Abstract: A computer-implemented method for creating an animation summarizing a design process of a three-dimensional object, comprising the steps of: a) acquiring design data during at least one design session; b) automatically identifying time points of said session or sessions corresponding to milestones of the design process, and storing data representing statuses of the three-dimensional object at said milestones; and c) generating and displaying an animation of the design process, including displaying a graphical representation of a timeline (B) providing access to milestone data. A computer program product, non-transitory computer-readable data-storage medium and computer system for carrying out such a method.

Abstract: A computer-implemented method for assisting a positioning of a digitally modeled 3D object including obtaining a first digitally modeled 3D object having a 3D position in a 3D scene, rendering a projection of said first digitally modeled 3D object on a screen according to a first axis and a first viewpoint, and while modifying, upon user action, the 3D position of the first digitally modeled 3D object along the first axis, automatically scaling the first 3D object in order to keep constant the projection of the moved object on the screen.
