With the rapid development of computer application technology, computer-aided design has become an important part of modern industrial design. AutoCAD software has the characteristics of simple operation and powerful functions. It has been widely used in mechanical design, architectural design, electronics and other graphic design fields. So how can we learn AutoCAD drawing well? Here are some suggestions.

Share the following cad tutorials

Cad course 1. When learning AutoCAD, we must master the correct methods.

1. Some beginners do not perform well in learning AutoCAD, often because their interest in learning is not high, which leads to low learning efficiency. Interest is the best teacher. Beginners learning AutoCAD should regard the process of learning and operation as learning a new electronic game.

2. The whole learning process should adopt a step-by-step approach. To learn and master AutoCAD well, we must first know how to draw by hand, and be very clear about the geometric knowledge of drawing methods used in the drawing process. Only in this way can we further consider how to use AutoCAD and how to do it. Practice has proved that AutoCAD drawing and geometric drawing are strong, easy to learn and effective. Then learn the basic knowledge of computer drawing such as relative rectangular coordinates and relative polar coordinates, so that you can master the use technology of AutoCAD from simple to complex.

3. One advantage of studying cad course is that you can draw accurately. Accurate drawing means accurate size and drawing in place. Parallel lines must be parallel; The vertices of the angle formed by two lines must coincide. When the dimension is not drawn according to the standard, it is necessary to modify the data when marking the dimension, which not only affects the beauty of the drawing, but also directly affects the authenticity of the drawing. Therefore, in the process of painting, we must be careful, step by step and accurate.

The purpose of computer drawing is to improve the drawing speed and efficiency, and the fastest operation method is to use shortcut keys. Therefore, when drawing graphics with AutoCAD, you should try to remember and use shortcut keys, and both hands can work, so as to improve the speed of drawing graphics. When you want to execute a command in a graphic, you can directly enter the shortcut key of the command with your left hand, and then click the right mouse button with your right hand, which is the same as clicking the command icon with your left mouse button.

For example, to execute the move command, you can enter quotM quot with your left hand and then click the right mouse button with your right hand to execute the move command. Common command shortQuots, such as offset QuotO Quot, fill quotquot, quot Quotr Quot, expand quotquot, write blockquot, abandon quotquot, translate quotquot, and create arc quotquot and straight line quotquot in real time. Common key points are: capture F3, orthogonal F8, polar coordinate F 10, object tracking F 1 1. A simple suggestion for beginners. In the early days of learning AutoCAD, I tried to draw my own practice graphics by using shortcut commands.

5. When learning AutoCAD commands, we must combine the actual application, and don't spend the main energy on learning each command in isolation; We should put the principle of applying what we have learned into the whole learning process, so that we can have a profound and vivid understanding of drawing commands, which is conducive to cultivating our ability to complete drawing independently with AutoCAD. You have to force yourself to do a few comprehensive examples and draw pictures in detail, so that you can master the whole drawing process from the overall point of view and put yourself into practical work after learning AutoCAD.

Cad course 2. Skills of using AutoCAD to improve drawing efficiency

1. follows certain drawing principles.

Drawing steps: Set the unit of sheet setting and precision setting, and set several layers to set the object style to start drawing.

Drawing always uses the ratio of 1: 1. To change the size of the pattern, you can set different printing scales in the paper space when printing.

Set different layers, colors and line widths for different types of primitive objects, and the color, line type and line width of primitive pairs should be controlled according to the layers.

When drawing accurately, you can use the raster capture function and set the raster capture interval to an appropriate value.

Don't draw picture frames and graphics in the same picture. Insert a picture frame in the layout, and then print the picture.

For famous objects, such as views, layers, blocks, linetypes, text styles, print styles, etc. Naming should not only be concise, but also follow certain rules to make it easy to find and use.

Set some common settings, such as layer, label style, text style, grid capture, etc. In the graphic template file. When drawing a new drawing in the future, you can click Create New Drawing with Template in the wizard to open it and start drawing.

2. Choose the appropriate command.

In the specific operation of AutoCAD, although there are many formulas that can achieve the same goal, if the command is selected properly, the operation steps will be significantly reduced and the drawing efficiency will be improved. This is just a typical case.

Generate a line or segment

In Beginners' Introduction to cad Drawing, commands such as LINE, XLINE, RAY, PLINE and MLINE can all be used to generate straight LINEs or line segments, but only the line command is the most commonly used and flexible.

In order to ensure that the three views of an object correspond, that is, quot, long alignment, equal width, high quot,, XLINE and RAY commands should draw several auxiliary lines, and then trim the redundant parts.

To quickly generate a closed filled boundary or construction area, you should use the PLINE command. You can use the PEDIT command to edit line segments generated by PLINE.

When multiple parallel line segments are generated at one time, and each line segment may use different colors and linetypes, you can choose the MLINE command.

The above cad tutorials are some suggestions for beginners of cad drawing. However, the key to learning AutoCAD software is to practice more, summarize more and read more books on the computer. As the saying goes, it is better to practice than to learn a hundred things. Only through constant practice can practice make perfect and improve the quality and efficiency of drawing.
