Abstract

A computer-implemented method for determining exploded path of an exploded view of an assembly of three-dimensional modeled objects comprising the steps of displaying (1) in a main frame an exploded view of the assembly in a scene; computing (2) at least one set of exploded paths, an exploded path corresponding to a set of at least one exploded line linking at least one object of the assembly; displaying (3) a list of thumbnails, a thumbnail corresponding to at least one possible set of computed exploded paths of the assembly; selecting (4) one thumbnail among the list of thumbnails; and displaying (5) the selected thumbnail.

Claims

1. A computer-implemented method for producing an illustration based on an assembly of three-dimensional modeled objects by determining exploded paths of an exploded view of the assembly of three-dimensional modeled objects, the method comprising:

displaying, in a main frame of a graphical user interface (GUI) of a computer aided design (CAD) system, an exploded view of the assembly in a three-dimensional scene;

automatically computing different exploded paths, each exploded path comprising at least one exploded line, the at least one exploded line of each exploded path based on at least one geometrical criterion, the geometrical criterion including at least a preferred direction of parts of a representation of one of the computed exploded paths of the assembly, each exploded path including a plurality of exploded lines linking objects of the assembly, each of said exploded paths corresponding to a respective order for mounting or dismounting said objects of the assembly;

simultaneously displaying a second frame of the GUI and the main frame of the GUI, the second frame displaying a list of thumbnails, each thumbnail of the list displaying the exploded view of the assembly and one of the automatically computed exploded paths;

automatically preselecting, within the GUI, a default thumbnail, of the list of thumbnails, having a best value of the geometrical criterion;

enabling a user to select, within the GUI, one thumbnail among the list of thumbnails; and

producing the illustration displaying the exploded path of the selected thumbnail in the main frame of the GUI.

2. The computer-implemented method according to claim 1, wherein the at least one exploded line of each exploded path comprises one or more of:

at least one line linking two positions of at least one object, being a segment or a curve; and

at least one custom line comprising at least one line with a constraint set of at least one geometrical constraint.

3. The computer-implemented method according to claim 2, wherein said constraint set comprises at least one constraint among a passage area, a waypoint, an axis, an avoid area, and an avoid point.

4. The computer-implemented method according to claim 1, wherein enabling the user to select the one thumbnail among the list of thumbnails is preceded by previewing at least one thumbnail of the list of thumbnails.

5. The computer-implemented method according to claim 1, wherein displaying the selected thumbnail is performed by replacing a current view in the main frame.

6. The computer-implemented method according to claim 5, wherein enabling the user to select one thumbnail among the list of thumbnails is preceded by previewing at least one thumbnail of the list of thumbnails in the main frame.

7. The computer-implemented method according to claim 1, wherein enabling selection of selecting one thumbnail among the list of thumbnails comprises using a choice selector.

8. The computer-implemented method according to claim 7, wherein the choice selector is adapted to be controlled by pointing means.

9. The computer-implemented method according to claim 7, further comprising previewing the exploded path of a selected thumbnail by using a first interaction with the choice selector;

wherein selecting uses a second interaction with the choice selector.

10. A computer system comprising:

a processor; and

a non-transitory readable medium having computer-executable instructions that cause the processor to producing an illustration based on an assembly of three-dimensional modeled objects by determining exploded paths of an exploded view of the assembly of three-dimensional modeled objects by;

displaying, in a main frame of a graphical user interface (GUI) of a computer aided design (CAD) system, an exploded view of the assembly in a three-dimensional scene;

automatically computing different exploded paths, each exploded path comprising at least one exploded line, the at least one exploded line of each exploded path based on at least one geometrical criterion, the geometrical criterion including at least a preferred direction of parts of a representation of one of the computed exploded paths of an assembly, each exploded path including a plurality of exploded lines linking objects of the assembly, each of said exploded paths corresponding to a respective order for mounting or dismounting said objects of the assembly;

simultaneously displaying a second frame of the GUI and the main frame of the GUI, the second frame displaying a list of thumbnails, each thumbnail of the list displaying the exploded view of the assembly and one of the automatically computed exploded paths;

automatically preselecting, within the GUI, a default thumbnail, of the list of thumbnails, having a best value of the geometrical criterion;

enabling a user to select, within the GUI, one thumbnail among the list of thumbnails; and

producing an illustration displaying the exploded path of the selected thumbnail in the main frame of the GUI.

11. A computer program product, comprising:

a non-transitory computer readable medium, for producing an illustration based on an assembly of three-dimensional modeled objects by determining exploded paths of an exploded view of the assembly of three-dimensional modeled objects, comprising instructions; and

the instructions causing one or more computers to;

display, in a main frame of a graphical user interface (GUI) of a computer aided design (CAD) system, an exploded view of the assembly in a three-dimensional scene;

automatically compute different exploded paths, each exploded path comprising at least one exploded line, the at least one exploded line of each exploded path based on at least one geometrical criterion, the geometrical criterion including at least a preferred direction of parts of a representation of one of the computed exploded paths of an assembly, each exploded path corresponding to a plurality of exploded lines linking objects of the assembly, each of said exploded paths corresponding to a respective order for mounting or dismounting said objects of the assembly;
