Lateral and vertical transformations observed in the study. Lateral transformations can occur through modification of an existing sketch, or through the creation of a new sketch inspired from an existing sketch, to create a new idea. Vertical transformations can occur through adding details such as dimensions,  annotations, or features to an existing sketch, or through a new sketch showing a different detail, to develop an existing idea.
