please look at the image attached and help me remember.
on the left side of the picture I created a snap shot from the drawing itself. like PNG.
the right side is a simple drawing view, so if someone will change/suppress a part from it, you will see the updated drawing view
but in the snap view (which i did sometime ago and don't remember how) The picture will remain even though it is changed/suppressed.
it is not made by "sketch picture" because i can't edit it. i can't get any information of how it was taken.
i know i can solve this by inserting a picture, but i really want to know if someone's know the answer.
