In this paper we preset an innovative 3D modelling application which consists of our ARCADE modeling system and the Studierstube/VT toolset. Studierstube/VT provides a toolset for intuitive two-handed interaction using pad and pen at a Virtual Table and serves as a the front-end in this integrated system ARCADE/VT. ARCADE is the underlying modeling system, developed having the special requirements of CAD and 3D input as well as 3D output devices in mind. It provides modeling-specific direct 3D interaction techniques. ARCADE/VT follows the idea of Wakl-Up VR. The user can just step in front of a Virtual Table and start to model in free space, no special prerequisites are placed at the user's side.
