Annotating a 3d modeled object representing a cad mechanical part or assembly of parts

A non-transitory computer readable storage medium having recorded thereon a computer program that when executed by a computer causes the computer to implement a method for annotating a 3D modeled object representing a CAD mechanical part or assembly of parts, two or more views of the 3D modeled object being displayed and at least one of the views being compliant with a view of a technical drawing, the method comprising:

• obtaining a 3D scene and displaying:
• an orientation-free view of the 3D modeled object, and
• at least one fixed view of the 3D modeled object;
• creating, upon user action, an annotation by selecting at least one geometrical element on at least one of the views of the 3D modeled object and an annotation type;
• and
• displaying the created annotation on at least the orientation-free view.

A system comprising:

• a processor coupled to a memory and a graphical user interface, the memory having recorded thereon a computer program for annotating a 3D modeled object representing a CAD mechanical part or assembly of parts, two or more views of the 3D modeled object being displayed and at least one of the views being compliant with a view of a technical drawing, that when executed by that processor causes the processor to be configured to:
• obtain a 3D scene and display:
• an orientation-free view of the 3D modeled object, and
• at least one fixed view of the 3D modeled object;
• create, upon user action, an annotation by selecting at least one geometrical element on at least one of the views of the 3D modeled object and an annotation type;
• and
• display the created annotation on at least the orientation-free view.
