You can use the WBLOCK command to help us "streamline" CAD files. Generating a new graphics file from the graphics that need to be transmitted in the form of blocks can reduce the file size to some extent.

There are two ways to solve the problem of large CAD files. One is to reduce the use of small line segments. In the process of CAD drawing, the common tff font is changed to shx single line. Reduce the use of small line segments. Because an arc is also composed of n too short line segments, the graph is too big. The second is the conversion of CAD file format. We generally use the default DWG file format, and DWF format has better compressibility. When transmitting, we can choose to use XUNJIECAD converter to convert DWG into DWF for transmission.
