Annotations: Geometric Tolerances
The methods in this section allow a Creo Object TOOLKIT Java application to read, modify, and create geometric tolerances (gtols) in a solid or drawing. We recommend that you study the Creo Parametric documentation on geometric tolerances, and develop experience with manipulating geometric tolerances using the Creo Parametric commands before attempting to use these methods.

    Use the method wfcGTol.wfcGTol.GTolAttachDatum_Create to create an attachment for a specified datum inside a gtol. The input argument Datum is specified using the pfcModelItem.ModelItem class.
    The methods wfcGTol.GTolAttachDatum.GetDatum and wfcGTol.GTolAttachDatum.SetDatum get and set the attachments for datum type of gtol.
    From Creo Parametric 4.0 F000 onward, datum symbols are defined using datum feature symbol. The methods work with the new datum feature symbol along with the legacy datum tag annotations.
    Use the method wfcGTol.GTol.SetAttachAnnotation to set the attachment options for annotation type of gtol. The input argument Attach is specified using the class wfcGTol.GTolAttachAnnotation.
    Use the method wfcGTol.wfcGTol.GTolAttachAnnotation_Create to create an attachment for a specified annotation inside a gtol. The input argument Annotation is specified using the wfcAnnotation.Annotation class.
    The methods wfcGTol.GTolAttachAnnotation.GetAnnotation and wfcGTol.GTolAttachAnnotation.SetAnnotation get and set the attachments for annotation type of gtol.
    Use the method wfcGTol.GTol.SetAttachOffset to set the offset references for the geometric tolerance. The input argument Attach is specified using the class wfcGTol.GTolAttachOffset.
    Use the method wfcGTol.wfcGTol.AttachOffset_Create to create an attachment for a gtol with offset references. The input arguments are:
    •  OffsetRef—Specifies the offset reference.
    •  Offset—Specifies the position of the offset reference as model coordinates.
    The methods wfcGTol.GTol.AttachOffset.GetOffset and wfcGTol.GTol.AttachOffset.SetOffset get and set the position of the offset reference as model coordinates using the class pfcBase.Vector3D.
    The methods wfcGTol.GTol.AttachOffset.GetOffsetRef and wfcGTol.GTol.AttachOffset.SetOffsetRef get and set the offset reference using the class pfcSelect.Selection. The reference can be a dimension, arrow of a dimension, another geometric tolerance, note, or a symbol instance. If there are no offset references, the output argument returns NULL.
    Use the method wfcGTol.GTol.SetAttachMakeDimension to set all the attachments options to create a geometric tolerance with Make Dim type of reference. The input argument Attach is specified using the class wfcGTol.GTolAttachMakeDimension.
    Use the method wfcGTol.wfcGTol.AttachMakeDimension_Create to create an attachment for a gtol with Make Dim type of reference.
    Use the methods wfcGTol.GTol.AttachMakeDimension.GetLocation and wfcGTol.GTol.AttachMakeDimension.SetLocation to get and set the location of the gtol text in a specified gtol using the class pfcPoint3D.
    Use the methods wfcGTol.GTol.AttachMakeDimension.GetOrientHint and wfcGTol.GTol.AttachMakeDimension.SetOrientHint to get and set the orientation of the gtol using the enumerated type pfcDimension.DimOrientationHint and one of the valid values are:
    •  ORIENTATION_HINT_HORIZONTAL
    •  ORIENTATION_HINT_VERTICAL
    •  ORIENTATION_HINT_SLANTED
    •  ORIENTATION_HINT_ELLIPSE_RADIUS1
    •  ORIENTATION_HINT_ELLIPSE_RADIUS2
    •  ORIENTATION_HINT_ARC_ANGLE
    •  ORIENTATION_HINT_ARC_LENGTH
    •  ORIENTATION_HINT_LINE_TO_TANGENT_CURVE_ANGLE
    •  ORIENTATION_HINT_RADIAL_DIFF
    Use the methods wfcGTol.GTol.AttachMakeDimension.GetDimSenses and wfcGTol.GTol.AttachMakeDimension.SetDimSenses to get and set the information about how the gtol attaches to each attachment point of the model or drawing. The input argument value is specified using the class pfcDimension.DimSenses.
    Use the methods wfcGTol.GTol.AttachMakeDimension.GetDimAttachments and wfcGTol.GTol.AttachMakeDimension.SetDimAttachments to get and set the points on the model or drawing where the gtol is attached. The input argument value is specified using the class pfcSelect.DimensionAttachments.
    Use the methods wfcGTol.GTol.AttachMakeDimension.GetAnnotationPlane and wfcGTol.GTol.AttachMakeDimension.SetAnnotationPlane to get and set the annotation plane in a specified gtol using the class wfcAnnotation.AnnotationPlane.
