How to convert cad into pdf format

1. First, we need to open cad, then open the drawings to be converted into PDF format, and put the drawings to be printed in the center of the screen, as shown in the figure.

2. Then we can start to turn to PDF. First, select the print option at the top left of CAD, and a print dialog box will appear, as shown in the following figure:

3. There is a drop-down window in the "Page Setup" of this dialog box, and we select the "Last Print" option. As shown in the figure:

4. Next, there is a drop-down window under "Printer/Plotter". We click on it, and we choose "DWG? To PDF. PC3 "option,

5. Next, we need to select the paper size we want to print in "Paper Size", for example, I choose A4 paper.

6. We also need to have a drop-down menu "Print Range" under "Print Area". Let's click and select the window.

7. Click the "Window" option next to the drop-down menu, and such an interface with grayed or darkened colors will appear. We can select the drawing to be printed by the cursor.

8. After selection, the following dialog box will appear. At this time, we need to check that the drawing direction is in the lower right position, which is "portrait" and "landscape". When we choose landscape orientation, there is a preview box under the "Properties" option, and we can see the printing effect of the drawing.

9. After adjustment, we select Print, and a dialog box will appear to let us choose the location to save. For example, I choose the desktop here and click the Save button in the lower right corner. We can see that the file format in the "File Type" column of the dialog box is already in PDF format, as shown in the figure below:

10. Click Save and a small window of "Print Job Progress" will appear. We just need to wait quietly for the printing to be finished.

1 1. After printing, we can view the converted drawings through PDF or WPS to check the printing effect.

Extended data:

In addition to computer software, such as operating system and compiler, CAD mainly uses three kinds of software: interactive graphic display software, CAD application software and data management software. By 20 14, Chen Hao CAD and Zhongwang CAD, which are rising rapidly in China, have high compatibility with AutoCAD and are also one of the choices of users.

Interactive graphic display software is used for window opening, editing and viewing, graphic transformation and modification, and corresponding human-computer interaction. CAD application software provides geometric modeling, feature calculation, drawing and other functions to complete various special designs in the fields of machinery, advertising, architecture, electricity and so on.

The four elements of constructing application software are: algorithm, data structure, user interface and data management. Data management software is used to store, retrieve and process a large amount of data, including text and graphic information.

Therefore, it is necessary to establish an engineering database system. Compared with the general database system, it has the following characteristics: the data types are more diverse, the entity relationship in the design process is complex, the values and data structures in the database often change, and the designer's operation is mainly a real-time interactive processing.
