CAD systems are powerful software tools used to manage numerical edition and simulation of products. Edition of CAD objects is a fundamental step in the lifecycle of these products. Although CAD benefits from improvements in functionalities, user interaction on these systems does not evolve anymore. Our goal is to propose novel haptic techniques to enhance user interaction with such applications. An important issue in CAD systems is the modification of the Boundary Representation (B-Rep) of 3D objects. Our general goal is to determine suitable haptic methods to increase accuracy of 3D interaction with CAD objects. This paper focuses on CAD edition processes based on parameterization of extrusion operators.
