Then click on "File" - "Print" in the upper left corner and select related options such as drawing, printer, paper format and orientation in the print window.

Finally select the file save directory and make sure the file type is PDF, click the "Save" button.

This converts CAD drawings into PDFs via AutoCAD. However, when you need to convert multiple CAD drawings at the same time, such a single print conversion is somewhat inefficient. So, here's a more efficient CAD conversion method for you.

(2) Using an online converter

This method requires an online tool called "Swift CAD Converter" to find its website directly by Baidu search.

"Quick CAD Converter" supports CAD to PDF, CAD to JPG, CAD version conversion and other functions. According to current needs, we choose the "CAD to PDF" function.

"Click to select file" to add CAD to the web page, you can hold down the Ctrl key to add multiple CAD files.

After the addition is complete, you can also "continue to add" or directly click "Start Conversion".

Wait a while, CAD will be converted to PDF.

For a chestnut, you use the CAD drawing made by CAD2014, and then open it with CAD2007. This kind of error message often appears:

Problem: Low-level CAD software cannot open high-level CAD drawings.

(3) The drawing file is invalid

Problem: The dialog box "Invalid graphic file" appears after opening the drawing.

Solution: This is because the CAD file is damaged and it is difficult to repair. You can only check if there is any file saved automatically before, or modify the file extension of CAD.
