First, hardware preparation

If you want to do a good job, you must sharpen your tools first. First of all, there should be a suitable computer on the hardware. Of course, it is necessary to run AutoCAD normally. Of course, if you want to draw comfortably, you need a mouse and keyboard. I think the minimum requirement is that the mouse cannot drop frames. As far as the keyboard is concerned, try to choose a keyboard with concave-convex keys and good flexibility. These two things are like kitchen knives in a chef's hand to a draftsman. A blunt knife will definitely affect the chef's feeling and speed of cooking.

Second, use shortcut commands.

If you ask an AutoCAD draftsman this question: What is the most important thing to improve the drawing speed? I think many draftsmen will answer you like this: use shortcut commands to solve problems as much as possible.

Let's illustrate: there are several ways to draw a straight line. Many beginners click the line tool on the toolbar with the mouse, and then draw a line in the drawing area of AutoCAD with the mouse. A professional draftsman will use his left hand to enter the shortcut command "L" for drawing a straight line on the keyboard, then confirm it with a space, and then the mouse will draw this straight line in the drawing area. If you are a beginner in AutoCAD, then I will give you a simple suggestion. At the beginning of learning AutoCAD, try to use shortcut commands to draw your own practice graphics.

Some friends may suggest to find the file "acad.pgp" in the folder of AutoCAD and modify it into their favorite shortcut command. I don't recommend beginners to adopt this method from the beginning. In fact, when learning the basics, the commonly used shortcut commands are very simple and easy to remember.

Let's take the command to draw a straight line as an example. Beginners can't remember or don't know that the shortcut command for drawing a straight line starts with "L", so we move the mouse to the straight line button on the drawing toolbar and stop the mouse at this position. Notice that a straight line prompt will appear in the status bar under AutoCAD: Create a straight line segment: straight line. Here we know that the complete command of a straight line is "line".

Instead of clicking the straight button on the toolbar with the mouse, try to enter the first letter "L" of the command directly on the command line and click the space to confirm the command (think about why we use spaces to confirm the command). Find the command prompt: the L line specifies the first point. In this way, we know that the shortcut command for drawing a straight line segment is "L", so we will try to use "L"+space on the keyboard instead of clicking the toolbar with the mouse. You will find that we will remember this shortcut command after repeating it many times. Is it simple?

Similarly, we can get the shortcut command "C" for drawing a circle, "A" for drawing an arc, "O" for offset, and "M" for moving ... But some shortcut commands can't be found like this. For example, we know that the complete command for drawing a rectangle is "rectang", but the command we get by inputting the shortcut command "R" is "REDRAW". Try to enter "RE" again, the command is "REGEN", try to add a "c", enter "REC" again, and the shortcut command for drawing a rectangle is "rec". Through the above method, we can find that the shortcut command for constructing lines is "XL", the shortcut command for multi-segment lines is "PL" and the shortcut command for arrays is "AR". This kind of learning is very fast in the initial practice. If you are a beginner of AutoCAD, try to do your basic AutoCAD exercises in this way. You will find that as long as you use this method repeatedly, your AutoCAD drawing speed will increase quite quickly.

Third, the left and right hands have their own duties.

Here, the right hand and the left hand perform their respective duties, which means that the left hand controls the keyboard and the right hand controls the mouse (unless your dominant hand is the left hand). And strive to maintain this state in practice and future work. Then there is an answer to the above question: we put our left hand on the standard key position of "ASDF", and our thumb can easily click the space bar to confirm the command. If we have to click Enter to confirm the command, we need to move the position of our left hand greatly. Which way is faster? I don't need to elaborate.

Here's another example of the same reason: deleting objects. Many friends who are new to AutoCAD use the Delete key to delete objects in drawings, but the author's habit is to use the shortcut command "e" with spaces to delete objects. Why? From a mathematical point of view, maybe we have another keystroke here, but we can make a choice by looking at the positions of these keys on the keyboard: if we put our left hand on the standard key position "ASDF", it is very easy to point the "E" key with the middle finger and point the space with the thumb, but the Delete key is far from the standard key position of our left hand. If we click this key with our left hand or right hand, and then reset our hand, it will take much longer than if we click the "E" and then click the space bar, which is why we use these two keys instead of the Delete key.

Fourth, look down at the keyboard as little as possible.

It is hard to imagine that a person who always needs to look down at the keyboard can operate the computer very skillfully. I believe that friends who study AutoCAD are familiar with computers, so before reading this article, you'd better ask yourself: Do I often look down at the keyboard?

Many friends are familiar with keyboards, but often for psychological reasons, such as worrying about pressing the wrong key, they always bow their heads to confirm. Remind everyone: don't worry about pressing the wrong key! Don't look down These will be big problems that will affect your drawing speed in the future! Be sure to use the fingers of your left hand instead of your eyes. It doesn't matter if you make a mistake. Don't try to avoid mistakes by looking at the keyboard, nor try to correct your own mistakes by looking at the keyboard.

Try to point out the key points with your left hand several times and practice it several times. In fact, many friends are slow to learn AutoCAD because they have too many habits that they dare not try, or they are worried about making mistakes. If you want to make real progress, you must not worry about making mistakes, but have the courage to try. If you can make more valuable mistakes, you can learn more than you seem to follow the rules!

Verb (abbreviation of verb) self-check and improvement

Self-check for further improvement. There is a term in chess called double-player game, also called "double-player game". It refers to the key to play back the record of the game after the game, so as to check the pros and cons of the game and the gains and losses. Generally used for self-study, or ask experts to guide the analysis. In fact, this method can also be used to improve AutoCAD learning.

After the drawing of simple graphics has come to an end, click F2 on the keyboard to open the AutoCAD text window and watch your drawing process step by step: which steps can be improved; Which steps are invalid and wasteful operations, and you can not do them next time; I can use mirrors or arrays to simplify the steps. Is it complicated? Is there an easier way to make this picture? After doing this work repeatedly, you will find that this process is a process of standardizing your painting habits and prompting yourself to think. Such a "duplicate disk" is very helpful for us to find a "shortcut" in the process of drawing.

Sixth, continuous accumulation.

Accumulate. Learning itself is not achieved overnight. Skills can be accumulated continuously, but accumulation has no skills. If you want to be a master, you must keep learning and accumulating, and of course, more importantly, learn to apply it. Maybe one day, you will find yourself a "prawn".
