A simple tutorial on CAD, how to get started with CAD quickly

Find it yourself, there is a CAD with Xiao Kai on the Internet, good.

It's not difficult to draw some 2D graphics in CAD, as long as you master the basic commands and some shortcut keys. Next, I will tell you the complete set of introductory tutorials for CAD drawing, let's learn together.

CAD Drawing Beginner Introductory Course 1:

In the process of AutoCAD physical exercises, although there can be a variety of calculations to achieve the same purpose, if the command is selected properly, the operation steps will be significantly reduced, and the drawing efficiency will be improved. Here is just one typical example.

Generate a line or segment.

1.In the beginner's introduction to CAD drawing, the line, xline, ray, pline, and mline commands can all be used to generate straight lines or line segments, but only the line command is the most frequent and flexible.

2.In order to ensure the correspondence between the three views of the object, the length is right, the width is equal, and the height is flush, the xline and ray commands should be used to draw several auxiliary lines, and then trim the excess parts should be cut off.

3.If you want to quickly generate a closed fill boundary, or if you want to construct a region, you should use the pline command. Segments generated with pline can be performed using the pedit command.

4.If you want to generate multiple line segments parallel to each other at a time, and each line segment may use different colors and line types, you can select the mline command.

The above CAD tutorials are some suggestions for beginners in CAD drawing, but the most important thing to learn from AutoCAD software is to practice more on the computer and summarize more, and check more relevant books.

Mapping tips.

1.Drawing Steps: Set View Frames Set Units and Precision Create Several Layers Style Objects Start drawing.

2.Drawings always use a 1:1 scale. To change the size of the drawing, you can set different print scales in the paper space when printing.

3.Set different layers, colors, and lineweights for different types of primitive objects, and the color, linetype, and lineweight of primitive pairs should be layer-controlled.

4.When you need accurate drawing, you can use the raster snapping feature and set the raster snap spacing to the appropriate value.

5.Don't draw the frame and the figure in the same picture, insert the frame in the layout as a block, and then print the picture.

6.For named objects, such as views, layers, blocks, linetypes, text styles, plot styles, etc., the naming should not only be concise, but also follow certain rules to make them easier to find and use.

7.Set common settings, such as layers, dimension styles, text styles, raster snaps, and more, in a drawing template file (i.e., save as *.).dwf), later when you draw a new drawing, you can create a new drawing wizard and click "Use Template" to open it and start drawing.

If you want to learn CAD, you must first learn three views.

CAD is purely a backrest software! There are no shortcuts.

Here's how to get started with the CAD tutorials:

1.Some beginners do not achieve good results when learning AutoCAD, which is often due to low learning interest and low learning efficiency. Interest is the best teacher, and when beginners learn AutoCAD, they should treat the process of learning and operation as learning a new video game.

2.The learning process should be done in a step-by-step manner. To learn and master AutoCAD well, we must first know how to draw by hand, and we must be very clear about the geometric knowledge of the drawing method used in the drawing process, so that we can further consider how to use AutoCAD to do it and how to do it.

Practice has proved that AutoCAD is easier to learn and has better results due to strong drawing recognition and geometric drawing ability. Then understand the basic knowledge of computer drawing, such as relative Cartesian coordinates and relative polar coordinates, so that you can master the use of AutoCAD technology from shallow to deep, from simple to complex.

3.One of the great things about learning CAD tutorials is the ability to draw accurately. Precision drawing means that the dimensions are accurate and the drawings are in place. Parallel lines must be parallel; The vertices of the corners formed by two lines must coincide.

When the size is not drawn according to the standard, then the data needs to be modified when marking the size, which not only affects the elegance of the figure, but also directly affects the authenticity of the figure, so it is necessary to be very careful in the process of drawing, step by step, to be accurate and error-free.

4.The purpose of using computer graphics is to improve the speed and efficiency of drawing, and the fastest way to do it is to use shortcut keys. Therefore, when drawing drawings with AutoCAD, you should try to remember and use shortcut keys, and work with both left and right hands, so as to improve the speed of drawing drawings.

When you want to execute a command in the drawing, you can directly enter the shortcut key of the command with your left hand (you don't need to move the cursor to the command line), and then click the right mouse button with your right hand, which is the same as clicking the command icon with the left mouse button.

CAD is used for two-dimensional drawing, detailed drawing, design documentation and basic three-dimensional design, is one of the must-learn drawing software for designers. Many people actually don't know a lot about this software, so let's share the beginner's tutorial on CAD drawing.

Open the CAD softwareOpen the CAD software and set it to classic mode.

View the drawingLeft-click Draw in the menu to see a submenu with drawing tools.

Select a toolLeft-click the drawing area to draw a line segment using the Line tool.

Draw a line segmentDraw an arcSelect [Arc] in the drawing tool to draw an arc.

Enter textAfter drawing the arc, select the text tool on the tool to enter the text.

Step 1

To familiarize yourself with the functions of each icon, hover over the icon and a prompt will appear at intervals of one second.

Step 2

Ask someone with experience, or buy a book or take an online tutorial.

Step 3

Familiarity with drawing functions; Use different drawing tools by selecting icons.

Step 4

Learn the modifier function: Use different modifiers with the selection of icons.

Step 5

Once you are satisfied with the modifications to the drawing, you can save it.

Step 6

Personalization can be modified using the "options" command.

1. We first draw two auxiliary lines to determine the position of the center of the circle.

2. Use the circle tool to draw a circle with diameters of 14 and 28 directly.

4. After drawing the auxiliary line, we can draw several circles as shown below.

6. After using the construction tool, enter the Use Tangent, Tangent, and Radius commands on the command line to specify the first tangent point between the object and the circle and the second tangent point between the specified object and the circle. We can draw it.

7. Use the Fillet tool, enter a radius of 21, select the object, and press Enter.

8. Then use the trimming tool to trim off the excess lines.

9. According to the radius of the circle is R14 and the straight line of 58mm and 49mm. The center of the circle of R14 can be drawn, and in the same way, a circle with a diameter of 14 can be drawn. Finally, you can connect the other lines.
