A method of representing a component documentation relating to the planning, manufacture and/or maintenance of a component, with the steps: - Providing of a virtual component documentation stored in a digital data memory, which contains a plurality of planning, manufacture and/or maintenance data relating to the planning, manufacture and/or maintenance of the component, which were recorded and documented in a respective planning, manufacture and/or maintenance process, as well as model data of the component, - Providing a projection device having at least one projection glasses, which is a glasses construction to be worn in front of a person's eyes and can generate a projection of virtual images into the environment of the field of view of the person wearing the projection glasses, - Creating a three-dimensional representation of the component from the model data of the component contained in the virtual component documentation by means of a computing unit, - Projecting the three-dimensional representation of the component into the environment of the field of vision of the person wearing the projection glasses by means of the projection glasses, and - Representing at least a part of the component documentation relating to the planning, manufacture and/or maintenance of the component by projecting a part of the planning, manufacture and/or maintenance data of the stored virtual component documentation into the environment of the field of view of the person wearing the projection glasses in relation to the projected three-dimensional representation of the component by means of the projection glasses, - characterized in that a systematic defect is identified from defect-related manufacturing data of the respective component documentation from a plurality of component documentations of different components of the same type stored in the digital data memory by means of an evaluation unit, this identified systematic defect being represented by projecting at least the systematic defect as defect-related manufacturing data of the component documentation in a positionally accurate manner with respect to three-dimensional representation of one of the components into the environment of the person's field of vision by means of the projection glasses. - Providing of a virtual component documentation stored in a digital data memory, which contains a plurality of planning, manufacture and/or maintenance data relating to the planning, manufacture and/or maintenance of the component, which were recorded and documented in a respective planning, manufacture and/or maintenance process, as well as model data of the component, - Providing a projection device having at least one projection glasses, which is a glasses construction to be worn in front of a person's eyes and can generate a projection of virtual images into the environment of the field of view of the person wearing the projection glasses, - Creating a three-dimensional representation of the component from the model data of the component contained in the virtual component documentation by means of a computing unit, - Projecting the three-dimensional representation of the component into the environment of the field of vision of the person wearing the projection glasses by means of the projection glasses, and - Representing at least a part of the component documentation relating to the planning, manufacture and/or maintenance of the component by projecting a part of the planning, manufacture and/or maintenance data of the stored virtual component documentation into the environment of the field of view of the person wearing the projection glasses in relation to the projected three-dimensional representation of the component by means of the projection glasses, - characterized in that a systematic defect is identified from defect-related manufacturing data of the respective component documentation from a plurality of component documentations of different components of the same type stored in the digital data memory by means of an evaluation unit, this identified systematic defect being represented by projecting at least the systematic defect as defect-related manufacturing data of the component documentation in a positionally accurate manner with respect to three-dimensional representation of one of the components into the environment of the person's field of vision by means of the projection glasses.
