Basic steps of drawing with cad

Because of its universality, CAD is used as a formal drawing software by many factories, units and foreign companies. In general, in order to ensure the compatibility of drawings, only one software is allowed in the same company. For us scholars, how to draw with CAD? Below I have arranged the detailed methods and steps for you.

Methods of general steps in cad drawing;

Basic steps of drawing with cad 1;

1. Create a layer, including the layer name, line width, color and line type. If you don't have the required linetype, click the "Load" button, first load the linetype you need, and 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.

The basic steps of drawing with cad 2:

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

Then read 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 the wire ends are modified. Two weeks should be a small achievement:) Then you can try to draw walls, doors, and be familiar with the commands of array, fill and underline.

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. All these have been done almost, but they still feel ugly and inefficient. You can find a secondary development disk to save trouble, such as Tianzheng, Xinzhou and CAXA. It's better to be in Chinese, which saves trouble and has many fonts.

Wait until 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.

Talking about drawings and standards. In fact, personally, the most important thing in CAD is drawing, not drawing. 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.

You can learn cad drawing well according to your actual situation. But mainly by hard work and persistence.

The basic steps of drawing with cad 3:

1, open the CAD software, and I take "hexagon" and "a straight line" as examples to perform rotation-reference operation. Draw a hexagon and a straight line with CAD. Our aim is to make the inclination of one side of the hexagon CD the same as that of the line segment AB.

2. Move the "hexagon" so that CD and AB intersect at point E ... (It is emphasized here that only intersections can use reference commands. )

3. Enter the rotation command "RO" first, then "Enter", then select "hexagon" and enter according to the prompt. Show bottom left

4. Select the "base point", that is, the intersection point "E", then according to the prompt in the command bar in the lower left corner, enter "R" and press enter.

5. Select "Reference Angle" according to the prompt, and we will select any two points on the CD.

6. According to the prompt in the command bar "specify a new angle", we can click the point on the AB line segment.

7. At this point, we equate the inclination and rotation of CD edge with the inclination of line segment AB.
