Abstract: A method and apparatus for identifying a potential movement of a part containing features. First lines are formed by a computer system on a plane extending from a rotation point on the plane to centers of the features in a feature pattern. Second lines are formed by the computer system on the plane extending from the centers of the features in which the second lines are substantially perpendicular to corresponding first lines. Third lines are formed by the computer system extending from ends of the second lines in which the third lines are substantially perpendicular to the plane. Elongate volumes are formed by the computer system extending from the centers of the features to ends of the third lines. An intersection of the elongate volumes is formed by the computer system. The potential movement of the part containing the features is identified using the intersection.

Abstract: A method, apparatus, and computer program product for identifying associations in a model of a structure. A number of fastener locations is identified in the model of the structure. A line segment extends through each of the number of fastener locations to form a number of line segments. The line segment extends a selected distance away from an associated fastener location in the number of fastener locations. A number of parts is identified through which the line segment extends to form a number of identified parts for a fastener for each of the number of line segments.

Abstract: A method, apparatus, and computer program product for identifying gaps. A grid of points is generated on a first surface. The grid of points is associated with a point for a first part associated with a second part in a model. A line segment is formed from the first surface of the first part to a second surface of the second part for each point in the grid of points to form a plurality of line segments. A gap size is identified between the first surface and the second surface using the plurality of line segments to form a plurality of gap measurements.

Abstract: The invention discloses differing embodiments of methods for checking the location or potential location of one or holes in structure relative to edges, fillets, and thickness changes. The area in the vicinity of the hole may be checked in order to determine whether the location or potential location of the hole meets a pre-determined threshold. If the location or potential location of the hole does not meet the pre-determined threshold, the hole may be flagged as being a potential problem. In such manner, the suitability of the hole for insertion of a fastener device may be determined. In other embodiments, apparatus are disclosed having one or more fastener devices extending through one or more holes in a structure. The location of the one or more holes may have been approved for insertion of the one or more fastener devices utilizing a pre-determined threshold standard.
