According to your description, you are having problems using CAD.I suggest that you first try to uninstall the CAD software and perform anti-virus operations, and then reinstall the CAD software.If the problem persists, it may be caused by an incompatible operating system. According to my understanding, Windows 7 may not be suitable for CAD because it is not compatible with CAD system files.Some users have also reported similar problems, but the solution is to reinstall the operating system and CAD software. In addition, you can check whether the save options are set correctly.If the saved settings are correct but the problem still exists, you need to consider reinstalling the operating system to solve the problem. Conclusion: In case that the CAD software crashes and cannot be started normally, please try to uninstall and antivirus first, and reinstall the CAD software.If the problem still exists and cannot be solved, please consider changing to another operating system with better compatibility (such as Windows XP) and reinstalling.At the same time, make sure that the save options are set correctly to avoid the risk of data loss.
It should be that the version of the CAD software you installed is faulty. It is not authentic.Or you may cause software damage during use after installation
There are two kinds of fatal errors: 1. When opening, fatal errors occur: when opening cad, it will regenerate the model first, and then some graphs will make fatal errors. You just need to press esc to stop it from regenerating. 2. Fatal error in saving: This may be caused by software piracy, so you should always save the drawing when you draw it. Do not save it until the drawing is complete. If a fatal error occurs at this time, you will have to regret it.
