14 karat gold wholesale jewelry As long as CAD has the initial method of starting, then it can be improved soon. Let me tell you the introduction of the CAD drawing. Let's learn together.
CAD graphics Beginning entry method 1. Some beginners have poor grades when learning AutoCAD, which often causes low learning efficiency due to low learning interests. Interest is the best teacher. When studying AutoCAD, beginners should take the process of learning and operation as a new video game.
2. The entire learning process should be stepped forward. To learn and master AutoCAD, we must first know how to draw pictures by hand. The geometric knowledge used in the drawing method in the drawing program must be very clear. Essence Practice has proved that the ability to recognize the map and geometric drawing is strong. AutoCAD is easier to learn, and the effect is better. Then learn about the basic knowledge of computer drawing, such as relative right -angle coordinates and relative polar coordinates, so that you can master the use technology of AutoCAD from simple to deep, from simple to deeper.
3. One of the advantages of learning the CAD tutorial is that it can draw accurately. Accurate drawing refers to accurate size and in place. The parallel line must be parallel; the angle composed of two lines must be reunited. When the size is not drawn according to the standard, the data needs to be modified when the size is marked, which not only affects the elegance of the picture, but also directly affects the authenticity of the picture. , To be accurate, no error.
4. The use of computer drawing is to improve the speed and efficiency of the drawing. The fastest way to operate is to use shortcut keys. Therefore, when drawing graphics with AutoCAD, try to remember and use shortcut keys, and work on the left and right hands to improve the speed of drawing graphics. When you need to execute a command in the drawing, you can directly enter the shortcut key of the command directly with your left hand (no need to move the light marker to the command line), and then click the right mouse button with your right hand. of.
For example: To execute the mobile command, you can input "M" with your left hand (when entering the command in the command line, you do not distinguish between the case), and then click the right mouse button to execute the mobile command. Common command shortcuts such as: offset "O", fill "H", cut "TR", extend "ex", write blocks (blocks used in different graphics files) "W", multi -line text "T" , Give up (one step back operation) "U", translate "P" in real time, create an arc "A", straight line "L", the window zoom "z", decompose "X", create a circle "C", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B", create a block "B". ", Insert into the block" i "; the key to commonly uses: capture" F3 ", orthogonal" F8 ", the polar axis" F10 ", and the object tracks" F11 ". Give beginners a simple suggestion, trying to use quick commands to draw the graphics you practice at the beginning of learning AutoCAD.
5. When learning the autocad command, always combine with the actual application. Do not spend the main energy on various commands to learn; With a deep and image understanding, it is conducive to cultivating its ability to complete the picture independently to complete the drawing. To force yourself to do a few comprehensive examples, draw the graphics in detail, so that you can master the entire drawing program from a global perspective, and strive to enable yourself to study the autoCAD classes and you can enter the actual work.
The techniques of CAD drawing 1. Follow a certain drawing principle
(1) Steps: Set the range → set the unit and accuracy → create several layers → set the object style → start drawing.
(2) Drawing 1: 1 ratio. In order to change the size of the pattern, a different print ratio can be set in the drawing space when printing.
(3) Set different layers, colors, and line widths for different types of graphic objects, and the color, line type and width of the pair of graphic pairs should be controlled by layers.
(4) When you need to draw accurate drawing, you can use a grid capture function and set the grid capture spacing to appropriate values.
(5) Do not draw the frame and graphic in the same picture. You should insert the frame in the layout and print out the picture in layout.
(6) For famous objects, such as views, layers, blocks, line types, text styles, print styles, etc., not only must be concise, but also follow a certain rule in order to find and use.
(7) Set some commonly used settings, such as layer, label style, text style, grid capture and other content in a graphical template file (that is, separate as*.dWF). Create a new graphic wizard and click "Use Template" to open it and start drawing.

2. Selecting the right command
During the specific operation of AutoCAD, although there can be a variety of calculations that can achieve the same purpose, if the command is properly selected, the operation steps will be significantly reduced. Improve drawing efficiency. Only one typical case is listed below.
In straight lines or line segments
① In the initial entry of CAD drawing, use LINE, XLINE, Ray, PLINE, MLINE commands can generate straight lines or line segments, but only the LINE command uses the highest frequency, and the most is the most. flexible.
② In order to ensure the corresponding relationship between the three views of the object "long, wide, high and flat" between the objects of the object, the XLINE and RAY command should be selected to draw several auxiliary lines, and then the excess part is cut off with Trim to cut off the excess part Essence
③ To quickly generate a closed -filling boundary, or if you want to construct a noodle area, you should use the PLINE command. Editors can be edited with the Pedit command generated by PLINE.
④ When multiple parallel line segments are generated at a time, and each line may use different colors and line types, you can choose the MLINE command.
