1. A method for converting a sketch shape into a semantic element, the method comprising the steps of: receiving a request to convert a first sketch shape into a first semantic element, wherein the first sketch shape and a second semantic element are part of a first nested shape combination, wherein the first sketch shape includes a visual depiction corresponding to a first class of semantic descriptions, wherein the first semantic element is a visual depiction further including a first semantic description of the first class of semantic descriptions; determining that a first semantic relationship between the first semantic element and the second semantic element exists; and based on determining the first semantic relationship converting the first sketch shape to the first semantic element, such that the determined first semantic relationship is depicted between the second semantic element and first semantic element; wherein at least one of the steps is carried out using a computing device.
