How to quickly learn and master the basics of CAD

If you pay more attention to shortcut keys in CAD, you should first find some quick answers to the functionality of the tool, and then deepen your learning through simple examples (architectural drawings or mechanical drawings, etc.). It is best to buy a more basic and detailed book to study as usual or go upstairs to provide the "enet" online to see the ** tutorial will benefit a lot, to have regular and patient learning, maybe a day or two can not see a lot of progress, learning is a gradual process. Hold on!

You follow the drawing while watching the ** teaching, and then the foundation will open the picture and follow the drawing little by little, so that you can learn it quickly. And when you know how to draw some, just see how others draw it, learn it, and soon you will become a master.

1. We must first prepare the paper required for drawing, the size of the paper from A0 to A4 is decreasing in turn, the drawing can be divided into whether there is a gutter, the frame is left with a gutter The general binding edge is 25mm, and the other three times are equal to the distance between the boundary lines.

2. The whole paper can be divided into two areas: drawing area and title bar; The title box should be placed at the bottom right of the drawing, providing a true description of the drawing and indicating the author information.

3. The font used in the drawing is different from the font usually used, which is divided into straight (that is, the font we usually use) and italic (the sesame oil is oblique, 75 degrees from the horizontal line).

4. The font size is divided into: A B font, the width of the A-type font is one-fourteenth of the height, the width of the stroke of the B-type font is one-tenth of the height of the word, and the same font is used for the same pattern.

5. The requirements for various drawing lines are also very high, and we must fully understand the graphic characteristics of various graphics for the use of various graphics, so as to clearly reflect the structural characteristics of the physical object (note: the gap between the two parallel lines shall not be less than, when drawing the circular center line, the intersection of the center of the circle must be the intersection of solid lines; The center line less than 12mm can be replaced by a solid line instead of a double-dotted line; There should be a gap where the thick and thin solid lines meet.

6. Two of the unique nouns need to be especially understood, and they will often be encountered in drawing operations. Slope: tana = h l taper refers to the ratio of the diameter of the bottom circle of the cone to the height, if it is a taper, the difference between the upper and lower bases is the ratio of the upper and lower height, that is, the taper = d l = d l - d l = 2 tana.

There are many skills that need to be mastered to learn CAD, shortcuts, tutorials, etc., rote memorization is impossible, the main thing is to be proficient in hands-on operation!

Indoor drawing: such as the lamp position, the general operation is to start from the beginning, a lamp and a lamp landmark, in fact, the mark a head and a tail, the middle mark as a whole, and then modify the characteristics, find the size text instead, directly enter the "spacing * quantity = <>" The system will directly fill in the measurement data. This way the picture is clear and the number is easy to count.

The usage of the design center ADC: ADC is more suitable for the drawing of interior design construction drawings, if there are too many blocks and drawings, you can not remember them all, open the design center, you can see all the block files, select the required block, and drag it directly into the drawing.

Mouse use: You can try double-clicking the middle button; Press the middle button and drag, which is equivalent to the gripper tool; Execute the Tools-Options-System Configuration command to cancel the right-click shortcut command to realize right-click confirmation and repeat.

Centerline drawing: The centerline operation can be used in the elongation tool in the drawing, add de; Execute Linetype-Load-File-Notepad Open-Find the corresponding linetype, enter the number change, you can change the linetype of the center line to comply with the national standard.

X-rays can be changed to XX; Set the label to dd; The cloud is set to rr

Tutorials for beginners, take a look.

If you stick to ten articles a day, within ten days, become proficient in the use of commands.

Learn to look at pictures.

Learning CAD to read drawings is the first step, you have to learn to understand the drawings, understand its logic, this is the first step in CAD entry.

When looking at drawings, you need to pay attention to its annotations, dimensions, basic geometric knowledge, etc., which you can learn from books first.

Naturally, we also need to see the picture, and we are not looking at paper pictures.

Memorize shortcuts.

After learning to read pictures, we can gradually start to operate. As soon as the novice opened the device, he was completely confused. Then you can start with the operation of shortcut keys to understand drawing.

Practice makes perfect.

No matter what skill you learn, what kind of industry you do, you can't go wrong with practicing on the right path. Let go and learn, practice makes perfect, your sweat will never betray you!

See more and summarize more.

Look at other people's drawing operations, learn more from your predecessors' drawing skills, and most importantly, summarize your own mistakes and experience.
