Abstract
A method and system for manipulating a three-dimensional object in a computer-aided design (CAD) environment utilizes a force feedback interface. A gravitational sphere is defined around each of the plurality of input parameters of a mathematical model defining a shape, location and orientation of the object. A force is applied to the force feedback interface based on the gravitational spheres and the position of the force feedback interface. An input signal is received from the force feedback interface based on the applied force indicating selection of one of the plurality of input parameters. The selected input parameter can then be edited according to an edit signal generated by the user via the force feedback interface. In addition, the edit signal can be limited according to predetermined constraints via the force feedback interface.
