Practical CAD skills, finally know why others use CAD faster than me

1.How do I replace an unfound original font?

Copy the font to be replaced as the font name to be replaced, for example: open a picture, prompt no font jd found, you want to replace it, then you can go to the AutoCAD font folder (font) to copy a copy of it, rename it, and then put it in font, and reopen this diagram on it. In the future, if you open a diagram that contains a jd font that you don't have on your machine, you will never have to keep looking for fonts to replace.

2.How do I remove a stubborn layer?

Method 1: Turn off the useless layers, select all, copy and paste them into a new file, and those useless layers will not be pasted. If you have defined a block in this unwanted layer and inserted the block in another layer, then the unwanted layer cannot be deleted in this way.

Method 2: Select the graphics you want to leave behind, then select File Menu - > Export - > Block Files, such a block file is the selected part of the drawing, if there are no specified layers in these graphics, these layers will not be saved in the new tile drawing.

Method 3: Open a CAD file, close the layer you want to delete first, leave only the visible graphics you need on the surface, click File - Save As, determine the file name, and select * in the file type columnDXF format, click Tools-Options-DXF option in the pop-up dialog window, then tick the selected object, click OK, and then click Save, you can choose to save the object, select the visible or desired graphics to be saved OK, exit the file you just saved when you're done, and then open it to see, you will find that the layer you don't want is gone.

Method 4: Use the laytrans command to imply the layer to be deleted as 0 layers, this method can delete layers with solid objects or defined by other blocks nested.

Find a specific engineering drawing, draw it yourself, watch the master draw it, and draw it again.

The level has increased.

I think it's better to practice more, practice makes perfect.

CAD is just an operating software, if you have basic mechanical knowledge, it should be easier to learn. CAD is just a tool for engineers, replacing the original manual drawing, with easy modification, easy to copy, can be enlarged and reduced at any time, and there are some pre-defined library functions in the software library, which reduces the workload and is easy to use compared with manual drawing.

The key is to learn by heart, to be able to quickly see the structure of equipment or parts, and to master some of the most commonly used commands.

Quickly master the methods of AutoCAD:

Before learning CAD, it is necessary to have a solid basic knowledge of reading and reading drawings, and understand the expression methods of various views. The knowledge of reading and reading drawings is the premise of learning CAD.

Buy a book to learn AutoCAD, read more about the introduction of some basic knowledge in Biyun, follow the example drawings explained in the book, summarize more, and take more notes.

Proficient in some commonly used commands, and understand the use of sub-commands contained in commands, there are about 40 commonly used commands. If you don't understand any commands, you can check the AutoCAD help (press F1 to get out), which has a detailed description of the usage of each function.

Proficiency in the use of layers. Layers are set up to manage different categories of graphics, for example, the basic floor plan of a city is placed in one layer, the layout of urban underground water pipes is placed in one layer, the floor plan of urban power lines is placed in one layer, and the water pipeline is placed in one layer, when you need it, you can make which layer is displayed, which layer is not displayed, which layer is printed, which layer is not printed, you can set the characteristics of the graphic objects in each layer separately, in short, there are many uses of layers.

5.As long as you draw more and think more, everyone will become a master.

First of all, we must have a systematic understanding of the CAD interface and functions, and Yuhong should not draw drawings with straight line commands at the beginning.

After choosing a tool for choosing a town and choosing a town, pay attention to the prompts in the command line window below. Follow the prompts.

Just take this CAD basics to get started, and it should be good in a week.

2.After another 2 days of exploration, go to the bookstore to buy a book with related supports, so that you can learn more purposefully through the textbook. This teacher can be a book or a many**.

First of all, you need to have a book to get into the fight, but don't follow the examples in the book.

3.It is necessary to summarize some methods and memorize some commonly used shortcuts. With a little more time, some assignments will be easier to pick up.

5.First draw some simple and low-difficulty pictures, so that you can have a sense of comfort and achievement, and print them out to commemorate it. Then, as you get the command and tools right, you can draw complex diagrams.
