Used to define a GD and T angularity tolerance with a cylindrical zone. Used to record the measured value of a GD and T angularity tolerance with a planar zone shape. Used to define a GD and T angularity tolerance with a planar zone. Used to list all of the tolerances applied to a feature. Most useful when the tolerance has not been analyzed and therefore there is no tolerance actual to tie the tolerance to the feature. Used to define a circular arc which is less than 360 degrees. Used to record the measured arc feature. Used to define the nominal information for an arc feature. An analysis setting A point on the axis for axial features The direction vector for axes When measured point data is reported, including the radius allows an application to switch between tip comp'ed and tip center. Records the feature IDs which constructed features are built from. Used to store the indentifier of the geometry which the feature is based on. Used to identify a CAD model associated to the inspection program. Feature data fitting mode for circle, cone, cylinder, parpln, sphere, torus Used to store the XYZ point. Used to define a complete circle. Used to define the measured circle feature. Used to define the nominal information for a circle feature. Used to define the circular runout GDandT tolerance type. Used to define the indivdual runouts for a circular runout tolerance. Used to define the circularity GDandT tolerance type. Used to record the measured output of a circularity tolerance. Used to define a slot or tab when both width and length are going to be measured. These are also referred to as elongated holes. Used to record the measured information for a closed_slot feature. Used to define the nominal information for a closed_slot feature. Used to define if the point data has been compensated for tip radius. Used to store the lower callout in a composite position tolerance. It is an optional element for a position tolerance. used to record the lower callout value in a composite position tolerance. If is an optional element to position_actual element Used to store the lower callout in a composite profile tolerance. It is an optional element to the profile tolerance Used to record the lower callout value in a composite position tolerance. It is an optional element to the profile_actual element. Used to store the references to two datums. This an older wireframe based feature type. Most systems today use faces and surfaces, so this feature type is close to obsolete. Refer to the DMIS standard for rules to construct the circle. Refer to the DMIS standard for rules to construct the closed slot. Refer to the DMIS standard for rules to construct the cone. Refer to the DMIS standard for rules to construct the cylinder Used to define datums. This is important if applications want to recreate GD and T control frames. Used to specify the diameter for circular or cylindrical features Used to specify the calculated diameter for circular or cylindrical features Used to define a delta type diameter tolerance, 5.0 +0.2 -0.1 Used to define a limit type diameter tolerance, 4.9 5.2 Used when an analysis package applies a fitting algorythm that has a high and low value. For example a least squares fit might record the +2 STD. Dev. Used when an analysis package applies a fitting algorythm that has a high and low value. For example a least squares fit might record the -2 STD. Dev. The very main element that all data is attached. This is the element that stores all non dimensional data for dataset. Used to record the measured distance between two features. If the nominal tolerance is a limit, the distance is the total distance between the two features. If the nominal tolerance is a delta, the distance is the deviation from nominal (actual - nominal). Used to define a delta type distance between two features tolerance, 5.0 +0.2 -0.1 Used to define a limit type distance between two features tolerance, 4.9 5.2 A sub element to analysis DOF element which specifies whether the particular limit is on, off or bounded by limits. This transform is used to place the tolerance zones in their actual position relative to common space. For GD and T tolerances that have datums, it is the transform that maps common space to DRF space. This transform is used to place the tolerance zones in their nominal position relative to common space. This is used to define a point on the edge of a surface. Used in the definition of a cone feature. It records the distance of the small end of the cone from the base point. Used to define a feature. All the information relative to the feature is added and children elements. Used to record the analysis modes specific to calculating feature actuals from point lists. This overrides the default settings. Used to record the analysis modes specific to calculating feature actuals from point lists. Applies to all features that don't explicity state their own modes. This is the element that stores all feature elements. This is used when defining angle between tolerances when the intersection might be ambiguous. For example when the included angle is close to zero or 180. This records the time in GMT (not local time) when the inspection completed. For systems that do both inspection and analysis, it would imply completion of both inspection and the analysis. This records the time in GMT (not local time) when the inspection started. Used to define the length of an axis or line. A positive value would mean in the direction of the associated vector and a negative value would mean in the opposite direction. This is the worst deviation on the inside of material. It is negative if the devation represents a point inside of material and positive if outside. The largest devation outside of material. Positive if the point is outside material and negative if inside. A negative value implies that all deviation is inside material. Used in the definition of an ellipse. Records the scalar deviation for a distance. Used for systems that can record a distance, but does not have direction information. Used to record the overall status of an inspection. For example to have a status of PASS, all tolerance in the program must has status of PASS. Used in the definition of a cone feature. It records the offset of the large end of the cone from the base point.
