer graphics - that's what attracts any student. It is much easier to make drawings in virtual space and print it on a plotter in a computer center than to do it, having a huge sheet of Whatman and a lot of free space.

It is very important for the successful passing of a test or examination to study not only the relevant literature, but also the programs. Which ones? "Compass", "AutoCad", "ArchiCAD" and others. It all depends on the profile of the university and the program.

Engineering graphics and revenue

Currently, the Internet can be found a lot of vacancies, where engineers with knowledge of "AutoCAD", "Compass" or "Archidik" are required. The work can be offered both in the office and remotely.

Therefore, those who want to receive a decent salary for projects, it is worthwhile seriously tackling the study of disciplines such as descriptive geometry and engineering graphics. With the second variant of earnings considered. With the first one can also earn by teaching students at home or in college.
