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.

Abstract: Methods for forming a Reuleaux shape from a material involving placing the material into a container, moving the container along an orbit until the motion of the container along the orbit causes the material to assume a Reuleaux shape, and removing the Reuleaux shape from the container. Devices for transforming material into a Reuleaux shape, including a wheel, a platter mounted on the wheel, and a container mounted on the platter. Kits for forming a Reuleaux pentagon, including material having sand and silicone and a hexagonal container.

Abstract: 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 (S2), in the scene, at least one second locator (LOC2a, LOC2b) 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.

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.

Abstract: 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.

Abstract: An assembly for picking and transporting nano-objects, comprises a cassette having first and second components, which are provided with means of mutual assembly and with means for holding the filter. The first and second components define, when the components are in an assembled configuration, a cavity in which the filter is housed and held therein. The means of mutual assembly comprise first clipping means secured to the first component, second clipping means secured to the second component and able to collaborate with the first clipping means so as to clip the two components together. A picking device comprises suction means to which the cassette is able to be removably attached. The first and second clipping means are configured such that they are not accessible from the outside when the components are in the assembled configuration with the cassette fixed to the device.

Abstract: 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.
