1, open AutoCAD, in the toolbar, select Tools - Load Application.
2, in the pop-up load/unload application dialog box, select the plug-in to be installed, and then click on the plug-in to be installed, click Load.
3, the bottom left corner of the window on the prompt has been loaded. Here plug-ins can be installed, but so that every time you open a new CAD, you have to load a plug-in. This is very inconvenient.
4, you can click on the contents of the startup group, in the pop-up startup group dialog box, click Add, once again to find the installation path to install plug-ins, click Add. This will eliminate the need to repeatedly load the plug-in.
5, re-open CAD, enter the application shortcut command, so you can use the plug-in.
