All technical universities and technical schools have subjects related to drawing. Descriptive geometry and engineering graphics are the successors of two school disciplines: drawing and geometry. All these sciences are inextricably linked. But, nevertheless, everywhere has its own requirements, programs and methods of study.
Required tools
Unfortunately, not all schools and technical schools have drawing. It will be more difficult for students to master engineering graphics, but if they wish, they can catch up. Why was it mentioned above about geometry? It is necessary when studying figures, for construction, analysis. How can you guess without geometry that the angle of the beam is 45 degrees? Or what is a right angle? Drawings on engineering graphics are not complete without the necessary tools. Often there are polygons, cones, spheres and other shapes from geometry.
You need the ability to use a ruler and a pencil, as well as compasses, a protractor, a square and an officer's rulerif 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 of the figures are highlighted with a pencil with a thick lead. Any student should not forget to take a set of simple pencils with him for such disciplines, be sure to take colored ones, because in descriptive geometry some complex tasks require different color selection of lines. The eraser should be put next to the pencils in advance so as not to forget.
Descriptive geometry and misunderstanding students
In the first year in the first semester of the technical speci alty, all teachers and students are faced with trouble. For some reason, almost 90% of the students from the stream cannot understand this science. It seems to them that some strange thing is happening: what and where does it come from, how was this line built?
Many teachers try to demonstrate problems not only on the board, but also for real. For example, they will pick up a pyramid and ask students to say how the points from the pyramid will be projected on the board. One word "projected" is already beginning to frighten listeners. In fact, everything is very simple. In simple terms, 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 easier.
How to help a student? He should be advised to present objects. For example, let's takeopaque ruler and 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 square's body became invisible. So, in the drawing, you need to mark the invisible lines with a dotted line.
Engineering graphics and its features
Those who have had drafting will learn practically nothing new. Drawing details is much more interesting than drawing figures and their projections on the surface. As a rule, in the second semester, the unloved descriptive geometry is replaced by engineering and computer graphics. The students are relieved.
Here you also need to be patient, and it is also important to have perseverance. It is not so easy to draw a detail correctly and at the same time correctly position it. And in order to correctly arrange the dimensions, designations, put down symbols in a drawing font, do everything in accordance with GOST, you need to use reference books and textbooks.
Engineering computer graphics - that's what attracts any student. It is much easier to make drawings in virtual space and print on a plotter in a computer center than to do it with a huge sheet of paper and a lot of free space.
It is very important to successfully pass a test or exam to study not only relevant literature, but also programs. What exactly? "Compass", "AutoCad", "ArchiCad" and others. It all depends on the profile of the university and the program.
Engineering graphics and income
Currently, there are many vacancies on the Internet that require engineers with knowledge"AutoCAD", "Compass" or "Archikada". Jobs can be offered both in the office and remotely.
Therefore, anyone who wants to get a decent salary for projects should seriously take up the study of such disciplines as descriptive geometry and engineering graphics. From the second option of earnings is considered. With the first, you can also earn money by teaching students at home or in college.
