To Insert a Geometric Tolerance into a Drawing
1. On the Annotate tab, click 
Geometric Tolerance. A dynamic preview of the unattached geometric tolerance (GTOL) frame appears.
Geometric Tolerance. A dynamic preview of the unattached geometric tolerance (GTOL) frame appears. | By default, the previewed GTOL frame is filled with the data of the last placed GTOL within the current drawing. However, for the first GTOL in the drawing, the GTOL frame is previewed with Position geometric characteristic with the value of 0.001. |
2. Define the owner of the GTOL.
Right-click the previewed GTOL frame and set the Destination for the GTOL. By default, the drawing is set as the destination. You can change the GTOL destination to the model, if you want to establish associativity with the datums owned by the model.
| | In Creo Parametric 3.0 or previous releases, the default owner of a GTOL inserted into a drawing was the corresponding model. This was done to establish full associativity between the GTOL and the model datums, because the datums and the GTOL were owned by the model. Any changes made in a datum in the model environment were reflected in the GTOL in the drawing environment. You could also select the current drawing as the owner of a GTOL inserted in the drawing. However, in that case, the GTOL would not recognize the datums owned by the drawing or the model. |
3. Define the mode for reference selection and placement of the GTOL. Right-click on the previewed GTOL frame. You can select one of the following modes:
◦ Automatic — This is the default mode, with which you can create the following GTOL attachments:
▪ Free (unattached) GTOL. You can click on a location in the graphics area to place the GTOL.
▪ GTOL with its leader attached to the model geometry, such as edge, dimension witness line, coordinate system, axis center, axis lines, curves, or surface points, vertices, section entities, or draft entities.
▪ GTOL attached to a dimension or dimension elbow.
| | You can right-click and select Dimension Elbow command on the shortcut menu to attach the GTOL to the dimension elbow. |
▪ GTOL attached to a note elbow
▪ GTOL attached to another GTOL
▪ GTOL attached to another Datum Tag
◦ Make Dim — This mode allows you to create a dimension line and place the GTOL frame attached to it.
◦ Offset — This mode allows you to place the GTOL frame at an offset from the following drawing objects:
▪ Dimension
▪ Dimension Arrow
▪ GTOL
▪ Note
▪ Symbol
| | Before you place the GTOL, you can press ESC to terminate the GTOL creation process. |
4. Middle-click to place the GTOL frame. You can drag the GTOL frame to reposition the GTOL.
The Geometric Tolerance ribbon tab opens.
5. On the Geometric Tolerance ribbon tab, you can define the following properties for the placed GTOL:
◦ Specify the geometric characteristics of the GTOL as:
 —Straightness |  —Flatness |  —Circularity |
 —Cylindricity |  —Profile of a line |  —Profile of a surface |
 —Angularity |  —Perpendicularity |  —Parallelism |
 —Position |  —Concentricity |  —Symmetry |
 —Runout |  —Total Runout |
◦ Specify the model and the reference entity to which to add the geometric tolerance, as well as place the geometric tolerance on the drawing.
◦ Specify the datum references and material conditions for a geometric tolerance, as well as the value and datum reference of a composite tolerance.
◦ Specify the tolerance value and the material condition.
◦ Specify the geometric tolerance’s symbols and modifiers, as well as the projected tolerance zone.
◦ Specify additional text that you want associated with a geometric tolerance while creating or editing it.
6. Click in the graphics area to insert the GTOL at the specified location.
To Create Additional Leaders for a GTOL
1. Create a GTOL with a normal or tangential leader.
2. Right-click a GTOL, and select Add Leader.
3. Select a reference on which to place the leader.
