A computer-implemented method for selecting an item from a list in a user interface. The method receives a first input from a user. The first input comprises an interaction with an icon displayed on a computer screen. The interaction involves either a first action from the user or a second action from the user different from the first action. Next, if the first input involves the first action, the method displays on the computer screen a first menu comprising a subset of the items of the list. Otherwise, if the input involves the second action, the method displays on the computer screen a second menu comprising the whole list of items. Lastly, the method selects an item of the displayed menu upon receiving a second input from the user.

Computer-implemented method for selecting an item from a list

A computer-implemented method for setting a typed parameter of a typed operation applied to a 3D modeled object in a 3D scene. The method comprises displaying a representation of the 3D modeled object in the 3D scene. The method comprises obtaining the typed operation to be applied on a point of interest of the displayed representation of the 3D modeled object and selecting a first typed parameter among at least two typed parameters, thereby defining the selected first typed parameter as a current selected typed parameter. The method comprises providing a 2D manipulator in the 3D scene for setting the current selected typed parameter and setting the current selected typed parameter upon user interaction with at least one logical area of the 2D manipulator associated with the current selected typed parameters. The method improves the setting of a typed parameter of a typed operation.

Setting typed parameter

A computer-implemented method manipulates a 3D object in a 3D scene of a computer-aided design system, by: (i) displaying a 3D object having a center of rotation in the 3D scene on a screen; (ii) displaying in the 3D scene a rotation manipulator (RM) having three areas (RA, RA, RA) perpendicular to each other, and each area (RA, RA, RA) corresponding to a rotation plane, and (iii) activating the rotation manipulator. The rotation manipulator (RM) follows the cursor (C) on the screen. The rotation manipulator is activated by locking its location on the screen on an initial press point (PP). One rotation plane is selected by displacing the cursor (C) to the area (RA, RA, RA) corresponding to said plane. A rotation manipulation is performed according to the displacement of the cursor (C) on the screen.

Gesture-based manipulator for rotation

According to an embodiment of the invention, there is provided a computer-implemented method for designing a three dimensional modeled object in a three dimensional scene, wherein the method comprises the steps of: providing a first curve; duplicating the first curve to obtain a second curve; determining a set of at least one starting point belonging to the first curve; determining a set of at least one target point belonging to the second curve, each target point being associated at least one starting point; linking the relevant points with their associated target points by using at least a connecting curve.

According to the invention, there is provided a computer-implemented method for duplicating a modeled object displayed on a touch screen and designing its duplicated version in a single gesture. The method comprises detecting () contact of an appendage within an activation zone associated to the first modeled object. If the contact is maintained more than a predetermined amount of time Tm (), the method duplicates () the first modeled object into a second modeled object. The method, while maintaining contact between the appendage and the touch screen, performs at least one design operation () on the second modeled object depending of the movement of the appendage on the touch screen.

A computer-implemented method of setting a parameter. The method comprises detecting a user input on a first location on a graphical user interface, the user input being maintained. The method further comprises displaying on the graphical user interface a pie menu centered on the first location, the pie menu comprising at least one angular sector that is associated with a customizable parameter. The method also comprises detecting a second location of the user input on the graphical user interface in the at least angular sector, and selecting among a set of values, a value of the customizable parameter by displacing the user input from the second location to a third location.
