Enter "Imageclip", press enter, select a picture, the option appears, press enter, press enter.

"P", press enter, and prompt for the first point. At this time, you need to leave a continuous point on the edge of the picture.

Click, (a bit like the use of a pen in Photoshop) until you finally enter "C" and close.

Do it.

However, it should be noted that the original drawing cannot be relocated or deleted, otherwise there will be no such drawing in cad.

In this way, you can put your picture signature or logo into cad.
