Abstract

The method of collaborative work takes place between a first user working on a first object (1) on the basis of a visual representation of the first object displayed in an authoring environment of a first local computer; and a second user working in an authoring environment of a second local computer connected with the first computer via a computer network. The method comprising the steps of:

• • a) selecting at the first computer one type among a plurality of types of data about the first object, each type of data comprising visual representation data about the first object;
  • b) providing to the second computer data about the first object according to the selected type;
  • c) displaying a visual representation of the first object in the authoring environment of the second computer.

b) responsive to the first user selecting the one type, providing to the second computer data about the first object according to the selected type;

c) displaying a visual representation of the first object in the 3D model authoring environment of the second computer.

2. Method according to claim 1, wherein step b) comprises the substep of:

sending at least a part of the data about the first object according to the selected type from the first computer to the second computer.

3. Method according to claim 1, wherein step b) comprises the substeps of:

sending information about a path in the network from the first computer to the second computer;

causing the second computer to download at least a part the data about the first object according to the selected type according to the path in the network.

4. Method according to claim 1, wherein:

in step b), the data about the first object provided to the second computer comprise viewing context data about the visual representation of the first object as displayed on the screen of the first computer;

in step c), the visual representation of the first object is displayed in the 3D model authoring environment of the second computer in a viewing context corresponding to the viewing context data.

5. Method according to claim 1, wherein the first object is defined by first solid geometry data and specifications, the first solid geometry and specifications being available at the first computer.

6. Method according to claim 5, wherein at least one type among the plurality of types of data about the first object does not comprise specifications so that when selected in step a), specifications are not available at the second computer when carrying out step c).

7. Method according to claim 6, wherein one type of data about the first object comprises the first solid geometry data without specifications so that when selected in step a), specifications are not available at the second computer when carrying out step c).

8. Method according to claim 5, wherein one type of data about the first object comprises the first solid geometry data and specifications.

9. Method according to claim 1, wherein one type of data about the first object comprises a snapshot image of at least a part of the visual representation of the first object as displayed on the screen the first local computer.

10. Method according to claim 1, comprising a step of:

displaying a graphical tool on the screen of the first computer, the graphical tool delimiting a zone in the 3D model authoring environment of the first computer;

wherein the zone delimited by the graphical tool in the 3D model authoring environment of the first computer determines the parts of the first object for which visual representation data are comprised in the data about the first object provided in step b).

11. Method according to claim 10, wherein the zone delimited by the graphical tool is adapted to be resized and/or to be changed of location in the 3D model authoring environment of the first computer.

12. Method according to claim 10, comprising a step of:

displaying a graphical tool on the screen of the second computer, the graphical tool delimiting a zone in the 3D model authoring environment of the second computer;

wherein in step c), the visual representation of the first object in the 3D model authoring environment of the second computer is displayed in the zone delimited by the graphical tool in the 3D model authoring environment of the second computer.

13. Method according to claim 1, comprising a step of:

displaying a chat-entry box and a chat-display box on the screen of the first computer and on the screen of the second computer enabling the first user and the second user to exchange messages via the network.

14. Method according to claim 1, wherein:

the second user works on a second object on the basis of a visual representation of the second object displayed in the 3D model authoring environment of the second local computer;

in step c), the visual representation of the first object is displayed together with a visual representation of the second object in the 3D model authoring environment of the second computer so as to provide a combined representation of the first object and of the second object in a same viewing context.

15. Computer program product comprising a computer readable storage device embodying program code which when executed by a programmable processor implements the steps defined in claim 1 for said first and/or said second computer.

16. Computer program product according to claim 15 configured to allow collaborative work of said first user with said second user, wherein the program code running on said first computer enables said first user:

to select at said first computer said one type among a plurality of types of data about the first object, each type of data comprising visual representation data about said first object; and

to send from said first computer to said second computer said data about said first object according to said selected type and/or information about a path in said network where data about the first object according to said selected type are downloadable.

17. Method of collaborative work between:

a first user working on a first object on the basis of a visual representation of the first object displayed in a 3D model authoring environment of a first local computer; and

a second user working on a second object on the basis of a visual representation of the second object displayed in a 3D model authoring environment of the second local computer, the 3D model authoring environment of the second local computer not being the 3D model authoring environment of the first local computer;

wherein the first computer and the second computer are connected via a computer network, the method comprising the steps of;

a) enabling at the first computer user selection of one type among a plurality of types of data about the first object, each type of data comprising visual representation data about the first object;

b) responsive to user selection at the first computer, providing to the second computer data about the first object according to the selected type;
