Why are there problems with the CAD data posted on the forum?

Why are there problems with the CAD data downloaded on the forum? I have experienced this many times. Last time I downloaded the 50W tons of methanol data in the data area. I read the posts and they all said it was good. But when I downloaded it, it prompted me that the graphic file was invalid as soon as I opened it. This happened again with the ammonia evaporation file this time... Is there something wrong with my computer? It shouldn't be possible... or what's going on? > Anyone who has downloaded these two data, can you check it after downloading????
When the graphics file is invalid, it is usually because your CAD version level is not enough. For example, CAD2006 files cannot be opened in the CAD2004 environment. To be on the safe side, it is recommended to upgrade your CAD to 2008 so that all files can be opened.
If you do not want to upgrade the CAD version you are currently using, you can download a CAD version conversion tool from the Internet to convert CAD files created with a higher version into a lower version format so that they can be opened. The files in the forum have been verified and will not be unable to be opened.
