A computer-implemented method and system of computer-aided design products for dynamically manipulating an assembly of objects in a three-dimensional scene. The system and method provide the assembly of objects with information relative to kinematic joints linking objects of the assembly. The system and method provide a dynamic manipulating tool (DM) embedded in the scene. The DM tool includes a 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 attach said dynamic manipulating tool (DM) to one object of the assembly, and select a degree of freedom of the dynamic manipulating tool (DM) attached to the object of the assembly. The system/method apply a load according to said selected degree of freedom and calculates and displays in real-time the result of a dynamic simulation of said load applying.

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 (PPP) 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.

A computer-implemented method for designing an assembly of objects in a three-dimensional scene of a system of computer-aided design, comprising the steps of: providing (SI), in the scene, a first locator (LOCI) associated with a first design dimensions range; and providing (S), in the scene, at least one second locator (LOC, LOC) respectively associated with a second design dimensions range, the first design dimensions range having an upper bound greater than the upper bound of the second design dimensions range.

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 (S) the assembly of objects with information relative to kinematic joints linking objects of the assembly. The system/method provide (S) a manipulating tool (M) embedded in the scene; attach (S) said manipulating tool (M) to one object of the assembly; select (S) a degree of freedom of the manipulating tool (M) attached to the object of the assembly; and input (S) 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 (S) and display in real time the dynamic simulation taking into account the initial conditions (IC) previously defined.

A computer-implemented method and apparatus of designing an assembly of objects in a system of computer-aided design. The method/apparatus provides a three-dimensional geometrical modeled object comprising at least one three-dimensional geometrical element; provides a logical modeled object comprising at least one logical component; and associates sets of at least one three-dimensional geometrical element with respective sets of at least one logical component. The method/apparatus display in a three-dimensional scene, a representation of a set of at least one logical component partially superimposed on the corresponding associated set of at least one three-dimensional geometrical element.
