Basic course of cad drawing

We often use plan drawing in cad, so do you know the basic course of CAD plan drawing? The following is the method of the basic course of cad drawing that I have compiled, hoping to give you an answer.

Basic course of cad drawing;

1. Create a layer, including its name, line width, color and line type. If you don't have the required row type, click? Load? Button, you can load the required linetype first, and then create all the required layers in the drawing.

2. Determine the expression scheme, start drawing, and select the linear layer to be drawn. Generally, draw the center line first, determine the benchmark, and then draw different linear patterns in turn. If necessary, use buttons such as Trim to complete the drawing.

3. Add section lines. First select the section type, angle and scale, and then select the section.

4. Dimensions, including basic dimensions and basic tolerances, shape and position tolerances, roughness and section symbols.

5. Write technical requirements.

6. Add drawing frame and title bar. If it is an assembly drawing, mark serial number and parts list.

The method of learning CAD plan;

1. Don't read a book at first, first find a drawing, draw a gourd ladle by yourself, and draw it in CAD for a few days (it is best to use English version, so that you can learn quickly and it will be good for using software in the future).

2. Then read a book. When reading a book, don't read chapter by chapter. You can't calculate the area. It depends on how to calculate the area and how to modify the line segment. It depends on how to modify the end of the line. There should be a small success in two weeks:) Then you can try to draw walls, doors, be familiar with arrays, fill and underline these commands.

3. When you think your picture has come out, but it is ugly, but it always takes a long time and is very troublesome to modify it. You can look at accurate drawings, layers, blocks, which are a little more complicated. And familiar with elevation, section, structure, etc.

4. When all this is done, but it still feels ugly and inefficient, you can find a secondary development disk to save trouble, such as Tianzheng, Xinzhou, CAXA and so on. It's better to be in Chinese, which saves trouble and has many fonts.

5. When you are familiar with a secondary development software. Basically, it is no problem to deal with two-dimensional drawings, but what you have learned is only the basics. As for three-dimensional drawing, it is best to find several CAD forums to learn.

6. Talk about drawing pictures and standards. In fact, personally, the most important thing in CAD is to look at pictures, not to draw pictures. If you can't read a drawing or a model, it's not easy to do at all, and it's also flawed. By the same token, we should follow various standards when designing drawings, but drawings and standards can't be mastered in a few months, which is a long-term problem.
