To Specify Tolerance
When you start defining the Tolerance element, the TOLERANCE menu appears with the following options:
CurrentModel—Use the CMM model to select the dimension or gtol to verify. Select the feature(s) on the reference part to display the dimensions, along with geometric tolerances, then pick the dimension or gtol you want to verify.
* 
To pick an annotation element, you can either select it directly from the screen or from the model tree.
From Drawing—Use a drawing of the reference part to select the dimension or gtol to verify. The system prompts you to enter the name of the drawing; entering a question mark (?) opens the browser to let you search for the drawing, starting in the current directory. Once you specify the drawing name, the system retrieves it in the Creo Parametric window. Pick the dimension or gtol in the drawing. To switch to another sheet of the drawing, select the sheet number from the Creo Parametric toolbar.
You can verify the following types of tolerances:
Dimension
Diameter
Radius
Linear
Angular—Cone
Angular—Other
Orientation
Parallelism
Perpendicularity
Angularity
Location
Position
Symmetry
Concentricity
Form
Flatness
Straightness
Circularity
Cylindricity
Profile
Surface
When you select a dimension or gtol, the system extracts from it certain tolerance properties, depending on its type. It will then prompt you to select the features or datums necessary to verify this dimension or gtol.
