What to do if the cad plug-in is loaded successfully but cannot be used

When the CAD loading plug-in is successful but cannot be used, it may be caused by the following reasons:

1. Version mismatch: Make sure that the plug-in you download and install is compatible with the CAD software version you are using. Sometimes, plug-ins may not be compatible or work properly with a specific version of CAD software. Please check the compatibility requirements of the plug-in and ensure that the plug-in matches your CAD software version.
2. Plug in configuration problem: some plug-ins need additional configuration to work properly. Please ensure that you have set up and configured the plug-in correctly. Some plug-ins may have specific settings or options, and you need to configure them according to the instructions provided by the plug-in.
3. Permission problem: If you log in CAD software under a restricted user account, the plug-in may not work properly. Try running the CAD software with administrator privileges to get enough privileges to use the plug-in.
4. Corrupt or missing file: The plug-in file may be corrupt, missing, or deleted. Try reinstalling the plug-in to ensure that it is properly installed and located in the specified path.
5. Other conflicts: Some plug-ins may conflict with other CAD plug-ins or functions, resulting in failure of normal use. Try disabling other plug-ins or features, and check whether plug-ins can be used.
6. Missing dependencies: Some plug-ins may depend on other components or library files. Ensure that you have correctly installed and configured the required dependencies, such as NET Framework, Java Runtime Environment, etc.
7. Plug in function restrictions: Sometimes, plug-ins may have specific function restrictions or only apply to specific scenarios. Please check the documentation or instructions of the plug-in to understand its functions and usage restrictions.

If the above methods are invalid, it is recommended to consult the technical support of CAD software or plug-in developer for more detailed help and support.
