It seems like your text got a bit jumbled. If you're referring to how an artist might use basic shapes to create a drawing that confuses the eye, it's likely about utilizing techniques such as abstraction or optical illusions. By breaking down complex objects into simplified forms, the artist can play with perceptions, leading viewers to see something unexpected or to interpret the image in multiple ways.
If your question is something more specific or if there's a particular context you're looking for, please provide more details!
