Abstract: 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.

Abstract: The present invention describes a distributor plate provided with distribution elements having low sensitivity to a lack of horizontality, a distribution element being constituted by two substantially co-axial cylinders termed the inner cylinder (1) and the outer cylinder, the lower horizontal surface (5) separating the two cylinders being closed. The distributor plate is suitable for co-current downflows of gas and liquid, more particularly in “trickle bed” mode. The invention also concerns the application of the distributor plate to processes for the hydrotreatment or hydrogenation of various oil cuts.
