Abstract:
1. A computer-implemented method for designing a CAD modeled object, wherein the method comprises: displaying at least one parametric three-dimensional shape; user-interacting with the screen; defining on a support a stroke corresponding to the user-interacting; computing at least one geometrical characteristic of the stroke, wherein the geometrical characteristic of the stroke includes one or more of a tangent vector of the stroke, a normal vector of the stroke, a first point of the stroke, a last point of the stroke, a center of a bounding box of the stroke, and a position of the stroke; determining at least one parameter of a geometrical CAD operation based on the computed geometrical characteristic, the geometrical CAD operation having inputs comprising one or more displayed parametric three-dimensional shapes, the parameter determining how the geometrical CAD operation is to be performed and including one or more of: wherein, when the operation is a blend, a match or an extrapol operation, the parameter includes the continuity level and when the operation is a blend or a match operation, the parameter further includes the tension.
