How to draw with CAD2008 to the process

CAD2008 Drawing Beginner Usage:

1.Some beginners do not achieve good results when learning AutoCAD, which is often due to low learning interest and low learning efficiency. Interest is the best teacher, and when beginners learn AutoCAD, they should treat the process of learning and operation as learning a new video game.

2.The learning process should be done in a step-by-step manner. To learn and master AutoCAD well, we must first know how to draw by hand, and we must be very clear about the geometric knowledge of the drawing method used in the drawing process, so that we can further consider how to use AutoCAD to do it and how to do it.

Practice has proved that AutoCAD is easier to learn and has better results due to strong drawing recognition and geometric drawing ability. Then understand the basic knowledge of computer drawing, such as relative Cartesian coordinates and relative polar coordinates, so that you can master the use of AutoCAD technology from shallow to deep, from simple to complex.

3.One of the great things about learning CAD tutorials is the ability to draw accurately. Precision drawing means that the dimensions are accurate and the drawings are in place.

Parallel lines must be parallel; The vertices of the corners formed by two lines must coincide. When the size is not drawn according to the standard, then the data needs to be modified when marking the size, which not only affects the elegance of the figure, but also directly affects the authenticity of the figure, so it is necessary to be very careful in the process of drawing, step by step, to be accurate and error-free.

4.The purpose of using computer graphics is to improve the speed and efficiency of drawing, and the fastest way to do it is to use shortcut keys. Therefore, when drawing drawings with AutoCAD, you should try to remember and use shortcut keys, and work with both left and right hands, so as to improve the speed of drawing drawings.

When you want to execute a command in the drawing, you can directly enter the shortcut key of the command with your left hand (you don't need to move the cursor to the command line), and then click the right mouse button with your right hand, which is the same as clicking the command icon with the left mouse button.

When learning AutoCAD commands, always combine them with practical application, and don't spend the main energy on learning each command in isolation; It is necessary to apply the principle of applying what you have learned throughout the whole learning process, so that you can have a deep and vivid understanding of drawing commands, which is conducive to cultivating your ability to use AutoCAD to complete drawings independently. I should force myself to do a few comprehensive examples, draw the graphics in detail, so that I can grasp the whole drawing process from the perspective of the overall situation, and strive to make myself able to devote myself to the actual work after learning AutoCAD courses.

1. As shown in the figure below, the top layout diagram is generally viewed from the top and only the top is seen, and the others are deleted.

2. As shown in the figure below, a horizontal figure is drawn, drawing a 45-degree angle. This is the meaning of high marking.

3. Draw another 45-degree angle, as shown in the figure below.

4. Draw a horizontal line, which is changed to green here, mainly for the sake of looking good.

5. In adding fonts, how to add fonts has been mentioned in a few articles. Here +2400 means height, which is the height from the ceiling above the ground.

6. Enter the h key in the command in the spacebar, which is the shortcut.

7. In the selection type is defined by the user, click Bidirectional, and enter 300 in the spacing, where 300 means 300 mm in one grid, that is, the ceiling is 300 mm. In the click Add: Pick Point.

8. In the selection, here only when the seal can be oh, after the selection, click the space to go out of the previous step, click OK.

9. As shown in the figure below, there is a 300*300 lattice, which is the ceiling.

10. After copying some pictures from the gallery, they are marked as aluminum gusset ceilings. This completes the top layout. end

No one said in too much detail on this, such a professional process, how can it be said in a few words, it is recommended to spend one or twenty yuan on ** to buy a CAD compression package, including courseware, and study hard after yourself.

1) Consider whether to draw 2D or 3D;

2) Draw the drawing boundaries first;

3) Draw the main view first;

4) Draw the macro dimensions first, from large to small.

First of all, open the CAD software and enter the font you want to write.

It's best to buy a professional software textbook, it's not clear here.

The next software study is it.

We know that CAD novice drawing must first know how to get started, let me tell you CAD2008 drawing beginner primer, let's learn together.

CAD2008 Drawing Beginner Introduction:

1.Don't read books at first, find a drawing first, draw a scoop according to the gourd yourself, and draw it with CAD for a few days (it is best to use the English version, so that you can learn quickly, and it is good for using software in the future,).

2.Then go to the book, don't read chapter by chapter when you read the book, you can't calculate the area, just look at how to calculate the area, don't modify the line segment, just see how to modify the end of the line, there should be a small success in two weeks :) Then you can try to draw walls, draw doors, and familiarize yourself with the commands of arrays, fills, and labels.

3.When you think your picture is drawn, but it is ugly, but you always feel that it takes a long time and is very troublesome to revise. You can look at exact mapping, layers, blocks, these slightly more complex things. as well as familiarity with elevations.

Sections, structural drawings and much more.

4.Wait for these to be almost done, but I still feel ugly and inefficient, so you can go to a secondary development plate to save trouble, such as Tianzheng.

Xinzhou, caxa, etc., it is best to be in Chinese, trouble-free, and there are more fonts.

5.Wait until you have mastered one of the secondary development software. Basically, it's no problem to deal with 2D drawings, but what you learn is only the basics, and as for 3D drawings, it's best to find a few CAD forums to learn.

6.Talking about drawings and standards, in fact, I personally feel that the most important thing in CAD is to see the drawing, not to make a drawing, a drawing, a model, if you can't understand it, it is not easy to do it at all, and it is full of mistakes to make it. In the same way, when designing drawings, it is necessary to rely on various standards, but looking at drawings and bending Qingchong standards is not something that can be mastered in a few months, which is a matter of fine water and long-term flow.

CAD Drawing Technique Steps:

1.Create a layer, including layer name, line weight, color, line type, if there is no required line type, click the "Load" button, you can load the line type you need first, and create all the layers you need in the map.

2.Determine the expression scheme, start drawing, select the layer to draw the line type, generally draw the center line first, determine the datum, and then draw the buried graphics of different line types in turn, and use the buttons such as trim to complete the shape if necessary.

3.Addition of hatchings. Start by selecting the section type, angle, scale, and then select the section.

4.Dimensioning, including basic dimensions and basic tolerances, geometric tolerances.

Roughness, section symbol.

5.Write technical requirements.

6.Add a frame and title block, and if it is an assembly drawing, label the component number and schedule.

CAD is widely used in mechanical, interior, electronic and other engineering design and drawing fields. So do you know the CAD2008 drawing tutorial? The following is the method of the CAD2008 drawing tutorial that I have organized, I hope to give you an answer.

CAD2008 Drawing Tutorial:

1. As shown in the figure below, CAD 2008 software often selects menu bar, toolbar, drawing and modification toolbar, coordinate system, layout label, command window and so on.

2. Click any - toolbar - click the required toolbar as shown in the figure below.

3. Basic drawing tools, the method of stopping the command: right mouse button, space or back esc key, execute the last command: press the space bar or enter key.

4. Direction coordinate input method:

The x-axis --- horizontal (left for negative numbers, right for positive numbers).

The y-axis --- vertical (negative numbers are down, positive numbers are up).

The z-axis --- perpendicular to the xy plane direction.

5. You can enter rec on the command line and press enter, and a rectangle will appear when you click the mouse and drag.

6. Teach you how to draw well as shown below. The next section talks about how to do CAD drawing. CAD software is not very simple, friends who want to learn CAD well, follow me to learn, you will definitely draw beautiful pictures.

7. The picture below is the final picture we draw.

1. Draw a circle command - specify the center of the circle - diameter 120

2. Draw a circle command - make the same circle center as 120 circles - radius 30; Repeat the Draw Circle command - make the same circle center - diameter 32

3. Draw a circle at the upper end of the 120 circle: pay attention to the radius diameter.

4. Make a straight line at the left and right ends of the R20 circle.

5. Shear, cut off the excess arc, pay attention to the part between the angle between the 120 circle and the straight line.

6. Array, select R20 arc, line, 20 circle, and select the array command.

ar) Select the ring array, select the center point as the center of the 120 circle, and the total number of items is 3<>

OK gets. <>

7. Shear, cut off the excess arc, and it's good.

Hope!

Dafan starts the drawing of a new CAD drawing, the steps are as follows:

One to. The self-programmed command of the lsp applet or prepare a template file to complete the following initialization work1uniform settings of layers;

2.setting of size variables;

3.the setting of the text style (font type);

4.Preliminary determination of the drawing range and linetype scale.

Second, the basic way of drawing: 1:1 drawing.

The scale here refers to the ratio between the value of the drawing unit displayed in the software interface and the size of the physical object being drawn. For example, if the actual length of a segmented wall is 3000mm, then when drawing a straight line representing it, draw it in 3000 drawing units.

There are many advantages to this, first of all, you don't have to use mental calculations, you can draw and modify directly, and you can draw as much as you want; The second is that it is easy to query, there are many things drawn, and the distance between each other can be known at a glance, and it will be clear when you query; The third is that the dimension is convenient and fast, and the size variable does not need to be set up specially, and it can be directly noted; Fourth, after the setting between different drawings is the simplest, it is convenient to splice graphics with each other, which can facilitate the use of existing graphics and greatly improve work efficiency.

3. The reasonable drawing order of this figure is as follows:

1.Draw a double line first. You can start by drawing a horizontal line as a datum for a double line, and then gradually expand the range, using the "line" command, the "offset" offset command, etc"fillet"chamfer commands, and so on.

But note that the size of the line segment needs to be able to determine every day, like you in this graph, there are some dimensions missing, for example, the spacing of the double line, the size of the horizontal double line, etc., everything that is missing should be supplemented, if not, you can set a one, anyway, it is practice.

2.Then annotate the dimensions.

Start at the beginning, then take a single line with the amp size, and finally offset.

Do you want steps or just ask for CAD drawings.
