Computerized collaborative work

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