Sketching, as an intuitive tool for creation and edition of 3D prototypes, is a topic of increasing interest to the community. These approaches are based on the natural ability of humans to quickly draw in 2D some characteristic curves of 3D objects. Unfortunately, some 3D modeling operations - like positioning different components - and the modeling in front of large displays have still not reached the same level of intuitively in sketching systems. The main difficulty is to leverage the intuitive 2D gesture abilities of humans and lift them to XGCT sensical 3D operations. In this project, we present a new approach, based on a virtual 3D paper sheet metaphor and the use of a 6 degrees of freedom (DOF) device. With the associated interaction processes and visual feedbacks, it allows the user to quickly create and edit some sketched 3D models.
