Abstract: It is provided a computer-implemented method for designing a CAD modeled object. 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; determining at least one parameter of a geometrical CAD operation based on the computed geometrical characteristic. Such a method makes the design of a CAD modeled object easier.

Abstract: It is provided a computer-implemented method for designing a CAD modeled object. The method comprises displaying at least one three-dimensional parametric shape; user-interacting with the screen; defining on a support at least one stroke corresponding to the user-interacting; selecting a number of the three-dimensional parametric shapes; evaluating a relative position of the stroke with the selected shape; and determining a geometrical CAD operation based on the number and the relative position. Such a method makes the design of a CAD modeled object easier.

Abstract: It is provided a computer-implemented method for designing a CAD modeled object. The method comprises displaying several three-dimensional parametric shapes on a screen, wherein each of the several three-dimensional parametric shapes is divided in several portions, a different design operation being assigned to each portion; user-interacting with the screen; determining one portion upon a location of the user-interacting on a support, the determining being performed among all the portions; and performing, on the shape to which the determined portion belongs, the operation assigned to this portion. Such a method makes the design of a CAD modeled object easier.

Abstract: A method and system for aiding a user of a graphical object editor in defining inputs for a selected command comprises presenting a navigation console on the display in response to a user selecting a particular command. The navigation console contains information which is contextually related to the selected command and, in particular, shows a sample object having sample features representative of the command inputs and additional features showing the command output using the sample input features. The console display has active regions associated with respective command inputs which cover one or both of a sample feature associated with the respective command input and an icon representative of the respective input. When a user selects an region in the navigation console associated with a particular command input, the command processor state machine is shifted to a state appropriate to receive a definition of a feature in the main object model for use as the particular command input.
