A computer-implemented method of displaying a subset of a digitally modeled assembly (A) of objects (O1, O2, O3), the method comprising the steps of: a) generating and displaying a three-dimensional graphical representation of the assembly in a three-dimensional scene (3DSC); b) using a graphical tool (PT) for selecting one or more objects of said assembly from said three-dimensional graphical representation; c) determining a central point (CP) of the selected object or objects, and computing a distance of each object of the assembly from said central point; and d) modifying the displayed three-dimensional graphical representation of the assembly by hiding objects whose distance from the central point exceeds a threshold, or reducing their visibility. A computer program product, a non-transitory computer-readable data-storage medium and a Computer Aided Design system for carrying out such a method.
