Some easy to use tips for mechanical CAD

1. Find the right direction of learning.

If you want to learn through books, you should first set your own learning direction, whether it is graphic design, engineering drawing, mold, material design, etc., and choose books or training according to your actual needs, after all, the books on the market are now very finely classified.

2. Don't rely too much on learning tutorials.

When you are initially learning, you can see more and visit some CAD-related official **, or open classes, which will indeed be helpful to everyone, but also more practical operations, and further learning through books, after all, some of the best tutorials are too detailed and intuitive, and we are easy to lose the ability to think and learn after reading too much.

3. Master the basic commands of CAD.

CAD drawing, how important it is to master the shortcut operation commands, you must know that when learning CAD, you can organize these commands into a document and save it, or take a photo to keep it, and memorize it from time to time. If necessary, you can also write down to deepen your memory, and you can practice while operating.

4. Be diligent in drawing and persevere.

If you have watched the tutorial thousands of times, but you have not drawn it yourself, then you really can't understand the true meaning of it, after all, looking at the plenum, it is possible to do all the work, and the learning process may be a little boring, but as long as you persist, you will definitely have a harvest.

Precautions for using CAD.

1. Select the object method.

There are two kinds, one is from the top left to the bottom right, the other is from the bottom right to the top left, the results of the two ways are different, the first is to select the box that is pulled out, the object that is completely enclosed; Second, all objects that intersect with the imaginary frame, including the objects that surround them, can be selected only if they are to be touched.

2. Layer mode.

The layers of the drawings are like the layers of transparent film on the outside of the cover of a book, and in order to better manage all the objects, each sheet has a different category of objects drawn on it. In order to avoid complicated and wrong graphics during the drawing process, you can close the ones that you don't need for the time being, or lock them, freeze them, and so on.

The software is very suitable for novices, supporting CAD DWG, DXF, DWT and other common drawing formats. It is also possible to convert between files.

There is a software self-learning network on the Internet, you can enter it and find it, it is very useful, there are self-learning tutorials for various software, and the idea of explaining is very clear.

Mechanical drawing is actually a more difficult subject, drawing mechanical drawings with CAD is more complicated, friends who are interested in this can take a look at the following tutorial on CAD mechanical drawing beginners, which may be helpful for you to learn CAD mechanical drawing.

1.Proficiency in some commonly used commands, and understanding the use of each parameter, is 20-40 commands, <>

2.Master the shortcuts of common commands, and understand some commands.

3.Learn by doing, and then review the materials to learn as you go.

4.Compare the textbook step by step, do it repeatedly, and be sure to pay attention to looking back and thinking more.

5.Proficiency in the use of layers.

6.Try to take as many notes as possible in your studies, learn the textbook from the beginning, and if you can't learn it, learn it again from the beginning. The advantage of learning in this way is that you can discover the classics in casual places.

7.Stress is also a motivation for academic progress.

1. Double-click the CAD startup sign to create a new SC with empty bands

2. Click "Insert" in the toolbar in CAD

3. Select "XRef Manager" in the drop-down menu, and a dialog box will pop up.

4. Click "Attach" in the above dialog box, and the "Code Selection Slide Reference File" will appear, select the floor plan that needs to be referenced, and click "Open".

5. Next, an interface will pop up, select "Relative Path" in the path type, this path is conducive to the automatic connection of drawings in the future. For example, if you copy from one computer to another, neither the full path nor the no path can automatically identify the reference basemap, and the relative path can be automatically recognized.

6. Click "OK", and the reference is done. Later, if someone else modifies the reference basemap, you can simply replace the reference.

Before learning mechanical CAD software, you must first learn mechanical drawing.

Because mechanical drawing is the basic preparation car. Let me tell you more about it.

How to teach yourself CAD mechanical drawing

1. To learn mechanical drawing, we should pay attention to cultivating our spatial imagination, look at objects more, and it is best to analyze objects according to the drawings of objects.

2. It is necessary to practice often, the methods and skills of drawing are accumulated little by little in ordinary times, and when you are proficient, you can use it with ease.

3. Simplify complex problems. In order to accumulate some structure in ordinary times, first put three views of the simple structure.

Understand it, and then try to put it together. We can think of a complex combination as a combination of simple structures, and complex diagrams, as long as you look at them at a deep level, only the simple structures in your mind remain.

4. Learn how to draw standard parts and common parts, the drawing method of standard parts and common parts is often simple to make paragraphs, but pay attention to their drawing methods, for beginners, this is the most error-prone place, for example, thread and thread connection is a noteworthy place.

5. Pay attention to learn the expression methods of sectional scrolling diagrams, cross-sectional diagrams, and local enlarged diagrams!

6. Careful, cartography is a meticulous job. The position and length of the line are required to be drawn carefully; Don't miss lines and don't draw more lines, this is the highest and most basic requirement!

7. Look at the standards, learn and apply, and practice to bring true knowledge.

There are 3 learning channels for self-paced CAD:Now there are a lot of teaching resources about CAD on the Internet, you can search for CAD-related knowledge on the Internet, and there are many CAD gods who explain CAD-related knowledge, which is very useful.

2.Buy books to learn: There are many books about learning CAD, and books can be carried around, making it more convenient to learn.

3.Into the training class: no matter what major there are large and small training courses, you can sign up for training courses to learn, the advantage of the training course is that there is a teacher to explain that the learning will be faster, the disadvantage is that the training course is generally more expensive, and a certain economic ** is required.
