Abstract: A computer-aided design system and computer-implemented method define initial conditions for dynamic simulation of an assembly of objects in a three-dimensional scene of a computer-aided design. The system and method provide (S1) the assembly of objects with information relative to kinematic joints linking objects of the assembly. The system/method provide (S2) a manipulating tool (M) embedded in the scene; attach (S3) said manipulating tool (M) to one object of the assembly; select (S4) a degree of freedom of the manipulating tool (M) attached to the object of the assembly; and input (S5) at least one initial condition (IC) according to said selected degree of freedom, an initial condition comprising an initial position and/or an initial speed and/or an initial acceleration. The tool has a referential (reference) with three-axes allowing for each axis a degree of freedom in translation and a degree of freedom in rotation. Next the system and method calculate (S6) and display in real time the dynamic simulation taking into account the initial conditions (IC) previously defined.

Abstract: A computer-implemented method for computing an envelope (BE) for a building to be designed, the method comprising: defining an initial volume (IV) of the building; and for each one a plurality of points (P1, P2, P3) of a boundary (PRB) of a neighboring region (PR) of the building, computing a cutting surface (CS) and modifying the initial volume by cutting out portions thereof extending above said cutting surface; wherein each cutting surface is defined in such a way that the initial volume, modified by cutting out portions thereof extending above it, projects over the corresponding point of the boundary a shadow (SW) whose duration is equal to a predetermined value; said envelope being defined by a boundary surface of a remaining volume. A computer program product, a non-transitory computer-readable data-storage medium and a Computer Aided Design system for carrying out such a method.
