Hello , can somebody say me how to make in adobe-illustrator white circle transparent in center of red background?
Various ways to do it, but this is the simplest:
- Draw a red square, then draw a circle on top of the red sqaure.
- Then go to Pathfinder (if it's not on your screen already then go to Window -> Pathfinder), and click on Minus Front
Whatever is in front will be taken away from the object in the back.
