Abstract: A CAD model comprises an entity comprising an input face comprising a normal direction. Via user input, a translation for the input face in the normal direction is obtained. From the CAD model, a list of faces parallel to the input face is automatically determined. From the list of faces, a snap face comprising a distance along the normal direction to the current position of the input face which is minimal over the list of faces is automatically selected, without acquiring the snap face via user input. Via a visualization means, a snap plane comprising the snap face, and either a coplanar alignment of the input face in the snap plane; or a distance indicator from the input face to the snap plane, are automatically displayed. Via user input, validation of the coplanar alignment or a numerical value for the distance indicator is obtained. The entity is automatically adjusted accordingly.

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 disclosed method for manipulating a computer aided design (CAD) model includes the computer-implemented steps of a user determining one or more entities in a CAD model with a cursor, determining a set of adequate user action(s) to execute on the entities and providing a suggestion menu which contains the set of adequate user actions, partly determined by previously executed user actions. A second method for manipulating a CAD model includes the computer-implemented steps of a user determining one or more entities with a cursor, determining a set of adequate user actions to execute on the entities and providing a suggestion menu which contains the set of adequate user actions, partly determined by a geometric analysis on any of the entities in an area within a predetermined proximity of the cursor. A computer program product and server for manipulating a CAD model are also described.
