Introduction scheme of cad drawing, cad drawing has applications in many industries, such as furniture design, decoration design and so on. The most widely used are machinery industry and construction industry. The following is the entry scheme of CAD drawing.

Introduction of cad drawing plan 1

Beginner course of cad drawing (basic of cad drawing for beginners)

First, understand the CAD drawing steps

1, get all the dimensions of the sample to be drawn, no matter what you draw, the dimensions should be complete;

2. Building a layer is equivalent to several transparent papers, and their relationship is independent and related;

3, the layer is set, and then go down to find the anchor point of the drawing, draw the center line and some auxiliary lines;

4. Then start painting, and pay attention to making good use of the layers when painting;

5. After drawing, mark it and explain some special parts;

6, proofread the graphics, if there is no problem, you can plot.

Second, learning CAD video courseware

Theoretical knowledge is not enough. If you can watch video courseware to practice, your learning efficiency will be higher. Because in the video, we can see the actual operation steps and effects, and we can practice with the video by ourselves.

Where can I find CAD video courseware? Just open a browser to enter Swift CAD official website, and then click CAD Tutorial in the navigation bar, which contains CAD Zero Foundation Tutorial and CAD Introduction Proficiency Course.

The course is divided into many chapters and each lesson is a knowledge point. I learned CAD from it, which gave me the feeling that the teacher explained it in detail and explained the principle. When you have a clear thread, it is particularly easy to master.

Quietly telling you, you can get CAD video courseware for free at the end of the article.

Fourth, learn to use layers correctly.

There is a default layer in CAD, which is layer 0. We can create solid line layer, auxiliary line layer, center line layer, labeling layer and so on. It is best to set colors and linetypes to distinguish layers.

In addition, there are three useful tools:

Lock: When a layer is locked, it can be displayed, drawn and made as the current layer, but no objects can be modified.

Freeze: When a layer is frozen, it cannot be displayed, drawn, current layer or modified.

Switch: When the layer is closed, it will not be displayed. You can draw and make the current layer, but you can not modify it, but you can delete it with parameters.

Set the layer and draw in it. The requirements for layers, colors, linetypes and printing are as follows:

Layer Settings of General Architectural Drawings:

Summary after class

1, master some commonly used commands, and understand the usage of each parameter, that is, 20~40 commands, other commands can be understood, and try to draw and practice by yourself against the CAD video courseware.

2. Learn by doing. I have been using CAD for years, and I don't quite understand some commands. When I use it, I will read materials and do it step by step according to the textbook. I must pay attention to it and think more.

3. Be familiar with the usage of layers, take notes as much as possible, and learn textbooks from scratch. If you can't learn, learn from scratch. The advantage of studying in this way is that you can find classics in casual places.

1, legend

Different materials need to be represented by different legends, but the use of legends needs to be based on a certain floor area ratio. Here, I'll give you some legends commonly used by design institutes.

Legends commonly used in architectural design

Legends commonly used in architectural design

For the drawing of legends, Chen Hao CAD Architecture and Chen Haoyun Architecture Software also have intimate applications, and you can set them according to different drawings.

Drawing CAD plane

Generally, you can change the drawing scale to display the related legend of the wall. Its type can generally be set by default, or it can be set manually if it needs to be modified.

Draw CAD profiles and details.

You can use the Fill command to draw a legend. The filling pattern of Chen Hao CAD software contains all the legends, which can be directly filled with corresponding materials.

Specification for architectural CAD drawing

Draw legends of building components such as walls, doors and windows.

Because Chen Hao CAD Building has made these building components into parametric objects generated synchronously in 2D or 3D, and their corresponding legends meet the national standards, we can directly choose to insert them.

2, drawing number and naming

The numbering and naming of engineering drawings are actually related to the drawing filing rules of enterprises and design institutes, and the latest specification in 17 is closer to the actual use of design institutes. The specific criteria are as follows:

The specific regulations of different design institutes are different, but they are close to the latest specifications. Take "Jianshi-1-0 1- Design Description" as an example:

for instance

Architecture: architecture major

Stone: This is the drawing in the construction drawing stage.

1: indicates a part of a graph, such as a design description part, a plane part or a horizontal and vertical section part.

0 1: indicates which drawing in a part has a number.

Design Description: Drawing name.

3, axis, shaft number

There are many detailed rules about axis and axis number, which are difficult to remember. However, Chen Hao Construction Software has completely integrated this part of the specification into the software, and it is basically a matter of one or two seconds to mark the axis network.

Compared with simple manual labeling, software automatic labeling is not only more neat, but also dozens or hundreds of times faster. For specific commands, you can learn the grid labeling command (shortcut zwbz) and drawing grid (shortcut hzzw) in Chen Hao CAD architecture and cloud architecture. Of course, designers still need to have a certain understanding of the specification itself.

Specification for architectural CAD drawing

Specification for architectural CAD drawing

Because there are many walls in the building, when drawing the grid, don't use one axis to represent all the walls. You only need to use the axis to locate the main wall column, otherwise the axis network will be messy.

In addition, architecture majors can add an additional shaft in advance, which is convenient for later structural majors to add columns. For additional shafts and shaft numbers, Chen Hao Construction Software also has corresponding commands conforming to the specifications, which can quickly add, delete and even rearrange shaft numbers with one click, which is very convenient!

Learning CAD

I. Introduction to Software

Nowadays, more and more graphic image design software is applied to the daily work of graphic design and students' study. At present, the widely used softwares are CorelDraw, Photoshop, AutoCAD, Illustrator, 3dsMAX, etc. CorelDraw is one of the design softwares favored by graphic designers. Is a set of graphic design, drawing, text editing, production, high-quality graphics output as one of the vector drawing software.

CorelDraw is a professional drawing software developed by Corel Company in Canada. CorelDraw has been modified several times and is now widely used. It was launched in February 2004. CorelDraw is a vector drawing software.

Second, CorelDraw application

The application of CorelDraw involves advertising design, packaging design, fashion design, typesetting and artistic creation design.

1, advertising design

Advertising: In short, extensive publicity refers to the purposeful and extensive publicity activities of language, words, images and other media to the public, such as alcohol advertisements and mobile phone advertisements.

2.CI design and logo design

CI design is the abbreviation of CorporateIdentitySystem. It is a unified design of corporate culture and business philosophy, which is conveyed to the internal and public of the enterprise by using the overall expression system (especially the visual expression system), so that it can have a consistent sense of identity with the enterprise and form a good corporate image, with the ultimate goal of bringing better economic benefits to the enterprise.

Logo In the computer field, Logo means Logo, which is an abstract visual symbol of an enterprise or product. It is the basic element of CI design.

3. Poster design

Posters, also called posters or posters, belong to outdoor advertisements, and are also called instant street art abroad, such as advertising leaflets and mobile phone advertising leaflets in communication squares.

4. Assembly design

Food packaging, drug packaging, product packaging and packaging design are important parts of product marketing, and the quality of packaging plays a very important role in product sales.

5. Book binding design

Exquisite book binding design can make books attract readers' attention better, while layout design can help readers read the text better. Different layout designs can make books have different styles.

6. Drawing of illustrated cartoons

For example, some cartoons, cartoon characters and so on.

Third, the image type.

1, bitmap: Also called bitmap, an image is composed of pixels, and each pixel has a clear position and color value. Bitmap software includes Photoshop and drawing software.

2. Vector diagram: Also called vector diagram, it uses objects such as straight lines and arcs to describe image files. Every object has its own attributes, such as size and position, which will not be distorted when magnified.

Cad beginner drawing steps 1. First, draw the model diagram according to the ratio of 1: 1. Note that the CAD unit is millimeters, and the unit needs to be converted;

2. Then square the picture frame according to the density of drawing lines. Under 100, use A4 box; under 200, use A3; under 400, use A2; under 800, use A 1; over 800, use A0. After selecting a frame, set the scale by dividing the size of the original picture by the size of the frame. For example, a picture of 15m is placed in the A2 frame, and 15m, that is, 15000mm divided by the height of the A2 frame 594, is approximately equal to 25, and the ratio is at least set to 1:.

(1): Click to insert drawing frame:

Insert drawing frame

(2): Select the drawing frame, and then set the scale:

Set the scale and format.

3. Finally, mark the figure, size, technical requirements, precautions, filling, etc.

After completing the above steps, the drawing is completed.

Simple cad drawing entry steps simple cad drawing entry steps

Simple entry steps of cad drawing, cad drawing has applications in many industries, such as decoration design, furniture design and so on. Of course, the machinery industry and the construction industry are the most widely used. The following are the entry steps of simple CAD drawing.

Elementary steps of simple cad drawing 1

As a beginner, the first thing to do is to understand the software CAD, the function, interface and operating tools of this software.

After understanding this, we can do some simple drawing first. Learning CAD starts with drawing a straight line. We can enter the shortcut key "L" and press enter, and then we can see the prompt on the command line to specify the first point.

Let's click on the canvas as the first point and move the mouse to see a line, but it's not straight, is it?

We see that there is an orthogonality below. Click on it, turn on Orthogonality, and then move the mouse to see that straight lines can only appear in the form of straight lines. Click another place as the end point, and then find that the line is not broken. Press spaces to break straight lines.

Then we learn to draw a circle. Enter the shortcut key "c" on the command line, and then we can see the prompt, whether to draw a circle at three o'clock or at the bright spot, or we can click directly, and a circle can be enlarged or reduced at will. At this time, we can enter the diameter of "200" at the command line, and enter the car to see a circle with a diameter of 200.

Clicking each drawing icon will display the corresponding prompt on the command line. We can practice more and learn to draw. Some simple things, such as "mirror image" offset and array, are commonly used.
