Abstract: The present invention relates to a computer-implemented method, a computer program product, and a server for positioning a structural element in a 2D section of a CAD structure. The invention is characterized in that at least two distances, each distance in between an alignment line of the structural element and a parallel reference line of the 2D section, are displayed on a user visualization means and dynamically updated as the location of the structural element within the 2D section is changed. In a preferred embodiment, the reference lines are dynamically chosen based on the location of the structural element within the 2D section.

Abstract: In a first aspect, the current invention provides a method for manipulating a computer aided design (CAD) model, comprising the following computer-implemented steps of: —obtaining a composite object comprising a 3D geometry; —defining a 2D cross section of the composite object; —selecting a pattern of an event; —displaying the pattern; —applying modifications to the pattern, whereby the modifications are saved as a 2D patch, directly linked to the 3D geometry. The method according to an embodiment of the invention is particularly suitable for linking the maps providing 2D details, used on a construction site, to 3D composite objects and is particularly useful to avoid incompatibilities between the 2D and 3D information. In a second aspect, the present invention provides a computer program product for manipulating a CAD model. In a third aspect, the present invention provides a server for manipulating a CAD model.

Abstract: The current invention concerns a method, a system, and a computer program product for suggesting a detail in a building information model. Based on an initial identification of a detail in relation to two construction elements in a building information model, the invention provides for suggesting to include the detail in relation to another pairs of elements with partially or fully corresponding properties. Based at least in part on acceptance or refusal, a module based on artificial intelligence is trained in order to decide for further pairs of elements whether to suggest inclusion of the detail.

Abstract: The invention concerns a computer-implemented preprocessing method for dividing a point cloud in cells, whereby for each cell a set of levels of detail is created, each level of detail comprising a set of points and a minimal distance; a data structure for storing a preprocessed point cloud; a computer-implemented rendering method for creating a pixelated image based on a stored preprocessed point cloud and a view frustum; and a viewing method involving a computing system to select a view frustum with a user interface and to present a pixelated image of a point cloud on a screen.

Abstract: In a first aspect the present invention provides a method for manipulating a computer aided design (CAD) model, comprising the following computer-implemented steps of: —creating a first solid entity in a CAD model, said first solid entity comprising one or more coordinates and a 3D volume; —a user executing a drag operation on said first solid entity; wherein said drag operation comprises the following computer-implemented steps: a) selecting a face of said first solid entity; b) determining if said face is a major face or a minor face for said first solid entity; c) determining a drag direction; d) in case of a determined major face executing a moving operation on said first solid entity in said drag direction and in case of a determined minor face executing a push-pull operation on said selected face of said first solid entity in said drag direction.
