How do beginners learn CAD and how should beginners get started?

Article 1: Choose the appropriate software.

Maybe you don't hesitate to choose AutoCAD, but I advise you to give up, because the commands inside are in English, as a beginner, without understanding the operation of the software, you must first be familiar with the English commands, which is more difficult for beginners. Here it is recommended to use Haochen CAD, this supports Chinese commands, the operation of the software is no different from AutoCAD, after mastering, you want to use AutoCAD can also be used instantly, of course, maybe your future company is using Haochen CAD, because now many state-owned enterprises are using this domestic non-open source CAD.

Article 2: Proficiency in the use of the mouse.

In computers, the mouse is an important part, in CAD drawing, the left mouse button generally performs the operation of selecting the graphic entity, and the right mouse button displays the operation of the shortcut menu.

Article 3: Operating Habits.

When we operate any computer software in the process, there will always be some operating habits, there are good and bad, just learn CAD, the author recommends the left hand to hit the keyboard, the right hand with the mouse.

Article 4: Down-to-earth and lay a good foundation.

Practice more and draw more. I have tutorials for free

Here's how to learn:

1. First of all, if you want to learn to use CAD, you must be proficient in using the computer, the flexibility of the mouse and keyboard is a must, there are many instructions in the CAD that need to use shortcut keys, so the more familiar you are with the computer, the easier and smoother it is to learn. After touching CAD, many need to use shortcuts, and we will talk about CAD shortcuts and their importance later.

3. The basic knowledge of CAD must be mastered, such as the layout of the CAD interface, where the coordinates are, what tools are used in the toolbar, the methods of confirming and exiting commands, etc., mastering these is conducive to further learning. These can be found in online tutorials and free **. There are also basic tutorials in the CAD software help.

YY's operation interface is very similar to QQ, and it can be used directly.

4. Mastering the operation of CAD and making CAD drawing standards and specifications is not only a procedural thing, but also needs to be taught by people with experience in the industry, or go to the construction site to learn immersively, and run more building materials market.

5. CAD tutorials have a lot of resources on the Internet, it depends on how we choose. YY voice teaching is now more advanced and easy to use method, you don't need to go out of the house to open YY to learn in class, save time and efficiency, and real teachers explain, not afraid to see ** no one problem.

The importance of shortcuts, only the real industry knows the importance of shortcuts in CAD drawing. Not only does it speed up your drawing, but it also makes you look professional in the eyes of your customers. For example:

F1: Get help.

f2: Switch between the drawing window and the text window.

f3: Controls whether to implement automatic object snapping.

F4: Digitizer control.

F5: Isometric plane switching.

f6: Controls how coordinates are displayed on the status line.

F7: Grid display mode control.

F8: Orthogonal mode control.

f9: Raster snap mode control.

F10: Polar mode control.

F11: Object Tracking Mode Control.

Answer: To be basically familiar with engineering drawing CAD, it is relatively simple to start from the four aspects of standard, drawing, annotation and printing, which is suitable for explaining the production of tutorials and convenient personal management of the ruler solution, which is not comprehensive. In addition, because my level is average, I try to explain it in detail so that it is easier to understand.

1. Standards (just understand it simply, it's not too important, know that there is it.) ）

Engineering drawing includes three types: equipment drawing, flow chart, and layout drawing. The general equipment diagram includes the main view and the top view of the device. The layout plan must indicate the orientation.

Standards mainly talk about drawing standards, including national standards, industry drawing standards and so on. For example, the national standard stipulates the marking of welds. Another example is the production standard of our chemical drawing title block, parts list, etc.

There are also rigid regulations such as the thick line of the material pipeline line in the drawing process, and the diameter of the instrument circle is generally 10mm.

But generally these are not very important, in the actual process of doing a good job, as long as the drawings are clearly expressed, the content is clearly expressed in the abbreviated diagram.

2. Drawing. CAD drawings are mainly made with the help of the tools in the CAD Drawing Toolbar and the Modify toolbar. During the use of drawing tools, combined with the auxiliary operation of the status bar, you can complete the production of drawings faster.

The most commonly used states are orthogonal, polar, and object snaps. Others that are not commonly used are not introduced one by one.

Hello! CAD beginners can find some CAD basic practice questions, generally there will be simple drawing steps next to the nucleus, according to the Bixu steps to draw, familiar with the basic operation of rubber CAD.

Beginners of CAD need to master the four methods of learning in the mode of learning in the point and area mode, using the flipped classroom model world-selling learning, stringing into a line of summative learning, and learning to modify the function.

1. Learn in a point-to-area mode

CAD is a very operable software, so it is necessary to use the case method to learn and consolidate the CAD software through cases. In the case, you can choose general mechanical drawings, such as graphics composed of straight lines, graphics composed of circles, and graphics composed of straight lines and circles, and other more complex drawings are not considered.

2. Adopt the flipped classroom mode of learning

There are three steps in the flipped classroom: offline preview, classroom learning, and offline review. Offline preview can go to the Internet to search for the corresponding CAD** learning, offline review can go to the Internet to search for the corresponding case** for CAD drawing, if you have participated in the staff, the classroom learning can use the Internet different CAD teachers** as the main class.

3. Summative learning in a line

No matter how you learn, you need to know what you need to learn next, otherwise, without systematic learning, the brain will not apply the CAD knowledge that has been learned the day before yesterday or even yesterday, and you can't string the knowledge together, so you must have an outline to learn CAD software, so that each point can be strung into a line after learning.

4. Learn to modify the functionUse different modification tools by selecting icons.
