The first step is to turn on the fast AD converter on the mobile phone. Entering the home page, you can see that there are two major sections, namely, cad version conversion and CAD to PDF. The conversion of CAD from high version to low version belongs to version conversion, and we can click directly to enter.

Step two, this is not the page where the conversion is officially started. This paper briefly describes that cad version conversion under this function can be compatible with multiple versions, and supports preview and annotation of converted files at the same time. Click Start Conversion.

Step 3: First, you need to upload a cad file. If you want to convert to a lower version, you can choose the appropriate version. You can choose AutoCAD 20 13 here, and the output format can also be selected as the original format or DXF format. Then click Start Conversion.

Step 4: Next, the file is being converted. Wait a minute. When you see that the conversion is completed on the page, click the file library to find the page directly and jump to the location of the cad file that has been converted to a lower version.
