Foundation is very important, step by step, learning to use, practice makes perfect.
Foundation is very important
Practice has proved that the "manual drawing board" drawing ability is the foundation of the computer drawing ability to learn "AutoCAD", the need for a certain amount of knowledge and ability to draw geometric geometry, the need for certain Learning AutoCAD requires certain knowledge and ability to draw geometry, requires a certain degree of literacy, especially geometric drawing ability, in general, the level of manual drawing high people, easier to learn, the effect is better.
Second, step by step
The whole learning process should be in a step by step manner, the first to understand the basic knowledge of computer graphics, such as the relative right angle coordinates and relative polar coordinates, so that they can be from the shallow to the deep, from the simple to the complex to master the use of AutoCAD technology.
Three, learning to use
In the study of AutoCAD commands should always be combined with the practical application, do not spend the main energy in the various commands to learn in isolation; the principle of learning to use throughout the entire learning process, so that they have a deep understanding of the drawing commands and image, and is conducive to the development of their own application of AutoCAD to complete the drawing independently. AutoCAD independently complete the ability to draw.
Four, practice makes perfect
To force themselves to do a few comprehensive examples, detailed graphics drawing, so that they can grasp the entire drawing process from a global perspective.

. p>Tips:
1, the same drawing a map, some people draw the size of the moderate, some people draw the graphic is very small, or even invisible, this is because the drawing area boundaries of the setting operation is not done, or although the LIMITS command is set, but forgot to use the ALL option in the ZOOM command to re-drawing area to be regularized. The drawing area is set according to the actual drawing needs.
2, some people use the line name "HIDDEN" line drawing, but found that the line looks like a solid line, which is "line ratio" is not appropriate to cause, that is to say, "line ratio" is too large, and may also be "line ratio" is too large. Proportion" is too large, or it may be too small, the solution is to open the Line Manager dialog box, modify its "Global Proportion Factor" to the appropriate value.
