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 determining exploded paths 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 (LIST) of thumbnails (TH1, TH2, TH3), a thumbnail corresponding to at least one possible set of computed exploded paths of the assembly;

selecting (4) one thumbnail (TH3) among the list of thumbnails; and

displaying (5) the selected thumbnail (TH3).

2. Computer-implemented method according to claim 1, wherein an exploded line of an exploded path comprises:

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

/or

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

3. Computer-implemented method according to claim 1, wherein the step of selecting one thumbnail (TH3) among the list (LIST) of thumbnails (TH1, TH2, TH3) is preceded by a step of previewing at least one thumbnail of the list (LIST) of thumbnails (TH1, TH2, TH3).

4. Computer-implemented method according to claim 1, wherein the step of displaying the selected thumbnail (TH3) is performed by replacement of the current view in the main frame.

5. Computer-implemented method according to claim 4, wherein the step of selecting one thumbnail (TH3) among the list (LIST) of thumbnails (TH1, TH2, TH3) is preceded by a step of previewing at least one thumbnail of the list of thumbnails in the main frame.

6. Computer-implemented method according to claim 5, wherein said constraint set comprises at least one constraint among a passage area, a waypoint, an axis, an avoid area, and an avoid point.

7. Computer-implemented method according to claim 1, wherein the steps of computing and of displaying the list (LIST) of thumbnails (TH1, TH2, TH3) use a scheduling criterion.

8. Computer-implemented method according to claim 7, wherein said scheduling criterion uses at least one geometrical criterion among a criteria set comprising:

collinearity of parts of a representation of one set of computed exploded paths of the assembly, passing through identical points for parts of a representation of one set of computed exploded paths of the assembly, and a preferred direction of parts of a representation of one set of computed exploded paths of the assembly.

9. Computer-implemented method according to claim 7, wherein the step of selecting one thumbnail (TH3) among the list (LIST) of thumbnails (TH1, TH2, TH3) uses automatically by default said scheduling criterion with the displaying of the thumbnail (TH1) of the list (LIST) of thumbnails (TH1, TH2, TH3) having the best value of said scheduling criterion.

10. Computer-implemented method according to claim 1, wherein the steps of previewing at least one thumbnail of the list (LIST) of thumbnails (TH1, TH2, TH3) and of selecting one thumbnail among the list (LIST) of thumbnails (TH1, TH2, TH3) comprise the use of a choice selector (SEL).

11. Computer-implemented method according to claim 10, wherein the choice selector (SEL) is adapted to be controlled by pointing means.

12. Computer-implemented method according to claim 10, wherein the step of previewing uses a first interaction with the choice selector (SEL), and the step of selecting uses a second interaction with the choice selector (SEL).

13. A computer system comprising:

a processor; and

a computer readable medium having computer-executable instructions that cause the processor to determine exploded paths of an exploded view of an assembly of three-dimensional modeled objects by;

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 (LIST) of thumbnails (TH1, TH2, TH3), a thumbnail corresponding to at least one possible set of computed exploded paths of the assembly;

selecting (4) one thumbnail (TH3) among the list of thumbnails; and

displaying (5) the selected thumbnail (TH3).

14. A computer program product, comprising:

a computer readable medium, for determining exploded paths of an exploded view of an assembly of three-dimensional modeled objects, comprising code means; and

the code means causing one or more computers to;

display (1) in a main frame an exploded view of the assembly in a scene;

compute (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;

display (3) a list (LIST) of thumbnails (TH1, TH2, TH3), a thumbnail corresponding to at least one possible set of computed exploded paths of the assembly;

select (4) one thumbnail (TH3) among the list of thumbnails; and

display (5) the selected thumbnail (TH3).

15. A computer apparatus for determining exploded paths of an exploded view of an assembly of three-dimensional modeled objects comprising:

means for implementing displaying (1) in a main frame an exploded view of the assembly in a scene;

computing means for 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;

display means for displaying (3) a list (LIST) of thumbnails (TH1, TH2, TH3), a thumbnail corresponding to at least one possible set of computed exploded paths of the assembly;

user selection means for selecting (4) one thumbnail (TH3) among the list of thumbnails; and

the display means further responsively displaying (5) the selected thumbnail (TH3).
