Among them, there are many cad versions developed in China, such as Zhongwang cad, Chen Hao CAD, HCAD, CPCAD, Tianzheng CAD cad pccad, etc. Maybe everyone has used these versions, and only these versions can add some new functions to cad. Of course, we can understand that these are cracked versions.

So what is the latest cad version? What are the most commonly used and classic cad versions?

Now the latest version: AutoCAD20 14.

Classic version: AutoCAD2004

There are many commonly used versions, and there are also relatively easy-to-use cad versions, including AutoCAD 2004, AutoCAD 2006, AutoCAD 2008, AutoCAD 20 10, and even AutoCAD20 12, which have very strong 3D functions and adopt Ribbon interface. , users are relatively widely used.

What's the difference between all cad versions?

In fact, these versions are almost the same in mistakes, but some functions have been added because of the upgrade of the versions. For example, the high version will add some galleries, add three-dimensional drawing functions, add Auto Lisp assembly language for the first time, and provide a secondary development platform for users to carry out secondary development as needed. These functions are all added in the new version.

CAD software drawing course

When drawing with CAD software, it is often necessary to modify some symbols, such as serial number, schedule data, roughness, shape and position tolerance, welding symbol, chamfer mark, lead mark, center hole symbol, datum mark, cone inclination mark and so on. In this way, we need a flexible tool to achieve our goal, so that our drawing can ensure high quality and high efficiency.

At present, domestic designers are often bound by these complicated tasks and waste a lot of time on retouching, modifying and drawing symbols. Drawing and modifying symbols can be simple. However, once a large number of labels need to be modified and symbols need to be drawn or modified, repetitive work is needed, which makes domestic designers waste their energy and time on unnecessary work.

In order to solve this problem, Chen Hao CAD used GRX technology in its development, and a custom entity was born. Such an object can easily edit and modify its properties, and can create a template for its commonly used entities. When drawing this part again, you can constrain it according to the template (layer, text style, dimension style, custom entity attributes, etc.). ). And when we use Chen Hao CAD Machinery 20 1 1 to modify the symbol, we only need to double-click the originally defined entity to see the originally defined constraint conditions, and we can change the custom entity by changing the constraint conditions.

Let's show you what a custom entity is through the grip editing function:

First, we draw a circle, and then draw a roughness symbol (here the roughness symbol belongs to a user-defined entity).

User-defined entities can realize grip editing. Being able to use the grip editing function to constrain these entities is a highlight of GRX technology in the development and application of CAD in Chen Hao. With the grip editing function, we can paste, copy and mirror symbols more conveniently. At the same time, the attributes in the user-defined entity can also be constrained: the serial number is associated with the schedule in two directions, and either party can interact when modifying it. Automatic generation of schedule and other operations, avoiding the trouble of borrowing between drawings many times before.

However, in general similar CAD mechanical software, even simple grip dragging is difficult to achieve, but the results are often unsatisfactory.

Let's take a look at the grip drag effect in common CAD mechanical software:

From the figure, we can see that the "roughness" after dragging has interfered with the graph.

Then we will use Chen Hao CAD machine 20 1 1 to achieve the same goal:

2

The effect is obvious, and the "roughness" will no longer interfere with the graphics after dragging. Rough blue dots can be adsorbed on the circle, and no matter how you drag them, there will be no ordinary software. This is because custom entities have attribute constraints.

As can be seen from the above example, the custom entities of Chen Hao CAD are widely used in the usual drawing, which can improve our work efficiency. Although this is only a detail application when we draw with CAD, it is the continuous improvement of this detail that constitutes the core competitiveness of 2D CAD application in Chen Hao today when the function of 2D CAD software is difficult to break through.

How to set up the process of CAD software

Set 1- the location needed to create the process.

Three positions are needed in the document release process, namely, R&D manager, R&D vice president and document controller. Considering the future flow of enterprise personnel, it is necessary to maintain the system configuration again. In order to reduce the maintenance workload, it is suggested to set up relevant posts for process participants.

In enterprise configuration > position, select the position grouping of R&D department, and right-click menu create > position to open the position maintenance window, where you can enter position information.

Select the Include Users tab, click the Add button, and then select the Users who will participate in this position.

Setup 2- Process Roles and Process Roles

In order to better manage the rights of process participants, the three-product management system supports editing or adding process roles and process roles.

In system settings > parameter configuration, select the parameter "process role settings" in the process processing class, and right-click menu properties to open the viewing window, where you can edit or create a new process role. These two roles are created in a similar way. The following demonstrates the creation of process roles.

No. 1 1

Click the New button in the view window, and two command items "Process Role" and "Process Role" pop up. We choose "Process Role".

Enter the role name "Document Controller" in the pop-up window, and then click the permission settings related to the permission label. Click "OK" after setting, and the role is created.

Apply 1- to create a process template

Application background:

To realize the standardization of enterprise internal processes through the process management system, we must first ensure that we can customize the process template that fully meets our own management needs.

Pre-application settings:

Need to know: setting 1- creating jobs and setting 2- setting process roles and process roles.

Application steps:

1, in Enterprise Configuration; Select "R&D department" folder in "document template" and right-click menu to create >; Process template, the "Process Template Properties" window will pop up, and enter the template name.

2. Click the "Flowchart Definition" tab to design a flowchart in this window. Click new process > general to open a definition window of general process. Note: If this process involves changing the lifecycle state of a document, it needs to be set as a publish, republish, archive or undo process.

3. In the Process Definition window, enter the process name Approval.

4. Click the Participants tab to set the participants for this process. Sources can be users, posts and dynamic users (recommend posts to reduce the workload of future maintenance).

5. After selecting process participants, the Select Process Role window will pop up. Users can select different process roles according to the actual permission requirements, and then click OK.

6. After setting other processes in the process template in the same way, click the right-click menu to specify the pre-process and post-process to establish the context for all processes in the whole process template, and the process template setting is completed.

Application background:

In the process of enterprise business process execution, it is sometimes necessary to inform some relevant personnel. When setting up a process template, you can set up email notifications in related processes.

Application steps:

1. After the last application operation is completed, select the "Email Notification" tab in the "Process Definition" window, and check the "Email Notification after submitting this process" option to make the following settings, otherwise the other options are grayed out and cannot be selected.

2. Click Add to add a line to the recipient list. Click the ellipsis button in "Fill in the Recipient or Email Address" and select the system user or dynamic user as the recipient. Please note that the "Fill in the recipient or email address" box supports filling in the email address manually.

3. By checking the options behind the address bar, the mail will be sent to the user's system mailbox or to the mailbox (Note: please click "Enterprise Configuration >" to send it to the mailbox; User "information can only take effect if you fill in the email).

Several problems about straight line in Auto CAD software

First, the difference between the concept of straight line and geometry in CAD

Geometrically, a straight line has no endpoints and both ends extend indefinitely; In CAD, this is the concept of construction line. The concept of line segment in geometry is actually the concept of straight line in CAD, that is, two endpoints are needed to determine the length, angle and position of straight line. This problem is often ignored or confused by many beginners, so it is also the first problem to be clearly explained to students in CAD linear teaching.

Second, the calling method and format of the straight line command

1. The calling method of the linear command.

Third, the straight line command three ways to draw a straight line

Because a straight line (a line segment in geometry) has several elements, such as position, angle and length, we can draw a straight line accurately as long as we know that one or several of these elements are combined. For example, as long as the positions (coordinates) of two endpoints of a straight line are known, a straight line can be drawn, and then the angle and length of this straight line can be determined. So there are many ways to draw a straight line, as listed below:

1. Absolute coordinate method.

2. Relative coordinate method.

3. Relative polar coordinate method.

Fourth, make necessary settings for straight lines before drawing.

As the "language" of design communication, drawings must follow certain standards, because the drawing standards applicable to different industries are slightly different. But there is a basic rule in drawing lines, that is, in the process of drawing lines in CAD, different lines, colors and thicknesses are used according to the different meanings of the structure. For example, the axis and symmetry center line are represented by dashed lines, the visible contour lines are represented by thick solid lines, and the dimension line and auxiliary lines are represented by thin solid lines. , and the lines, lines, colors and line widths expressing the same structure in the drawings should be consistent. The standardization of drawing lines improves the accuracy of drawing and brings convenience to drawing and drawing recognition. Therefore, before drawing with CAD, different layers should be set with Layer Manager, and each layer has different line type, color and line width, which can control whether the layer is displayed or edited, thus improving the efficiency and accuracy of drawing complex graphics. In addition, in order to draw straight lines conveniently, we usually turn on the object snap, orthogonal or polar axis to improve the drawing efficiency.

The so-called "sharpening the knife and cutting the wood by mistake", before drawing, according to the needs of graphic expression, set up the line type, line width and color of the drawing line, manage it in layers, and open the necessary drawing auxiliary tools. Developing these good drawing habits is the premise and guarantee to realize accurate, clear and efficient drawing.

Five, choose the right command

(1)LINE command, which is used to draw straight lines in CAD, is the most frequently used and flexible command in CAD.

(2) In order to ensure the correspondence of "long alignment, equal width and high level" among the three views of an object, several auxiliary lines should be drawn with XLINE and RAY commands, and then the redundant parts should be cut off.

(3) If you want to quickly generate a closed filled boundary or construct an area, you should choose the PLINE command. Line segments generated by PLINE can be edited by PEDIT command.

(4) When multiple parallel line segments are generated at one time, and each line segment may use different colors and linetypes, you can choose the MLINE command.

We can control CAD by sending a series of commands. After receiving the command, CAD will immediately execute the command and complete the corresponding function. In the specific operation process, although there are many ways to achieve the same goal, if the command is properly selected, the operation steps will be significantly reduced and the drawing efficiency will be improved.

Sixth, the extension of line drawing in drawing other graphics.
