A computer-implemented tool for manipulating and controlling objects within a three-dimensional (3-D) model includes a modal indication of state for whether to perform an extrusion operation, a tool origin configured to indicate an object defined within the 3-D model, and a tool handle pair including a first handle and a second handle configured such that the first handle and the second handle are linearly aligned along an axis that extends through the tool origin such that the first handle is arrange opposite to the second handle with the tool origin disposed therebetween. The axis Is further aligned and associated with a second axis corresponding to the object such that, in response to an input associated with one of the handles, a processor configured to generate the 3-D model and implement a model editor alters the object indicated by the tool origin. |
