    Abstract: 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.

    Abstract: Embodiments provide methods and systems for modifying a finite element mesh representation of a three-dimensional model. A method according to an embodiment defines a symmetric constraint of a finite element mesh where the finite element mesh is a representation of a subject 3D model and the symmetric constraint comprises two asymmetric zones of the finite element mesh to be modified symmetrically. Next, corresponding finite elements between the two asymmetric zones are identified and a manipulation to at least one of the identified corresponding finite elements is performed. In response, the manipulation is performed symmetrically on a second or more of the identified corresponding finite elements where the second or more finite elements were identified as corresponding to the at least one finite element. In such an embodiment, performing the manipulation symmetrically results in the two asymmetric zones being modified symmetrically and represents a symmetrical modification in the subject 3D model.

    Abstract: The disclosure notably relates to a computer-implemented method for designing a three-dimensional (3D) model. The method includes obtaining a first 3D model, the first 3D model being defined by: (i) one delegated data object comprising input parameters specific to a type of the delegated data object and (ii) an output topology, and being associated with a sequence of geometric design operations. The method also includes performing, by a user, a first geometric design operation on the first 3D model, thereby obtaining a second 3D model, determining whether the output topology of the second 3D model can be retrieved from the output topology of the first 3D model, replacing the first delegated data object by a second delegated data object if the output topology of the second 3D model cannot be retrieved from the output topology of the first 3D model or keeping the first delegated data object and storing the first geometric design operation with the sequence of geometric design operations associated the first 3D model.

    Abstract: Computer method and system draws a 3D object, by sketching at least one first stroke (ST1) in a first plane (PL1) rendered in a first viewing frustum corresponding to a first pose of a virtual camera. The first plane (PL1) is orthogonal to a second (PL2) and a third plane (PL3). In response to a command of a user switching from the first pose to a second pose of the virtual camera, the method and system switches from the first viewing frustum to a second viewing frustum corresponding to the second pose of the virtual camera. The second viewing frustum is bounded by a near plane on the side of the virtual camera. Next a plane is selected as current drawing plane. The selected plane is among the first (PL1), the second (PL2) and the third plane (PL3), whose normal is the closest to the normal of the near plane. At least one second stroke (ST2) is then sketched in the current drawing plane.

    Abstract: Embodiments provide methods and systems for modifying a finite element mesh representation of a three-dimensional model. A method according to an embodiment defines a symmetric constraint of a finite element mesh where the finite element mesh represents a subject 3D model and the symmetric constraint comprises two asymmetric zones of the finite element mesh to be modified symmetrically. Next, corresponding finite elements between the two asymmetric zones are identified and a topological manipulation to at least one of the identified corresponding finite elements is performed. In response, the topological manipulation is performed symmetrically on the identified finite element corresponding to the at least one finite element. In such an embodiment, performing the manipulation symmetrically results in the two asymmetric zones being modified symmetrically and represents a symmetrical topological modification in the subject 3D model.
