A method for producing a negative mold for casting a turbine blade with a blade platform and at least one fastening element for fastening the turbine blade to a blade fixture is provided. The device has a needle that includes an elongated body and a needle hub. The kinetic texture features are then used in a classification process which classifies the ROIs as vulnerable or stable. If a conflict is found, the conflicting change may be saved to the document as a comment, allowing for the user to choose when to resolve the conflict. The inclination calculation apparatus then calculates an inclination of the input device using the first inclination information and the second inclination information.
